Texture Guide
These peanut butter protein cookies are:
• Thick and soft
• Chewy in the center
• Lightly crisp on the edges
• Not cakey
• Not crumbly
Because they are flourless and protein rich, the dough will be sticky before chilling. That is normal.
Ingredients
1 cup all natural creamy peanut butter
1 cup vanilla protein powder
½ cup coconut sugar
2 eggs
½ tsp baking soda
1 cup mini dark chocolate chips
Ingredient Notes
Peanut Butter
Use natural creamy peanut butter with just peanuts and salt. Avoid added oils for best structure.
Protein Powder
Vanilla protein powder adds sweetness and structure. Whey protein creates a thicker dough. Bone broth protein produces a softer cookie. Plant based protein may require slight moisture adjustment.
Coconut Sugar
Adds caramel like sweetness and helps create golden edges.
Eggs
Provide structure and moisture.
Baking Soda
Helps these peanut butter protein cookies rise slightly and prevents density.
How To Make Peanut Butter Protein Cookies
First, preheat your oven to 350 degrees Fahrenheit. Line a baking sheet with parchment paper.
In a large mixing bowl, add the peanut butter, protein powder, coconut sugar, eggs, and baking soda. Stir until a thick caramel-like dough is formed. If your dough is too runny, add a little more protein powder to thicken it.
Fold in the chocolate chips.
Refrigerate the cookie dough for at least 15 minutes or until it is scoop able. The dough will be very sticky.
Scoop balls of dough onto the lined pan, spacing at least 3 inches apart.
Bake for 10 to 12 minutes, or until the edges are lightly golden but the centers are still gooey.
Remove from the oven. Cool on the pan for 10 minutes before removing.
Protein Powder Adjustment Guide
| Issue | Why It Happens | How To Fix |
|---|---|---|
| Dough too runny | Peanut butter is very natural and loose | Add 1 tablespoon protein powder |
| Dough too thick | Protein powder absorbed excess moisture | Add 1 tablespoon milk |
| Cookies dry after baking | Over baking or too much protein powder | Reduce bake time slightly |
Why Chilling The Dough Matters
Chilling helps:
• Firm up peanut butter fats
• Improve structure
• Reduce spreading
• Create thicker cookies
Skipping this step can result in flatter cookies.
