How to make Copycat Reese’s Peanut Butter Protein Bars
Ingredients:
2 cups oat flour (208g), 1/3 cup vanilla protein powder OR almond flour (118g), 3-4 tbsp granulated sweetener of choice, 1/2 cup peanut butter or nut butter of choice (129g), 1/2-1 cup milk of choice, 1/2 cup chocolate (87g)
Directions:
Place all ingredients EXCEPT for chocolate in a bowl and combine well until a dough forms. When adding milk, add 1/4 cup first and mix well and slowly add more milk as needed until you get a firm dough. Scoop a tablespoon of the mixture into your hands and roll into desired shape to make 18 mini bars/eggs. Place on a baking tray lined with baking paper. Using a double boiler or microwave, melt chocolate and set aside. Dip your rolled dough into your melted chocolate and place back onto the lined baking paper. Repeat until all dough has been covered. Place in fridge for 10-15 minutes until chocolate has hardened. Enjoy!

How to store Copycat Reese’s Peanut Butter Protein Bars
Keep them in an airtight container in the refrigerator for up to 10 days. Want to make them last longer for your travel stash? Freeze in a single layer on a tray until firm, then pack in freezer-safe bags for up to 2 months — thaw a minute or two at room temp before biting.
Tips to make Copycat Reese’s Peanut Butter Protein Bars
- Use a firm, thick peanut butter for easier shaping; stir before measuring if oil has separated.
- If dough feels too crumbly, add milk very slowly — you want firm, not sticky.
- Chill the dough for 10 minutes before rolling if it feels too soft.
- Temper the chocolate roughly by letting melted chocolate cool slightly before dipping to avoid a dull finish.
- For neater bars, use a fork to dip and tap off excess chocolate, then smooth edges with a small offset spatula.
Variations (if any)
- Nut-free: swap peanut butter with sunflower seed butter and use protein or oat flour as listed.
- Vegan: use a plant-based protein and non-dairy milk; ensure chocolate is dairy-free.
- Crunchy twist: fold in 2 tbsp crushed pretzels or puffed quinoa for texture.
- Loaded: sprinkle chopped peanuts or cacao nibs on top before the chocolate sets.
FAQs
Q: Can I use regular flour instead of oat flour?
A: Oat flour gives a tender, slightly chewy bar. You can substitute with an equal amount of all-purpose flour, but texture will be a touch denser.
Q: My dough is too sticky — what do I do?
A: Chill it 10–15 minutes, then add a tablespoon more oat flour at a time until manageable. Work quickly so the peanut butter doesn’t warm up.
Q: How much protein does each bar contain?
A: That depends on your protein powder choice. Roughly estimate by adding the grams of protein in your scoop, dividing by the number of bars, and add a few grams from the peanut butter.
Q: Can I make these larger instead of mini bars?
A: Absolutely. Shape into 9 larger bars and adjust chilling time; you might need an extra minute in the fridge for the chocolate to fully set.
Q: Is it better to melt chocolate in the microwave or a double boiler?
A: Both work. Microwave in 20-second bursts, stirring between each. A double boiler gives gentler heat and a more glossy finish.
