Instructions

• Step 1

 

In a medium bowl mix together peanut butter, honey, coconut oil, vanilla together until smooth. Add in ground flaxseed meal and protein powder of choice. Use a spoon to mix together until you can’t anymore, then use clean hands to help work together. The batter should be similar to cookie dough.

 

 

step 2

Press into an 8×4 inch pan lined with parchment paper.

• step 3

Make the chocolate layer by adding 2.5 ounces of dark chocolate to a small saucepan and melting until completely smooth. Pour the melted chocolate over the peanut butter layer and tilt the pan so that the chocolate covers the peanut butter layer entirely.

• step 4

Place in the fridge for 30 minutes-1 hour before slicing into 10 bars or squares (either works but I love squares the most). Store covered in the fridge until ready to eat. Bars will keep for up to two weeks.

Notes

*Note: if the batter feels too dry, add ½ – 1 tablespoon of melted virgin coconut oil

For the protein powder: you can use plant based or a whey protein. My personal favorite is Vital Proteins collagen peptides (which is dairy free) but I also love aloha vanilla plant based protein powder for this recipe. Those are the two I highly recommend for flavor and consistency in this recipe.

Step-by-Step Guide to Make Chocolate Peanut Butter Protein Bars Recipe

Step 1: Combine the Wet Ingredients

To begin this chocolate peanut butter protein bars recipe, grab a medium mixing bowl. Add:

• ¾ cup natural peanut butter
• ¼ cup honey
• 1 tablespoon melted coconut oil
• 1 teaspoon vanilla extract

Stir until everything is well blended and smooth. This creamy mix becomes the flavorful base of your bars.

Step 2: Add Protein and Fiber

Now add your dry ingredients:

• ½ cup of protein powder (plain or vanilla)
• ⅓ cup flaxseed meal

Start mixing with a spoon. Once the mixture gets too thick, use your hands to work it into a soft, sticky dough. This part builds the texture that holds the bars together without baking.

Step 3: Press into the Pan

Line a loaf pan (8×4 inches works best) with parchment paper. Firmly press the dough into an even layer across the bottom of the pan. This helps shape the bars before adding the chocolate.

It’s a key step in this chocolate peanut butter protein bars recipe because it keeps the bars from crumbling when you cut them later.

Step 4: Add the Chocolate Layer

Melt about 2.5 oz of dark chocolate using a microwave or stovetop. Spread the melted chocolate evenly over the peanut butter layer. Gently tilt the pan to let it spread across the surface evenly.

Optional: Add a sprinkle of flaky sea salt to balance the sweetness.

Step 5: Chill and Cut

Refrigerate the bars for at least 30 minutes. Once they’ve set, slice into 10 squares or bars.

This chocolate peanut butter protein bars recipe is perfect if you want something quick, homemade, and packed with protein. These bars stay fresh in the fridge for up to two weeks.
