Showing you how to make homemade protein bars that are paleo-friendly – made with dates, nuts, egg white protein powder and different mix-ins for your favorite homemade RXBAR bar flavors.

I did a thing: I made you HOMEMADE PROTEIN BARS!

Actually, I made you four flavors.

Except these aren’t just any kind of protein bar… these are like homemade RXBARS. Have you heard of RXBAR? Tried them? They’re known for their simplistic packaging, calling out the ingredients on the front of their bar wrapper – it’s just dates, nuts, egg white protein and then other additional ingredients depending on the flavor.

Homemade Protein Bars with Dates and Nuts

Guess what? You can basically make the same thing as an RXBAR at home.

I actually have my base recipe here, which is where I share the most simple version of this recipe.

But I wanted to give you specific flavor options, show you how easy they’re made from start to finish plus some more tips and tricks so you’ll feel super confident making these homemade protein bars / energy bars / paleo protein bars – whatever you want to call them.

And you have 4 FLAVORS and WAYS to enjoy them in this one post.

Main ingredients needed

The three main ingredients needed for a homemade RXBAR recipe is:

  • Medjool dates–I like Medjool dates best because they’re thicker and juicer than others. Ratios may change if using other dates that are smaller or dry.
  • Nuts – You can really use a mix of nuts. For every recipe / flavor combination you need 2 cups of nuts. I like to use a mix of cashews, almonds, walnuts, pecans and peanuts, depending on the recipe. Peanuts are not paleo or Whole30® compliant so feel free to sub cashews or a mix when we get to the Peanut Butter Chocolate Chip flavor.
  • Egg White Protein Powder – This is where most of your protein comes from in the recipe. Egg white protein<– linked to the one I usekeeps this recipe paleo-friendly, Whole30® compliant and also vegetarian. I don’t have an equal 1:1 sub for another protein powder in this recipe. See more notes in the recipe card.

You’ll also need water to help the mixture come together at the end. The rest of the ingredients and ratio of ingredients needed will depend on the flavor you’re making.

Don’t worry, we’ll go over everything. Just keep reading.

How to Make Homemade Protein Bars (AKA copycat RXBARS)

First things first: you need a food processor or high powered blender to make these. The nuts are dates are best broken down with super sharp and powerful blades. A NutriBullet or standard blender won’t really cut it.

I’ll list each recipe flavor and ingredients needed but scroll down further for more flavor adaptations, notes and the recipe card.

Pineapple Mango Protein Bars

Homemade Protein Bar Recipe {copycat RX BAR} • Fit Mitten Kitchen (5)

Ingredients

  • 1 cup cashews
  • 1 cup almonds
  • 1 cup egg white protein powder
  • 10 large medjool dates, pitted
  • 2oz dried unsweetened mango
  • 2 oz dried unsweetened pineapple
  • 2-4 tbsp water, as needed

Steps

First the nuts get broken down with the egg white protein powder.

Then the dates and (soaked) dried mango plus pineapple get added to the bowl.

This is where the mixture almost comes together. And you’ll see just by adding tablespoons of water (usually 2-4 total) helps the protein bar mixture get sticky enough to where it will press into a pan.

Blueberry Protein Bars

Homemade Protein Bar Recipe {copycat RX BAR} • Fit Mitten Kitchen (7)

Ingredients

  • 1 cup cashews
  • 1 cup walnuts
  • 1 cup egg white protein powder
  • 10 medjool dates
  • 1 cup dried unsweetened blueberries
  • 2-4 tbsp water, as needed

You can change out the nuts as you’d like. Process described above is the same!

Mint Chocolate Protein Bars

Homemade Protein Bar Recipe {copycat RX BAR} • Fit Mitten Kitchen (8)

Ingredients

  • 1 cup walnuts
  • 1 cup cashews
  • 1 cup egg white protein powder
  • ⅓ cup cacao powder (or unsweetened cocoa but use “cacao” for video)
  • 18 large medjool dates
  • ½ tsp mint extract
  • 2-4 TBSP water, as needed

There isn’t any dried fruit added here so the amount of Medjool dates increases. You can also use a mix of nuts or even all walnuts.

