Description
Make these simple peanut butter protein bars with oats, honey, and your fave protein powder and prepare to be forever changed! Truly the best tasting and best texture protein bar (and I've tried a lot). Tested with collagen peptides, whey protein powder, and plant protein powder. Amazing right out of the freezer and ideal for meal prep!
Ingredients
- 1 cup oat flour (old-fashioned oats ground into a fine powder in the blender)
- 2 tbsp ground flaxseed
- 1/2 cup vanilla protein powder (vanilla collagen is my favorite), see notes*
- 1/4 tsp fine sea salt
- 1/2 cup natural salted peanut butter
- 1/4 cup honey
- 1 tsp vanilla extract
- Optional: flakey salt, mini chocolate chips or melted chocolate for drizzling
Instructions
- Line a standard 9x5in loaf pan with parchment paper. Place oat flour, flax, protein powder, and salt in a mixing bowl. Whisk until combine.
- Add peanut butter, honey, and vanilla (and 1 tbsp coconut oil if using vegan protein per note below). Use a spoon (I like to use my hands here!) to mix until fully combined. Taste and make sure the texture is right (you can also add a splash of milk if needed).
- Dump mixture into pan and press down very firmly until it's smooth and flat. Sprinkle with flaky salt and press in a handful of chocolate chips if desired.
- Freeze for at least 30 minutes before cutting into 8 bars. I like eating these right out of the freezer! You can store them there (I use this silicone bag) or in the fridge.
Notes
*I tested this recipe with Rootz vanilla collagen, Vega Vanilla (vegan pea protein), and Ascent vanilla whey protein and it works well with all of them, but the collagen had my favorite texture. If using vegan protein, add 1 tbsp melted coconut oil to the mixture for moisture and use maple syrup instead of honey. If using unflavored protein, add an extra tsp vanilla (2 tsp total).
