Ingredients

For the Chocolate Cookie Base

  • 1 cup super fine almond flour

  • ¼ cup unsweetened cocoa powder

  • ⅓ cup granulated erythritol (or your favorite keto-friendly sweetener)

  • 1 teaspoon baking powder

  • ¼ teaspoon salt

  • 1 large egg (room temperature)

  • 3 tablespoons melted butter (or coconut oil for dairy-free)

  • ½ teaspoon vanilla extract

For the Peanut Butter Swirl

  • ¼ cup natural, no-sugar-added peanut butter (creamy works best)

  • 1 tablespoon powdered erythritol (optional, for sweetness)

  • ½ teaspoon vanilla extract


Instructions

1. Preheat Your Air Fryer

Preheat your air fryer to 320°F (160°C) for 3-5 minutes. Preheating ensures the cookies start cooking immediately, giving them a nice, even bake and a slightly crisp edge.

2. Prepare the Peanut Butter Swirl

In a small, microwave-safe bowl, combine the natural peanut butter, powdered erythritol, and vanilla extract. Microwave for 15-20 seconds until it becomes loose and stirrable. Set it aside. This will make it easy to swirl into the cookie dough.

3. Mix the Dry Ingredients

In a medium mixing bowl, whisk together the almond flour, unsweetened cocoa powder, granulated erythritol, baking powder, and salt. Ensure there are no clumps of cocoa powder for a consistent chocolate flavor.

4. Combine the Wet Ingredients

In a separate small bowl, whisk the melted butter, egg, and vanilla extract until combined.

5. Form the Dough

Pour the wet ingredients into the dry ingredients. Stir with a spatula until a thick, cohesive dough forms. The dough will be soft but should hold its shape when pressed.

6. Shape the Cookies

Scoop out about 1.5 tablespoons of dough and roll it into a ball. Place the ball on a piece of parchment paper cut to fit your air fryer basket. Gently flatten the ball with your fingers or the bottom of a glass to about ½-inch thickness. Repeat with the remaining dough, leaving at least 1 inch of space between each cookie for air circulation. You will likely need to cook in batches.

7. Add the Peanut Butter Swirl

Using a small spoon or the tip of a butter knife, take a small dollop of the softened peanut butter mixture and place it on top of each cookie. Gently swirl it into the surface of the dough with a toothpick or the tip of the knife. Be careful not to over-swirl, as you want distinct pockets of peanut butter.

8. Air Fry

Carefully transfer the parchment paper with the cookies into the preheated air fryer basket. Air fry at 320°F (160°C) for 8-10 minutes.

Cook Time Guide:

  • 8 minutes: A softer, chewier cookie.

  • 10 minutes: A firmer cookie with a crispier edge.

9. Cool

The cookies will be very soft when they come out of the air fryer. Do not attempt to move them immediately. Let them cool on the parchment paper for at least 10-15 minutes. As they cool, they will firm up to the perfect cookie texture.


Recipe Notes & Tips for Success

  • Almond Flour is Key: Do not substitute coconut flour 1:1. Coconut flour is much more absorbent and will result in a dry, crumbly cookie. If you only have coconut flour, look for a specific recipe designed for it.

  • Parchment Paper is Essential: Using parchment paper prevents the cookies from sticking to the air fryer basket and makes cleanup effortless. It also helps prevent the bottoms from burning.

  • Don’t Overcrowd: Air fryers work by circulating hot air. Overcrowding the basket will lead to unevenly baked cookies. Cook in batches for the best results.

  • Sweetener Choices: Granulated erythritol or monk fruit sweetener works best for structure. Allulose will yield a softer, more traditional cookie texture but may brown more quickly.

  • Storage: Store cookies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. They also freeze beautifully for up to 3 months.
