My new chocolate peanut butter protein bars blend creamy peanut butter, honey, oats and cocoa into a chewy bar that’s firm yet soft. Warm peanut butter and melted coconut oil coat the mix before chilling.

This recipe addresses dry, crumbly protein bars, flavorless snacks, and the need for a quick, satisfying post-workout option for busy schedules.

I used to end up with dry, crumbly bars that tasted flat. So, I needed easy protein bars that held together and had a real chocolate kick (especially when the kids pop in after school).

I once forgot to cool the pan so the mixture stuck (lesson learned), now I press the mix with a cup. The chocolate smell in the kitchen makes me grin. Bars are ready in 15 minutes, set after 1 hour chill, ideal for a post-workout snack.

Description

These chocolate peanut butter protein bars blend creamy peanut butter, honey, oats, and cocoa into a chewy bar that’s firm yet soft, perfect for a post-workout snack.


Ingredients

Scale
  • 1 cup peanut butter
  • ½ cup honey
  • ¼ cup coconut oil
  • 1 tsp vanilla extract
  • 2 cups whey protein powder
  • ½ cup collagen peptides
  • 2 cups quick oats
  • ½ cup unsweetened cocoa powder
  • ¼ cup peanut butter powder
  • 2 tbsp flaxseed meal
  • 1 tbsp chia seeds
  • ½ tsp salt
  • 1 tbsp sunflower lecithin granules
  • ½ cup dark chocolate chips
  • 1 tbsp coconut oil

Instructions

  1. Line an 8×8-inch pan with parchment paper, leaving an overhang to make lifting the bars easier once set. For better cling, consider chilling the parchment in the pan before adding the mixture.
  2. In a medium saucepan over low heat, combine 1 cup of peanut butter, ½ cup of honey, and ¼ cup of coconut oil. Stir until fully melted and smooth, taking around 3–4 minutes. Once melted, remove from heat and whisk in 1 tsp of vanilla extract to keep the flavor bright.
  3. In a large bowl, whisk together the following dry ingredients until uniform: 2 cups of whey protein powder, ½ cup of collagen peptides, 2 cups of quick oats, ½ cup of unsweetened cocoa powder, ¼ cup of peanut butter powder, 2 tbsp of flaxseed meal, 1 tbsp of chia seeds, ½ tsp of salt, and 1 tbsp of sunflower lecithin granules. This mix contributes to chewiness and helps prevent a sandy texture.
  4. Pour the warm peanut butter mixture into the dry ingredients. Stir vigorously until every bit of the dry powder is moistened and the mixture holds together when pressed. This is crucial for the bars to maintain their shape without crumbling.
  5. Transfer the mixture to the prepared pan. Using a piece of parchment or the back of a flat measuring cup, press the mix firmly and evenly into the pan. Ensure every corner is filled for consistent shape and texture.
  6. Refrigerate for at least 1 hour, or until fully set. This chilling time not only solidifies the bars but helps the flavors meld together.
  7. While your bars chill, melt ½ cup of dark chocolate chips and 1 tbsp of coconut oil in a microwave-safe bowl. Heat in 20-second bursts, stirring between each until smooth and glossy. Remove while still slightly fluid for easier drizzling.
  8. Once the bars have set, lift them from the pan using the parchment overhang and place them on a wire rack set over parchment paper. Drizzle the melted chocolate evenly over the top, then return to the refrigerator for an additional 15 minutes to allow the drizzle to firm up.
  9. After the drizzle has set, cut the bars into 12 squares using a sharp knife. Wipe the knife between cuts to maintain clean edges.

Notes

  • Choose a natural jar of peanut butter, stir before measuring to ensure a creamy texture. If necessary, almond butter can be used as a substitute.
  • Opt for clear, runny honey to sweeten the bars and keep them moist. Maple syrup works as a vegan alternative.
  • Refined coconut oil offers a neutral taste; melt gently off-heat. Olive oil can be used in the chocolate drizzle.
  • Use a smooth chocolate or unflavored whey protein powder to avoid grit and provide over 20g of protein per bar. Plant-based protein can replace it, but increase lecithin by 1 tsp for better binding.
  • Unflavored type I collagen peptides dissolve well and add protein without altering taste. Skip if unavailable or substitute with extra whey protein.
  • Use certified gluten-free quick oats; they impart chewiness and structure. Oat flour can substitute with the same weight.
  • Prefer Dutch-processed unsweetened cocoa powder for richness. Sifting before mixing prevents lumps and amplifies chocolate flavor without adding sugar.
  • This low-fat peanut butter powder balances the mix’s stickiness while enhancing peanut taste. Use extra protein powder as an alternative if needed.
  • Store flaxseed meal in the fridge for freshness. Both flaxseed and chia seeds contribute fiber and oil to bind the mixture, preventing crumbling. You can substitute extra chia seeds if desired.
  • Sunflower lecithin granules help integrate dry ingredients smoothly, preventing a sandy texture.
  • Choose 70% cacao chocolate chips to contrast and elevate flavor for the bars. If unavailable, chopped dark chocolate bars can replace it in equal volume.
  • Store bars in an airtight container in the refrigerator for up to 10 days; alternatively, freeze for up to 3 months.

Ingredient Notes

  • Peanut butter: Choose a natural jar, stir before measuring, adds creamy texture and protein, binds dry ingredients; swap almond butter if needed.
  • Honey: Opt for clear, runny honey, it sweetens and keeps bars moist without grit; replace with maple syrup for a vegan version.
  • Whey protein powder: Pick a smooth chocolate or unflavored powder, fine grind avoids grit, provides over 20g protein per bar; sub plant-based powder (add lecithin).
  • Quick oats: Use certified gluten-free, check for uniform flakes, adds chew and structure, helps hold moisture; sub oat flour with same weight.
  • Peanut butter powder: Choose low-fat, fine texture, balances stickiness in nut butter base, boosts peanut taste; sub extra protein powder in pinch.
  • Flaxseed meal: Go with golden or brown, store in fridge, adds fiber and oil to bind, prevents crumbles; sub chia seeds extra tablespoon.
  • Chia seeds: Use whole black or white seeds, soak briefly in wet mix, gel adds chewiness and binding; omit if texture offends.
  • Sunflower lecithin granules: Use unflavored, dry-whisk into oats to prevent sandy texture, helps proteins and fats integrate smoothly.
  • Dark chocolate chips: Pick 70% cacao chips, melt gently with coconut oil, drizzle sets with snap and bold contrast; sub chopped bars in equal volume.

Recipe Baking Tips

  1. If bars crumble when pressed, chill mixture 1 hour before cutting to let lecithin bind powders thoroughly and prevent loose crumbs.
  2. When dry pockets appear in mixture, add 1 tablespoon melted coconut oil to help moisten whey and collagen blend and improve cohesion.
  3. For clumps in dry mix, whisk all dry powders in bowl for 30 seconds to break up pockets evenly.
  4. If bars stick to pan, chill lined pan 10 minutes then press parchment edges into corners to prevent tearing when lifting.
  5. For drizzle running off edges, chill bars 1 hour, cool 45 minutes, drizzle ½ cup dark chocolate, refrigerate 15 minutes to set.