Peanut Butter Chocolate Chip Protein Bars

Homemade Protein Bar Recipe {copycat RX BAR} • Fit Mitten Kitchen (9)

Ingredients

  • 2 cups unsalted peanuts
  • 1 cup egg white protein powder
  • 18 large medjool dates
  • 3-5 TBSP water, as needed
  • ½ cup mini dairy-free chocolate chips

This flavor is not paleo (because, peanuts) but it sure is delicious and kind of doubles as a great treat! If you like peanut butter 😀

Tips for making copycat RXBARs

  • While pulsing in the Medjool dates and other mix-ins (i.e. pineapple, mango, or blueberries) the mixture may look dry. Continue processing and being adding water one tablespoon at a time, letting the motor continue to run about 5 seconds in between each water addition. You *can* overmix these which will lead to a gummy and sticky texture. The mixture comes together in the pan as well once it is pressed together.
  • For the fruit based flavors, you don’t need as many Medjool dates because you’re adding in the dried fruit.
  • Use a lightly oiledpastry roller for flattening out the mixture in the pan. The oil prevents the mixture from sticking to the wood. Wetting it will also help.Alternatively, you can take a square piece of parchment paper and flatten with your hands are a large flat measuring cup.
  • You can cut these homemade protein bars into 16 squares, 12 rectangles, or even shape them into balls or flatten into cookies. Note the nutrition per serving will change.

Adaptations / Looking for more flavors?

  • For Chocolate Sea Salt: simply omit the mint extract from the Mint Chocolate flavor and top the bars with flaked sea salt before placing in fridge or freezer to set.
  • For Apple Cinnamon: use the Blueberry flavor as your base but sub the dried blueberries for dried unsweetened apple slices (4oz) and add 1 tablespoon cinnamon. You could also use pecans as part of the nut mix for additional flavor.
  • For Chocolate Coffee: Use this recipe already posted on my site.
  • For Mixed Berry: Use the Blueberry flavor as your base but use a mix of dried blueberries, dried raspberries and dried cranberries (equal to 1 cup). I would opt for all cashews here or a mix of cashews and almonds.

Pumpkin Spice Paleo Protein Bars

  • These ones use collagen peptides!

Coffee Cacao Date Nut Protein Bars

Banana Bread Date Nut Energy Bars

  • This recipe doesn’t call for egg white protein powder but you could add it in, you’d just need more water to get the mixture to come together. Or use 60 grams collagen peptides with no additional water.

  • 24 tablespoons water, as needed

Peanut Butter Chocolate Chip

Instructions

Pineapple Mango

  • If dates or dried mango and pineapple are super dry, soak in warm water for 3-4 minutes then drain well.
  • Line a 8×8 pan with parchment paper (or use silicone pan), set aside.
  • In the bowl of your food processor with S blade, process almonds, cashews, and egg white protein until nuts have broken down into small pieces.
  • Add in pitted dates, dried mango and pineapple; process until combined–the mixture will look a little dry. With the motor running about 1 tablespoon of water at a time until mixture is sticky and everything comes together. Depending on if your dates were juicy or dry, you may need less or more water.
  • Once mixtures has come together and is sticky, transfer to lined 8×8 pan or silicone pan. Use slightly wet hands to press evenly into pan. I use his fun little pastry roller to make it extra flat.
  • Place pan in fridge for 1 hour, or freezer for 30 minutes before cutting into bars. Use large sharp knife and cutting board, cutting bars into 12 or 16 squares.

Blueberry

  • Line a 8×8 pan with parchment paper (or use silicone pan), set aside.
  • In the bowl of your food processor with S blade, process cashews, walnuts and egg white protein until nuts have broken down into small pieces.
  • Add in pitted dates and dried blueberries; process until combined–the mixture will look a little dry. With the motor running about 1 tablespoon of water at a time until mixture is sticky and everything comes together. Depending on if your dates were juicy or dry, you may need less or more water.
  • Once mixtures has come together and is sticky, transfer to lined 8×8 pan or silicone pan. Use slightly wet hands to press evenly into pan.
  • Place pan in fridge for 1 hour, or freezer for 30 minutes before cutting into bars. Use large sharp knife and cutting board, cutting bars into 12 or 16 squares, or roll into balls.

