Prep Time15 minutes mins
Chill Time30 minutes mins
Total Time45 minutes mins
Servings: 12
- 1 ½ cup rolled oats
- ½ cup chocolate protein powder
- ¾ cup creamy peanut butter
- ⅓ cup Reese’s Pieces plus extra for topping if desired
- 2 tbsp mini chocolate chips
- 4.5 tbsp honey
- 4.5 tbsp water plus extra if/as needed
Line an 8×8 baking pan with parchment paper or wax paper so the bars don’t stick.
Add all of the ingredients to a large bowl and mix until well combined. If the mixture feels too dry or crumbly, add a little water, one teaspoon at a time, until it comes together.
Press the mixture evenly into the prepared pan.
Cover with foil or plastic wrap and chill until set — either freeze for at least 30 minutes or refrigerate for at least 60 minutes.
Once firm, lift the bars out of the pan by grabbing the parchment or wax paper and transferring the whole block to a cutting board.
Cut into 12 bars.
Let the bars thaw slightly so they’re pliable, then gently press extra Reese’s Pieces onto the tops.
Store the bars in the refrigerator or freezer and enjoy.
