Ingredients

• 2 tablespoons vanilla protein powder
• 2 tablespoons almond flour
• 1 tablespoon oat flour
• 1 tablespoon granulated keto sweetener or brown sugar
• ¼ teaspoon baking powder
• Pinch of salt
• 1 tablespoon unsalted butter, melted (or coconut oil)
• 1 tablespoon milk of choice
• ½ teaspoon vanilla extract
• 1 tablespoon chocolate chips (regular or sugar-free)
• Optional: 1 teaspoon chopped walnuts or pecans
• Optional: Flaky sea salt for topping

Equipment Needed

• Small mixing bowl
• Spoon or silicone spatula
• Baking tray
• Parchment paper
• Oven or air fryer

Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C).

Line a small baking tray with parchment paper.

Step 2: Mix the Dry Ingredients

In a small bowl, combine:

• Protein powder
• Almond flour
• Oat flour
• Sweetener
• Baking powder
• Salt

Whisk until evenly mixed.

Step 3: Add the Wet Ingredients

Pour in the melted butter, milk, and vanilla extract.

Mix until a soft cookie dough forms.

If the dough seems dry, add an extra teaspoon of milk.

If it’s too sticky, sprinkle in a little more almond flour.

Step 4: Fold in the Chocolate Chips

Gently stir in the chocolate chips and optional chopped nuts.

Reserve a few chocolate chips to press onto the top before baking.

Step 5: Shape the Cookie

Roll the dough into a ball and flatten it into a thick cookie about ½ inch thick.

Place it on the prepared baking tray.

Top with the remaining chocolate chips and a pinch of flaky sea salt if desired.

Step 6: Bake

Bake for 8–10 minutes, or until the edges are lightly golden while the center remains soft.

Do not overbake, as the cookie will continue to firm up as it cools.

Step 7: Cool

Allow the cookie to cool on the baking tray for 5 minutes before transferring it to a cooling rack.

Enjoy warm for the best soft and gooey texture.

Tips for the Perfect Protein Cookie

• Use a high-quality protein powder with a flavor you enjoy.
• Different protein powders absorb moisture differently, so adjust the milk as needed.
• Avoid overbaking to keep the center soft.
• Let the cookie cool briefly before eating to allow it to set.
• Press extra chocolate chips on top before baking for a bakery-style appearance.

Frequently Asked Questions

Can I use whey or plant-based protein powder?

Yes. Both work well, though plant-based protein powders may require slightly more liquid due to their higher absorbency.

Can I make this gluten-free?

Yes. Use certified gluten-free oat flour or replace it with additional almond flour.

Can I air fry this cookie?

Absolutely. Air fry at 325°F (163°C) for about 6–8 minutes, checking frequently to avoid overcooking.

Why is my cookie dry?

Protein powders vary in texture. If your dough feels dry, add milk one teaspoon at a time until the dough is soft and easy to shape.