Mint Chocolate

  • Line a 8×8 pan with parchment paper (or use silicone pan), set aside.
  • In the bowl of your food processor with S blade, process walnuts, cashews and egg white protein until nuts have broken down into small pieces.
  • Add in cacao powder, pitted dates and mint extract; process until combined. With the motor running add about 1 tablespoon of water at a time until mixture is sticky and everything comes together. Depending on if your dates were juicy or dry, you may need less or more water.
  • Transfer to lined 8×8 pan or silicone pan. Use slightly wet hands to press evenly into pan or use pastry roller.
  • Place pan in fridge for 1 hour, or freezer for 30 minutes before cutting into bars. Use large sharp knife and cutting board, cutting bars into 12 or 16 squares. Or try rolling into tablespoon size balls.

Peanut Butter Chocolate Chip

  • Line a 8×8 pan with parchment paper (or use silicone pan), set aside.
  • In the bowl of your food processor with S blade, process peanuts and egg white protein until nuts have broken down. It won’t take much because the peanuts are already fairly small.
  • Add in pitted dates; process until combined–the mixture will look a little dry. With the motor running about 1 tablespoon of water at a time until mixture is sticky and everything comes together. Depending on if your dates were juicy or dry, you may need less or more water. I needed 5 tablespoons water here. Once the mixture has come together, remove the S blade and fold in chocolate chips. If using regular-sized morsels, feel free to pulse in.
  • Transfer to lined 8×8 pan or silicone pan. Use slightly wet hands to press evenly into pan.
  • Place pan in fridge for 1 hour, or freezer for 30 minutes before cutting into bars. Use large sharp knife and cutting board, cutting bars into 12 or 16 squares. Or roll into balls, press into cookie shape, etc.

Store bars covered in fridge for 2-3 weeks. Or in freezer for about 3 months.

Notes

I use a 12-cup Breville Food Processor. Recipe can be cut in half if you have a smaller bowl to work with. A regular blender will not work with this recipe. I did not test this recipe using a high powered blender (i.e. Vitamix, Blendtec, Wolf Gourmet, etc.) so the process may be slightly different but overall those machines should work for this recipe.

VEGAN IDEAS: You can omit the egg white protein powder and likely sub 1/2 cup of plant protein powder. I can’t vouch for these results as I did not test them this way, and you may need more liquid. Let me know if you try!

Nutrition info provided approximate and calculated using Pineapple Mango Flavor. If making into balls or smaller squares, it will change. Feel free to calculate other flavors using ingredients listed on myfitnesspal(dot)com

PS. If you don’t feel like making your own protein bars at home, I actually do really enjoy RXBARs and all their fun flavors. You can find them here.

    How come there is 2gram difference in protein from original RXBar?

      Hi Susan, I dot not know RXbar’s ratio of ingredients / their recipe formula, so I can’t really say. I just know the ingredients list and how to get the best texture with a homemade version 🙂

    I really like this recipe to make protein bars without peanuts. So hard to find protein rich, low cal versions in stores that don’t use peanuts. After trying to make several batches, only one batch came out with nice solid bars that held together without crumbling. What is the secret to make these bars not fall apart? How can you tell when you have put enough or too much water?

      Hi there, there could be a few factors here. If Medjool dates are not very moist, you may need to add more water. You can also soak your Medjool dates in warm water for 5 minutes and drain before adding to bowl of food processor. If you’ve accidentally over-packed egg white protein, that could be another factor. I think the biggest thing is that if the mixture seems crumbly when you’ve added/processed everything, pulse in 2-3 more tablespoons of water and continue to break the mixture down. When you take a scoop of the mixture, you should be able to press it between your hands and it holds. Hope that helps!

    Can I use pasteurized egg whites instead of the powder?

    Reply

    • Ashley says

      Unfortunately using liquid egg whites would throw off the ratio of wet-to-dry ingredients.

      Hello, try using unflavored collagen peptide powder. Flavor and texture were pretty much the same and the added nutritional benefits are always a plus.

    Hi, I didn’t see it specified anywhere: do the nuts need to be raw or roasted? Thank you!

    Reply

    • Ashley says

      You can use either! Roasted will change the flavor profile only slightly (depending on what fruit/mix ins you use). I think Walnuts taste better Roasted but can go either way with almonds or cashews, if that helps.
