Yield & Timing
Yield: 10–12 cookies
Prep Time: 5 minutes
Bake Time: 10–12 minutes
Total Time: About 15 minutes
Ingredients
Dry Ingredients
- ½ cup vanilla or chocolate protein powder
- ½ cup old-fashioned oats (quick oats also work)
- 2–3 tablespoons coconut sugar or brown sugar (optional, for sweetness)
- ¼ teaspoon baking soda
- Pinch of salt
Wet Ingredients
- 1 cup creamy peanut butter (natural or regular)
- 1 large egg
- 1 teaspoon vanilla extract
- 2 tablespoons milk (almond, oat, or regular — as needed to adjust texture)
Mix-Ins (Optional but recommended)
- ¼ cup chocolate chips
- ¼ cup peanut butter chips
- Chopped nuts (almonds, peanuts, pecans)
- Mini white chocolate chips
Instructions
1. Prepare the Dough
In a medium mixing bowl, stir together:
- peanut butter
- egg
- vanilla extract
- milk
Mix until smooth and creamy.
2. Add Dry Ingredients
Add to the bowl:
- protein powder
- oats
- baking soda
- salt
- sweetener (if using)
Stir until a thick cookie dough forms.
If dough feels too dry, add 1–2 teaspoons of milk at a time.
3. Fold in Mix-Ins
Gently fold in chocolate chips or any add-ins you love.
The dough should be scoopable and slightly sticky.
4. Shape and Bake
Preheat oven to 350°F (175°C).
Line a baking sheet with parchment paper.
Scoop dough into 1–2 tablespoon-sized mounds.
Flatten slightly — these cookies don’t spread much.
Bake 10–12 minutes, until edges are set but centers look soft.
Let cool on the tray for 5 minutes to firm up.
Tips for Best Results
- Don’t overbake — they firm up as they cool.
- Use whey or plant protein; avoid collagen (it won’t hold shape).
- Oats can be pulsed into flour for a smoother cookie texture.
- Add extra chocolate chips on top before baking for a bakery look.
- Natural peanut butter may make cookies softer — add a bit more oats if needed.
