Add the butter to a 4 oz ramekin. Place it in an air fryer basket and cook at 350 F for 2 minutes or until melted (length of time here could be longer if you start with cold butter versus room temperature).
Step 2
You do not need to remove the ramekin from the basket as it will be hot. Once butter is melted, add in the almond flour, granulated sweetener, egg yolk, and vanilla extract. Mix well.
Step 3
Next, top the mixture with chocolate chips.
Step 4
Bake in the air fryer at 350 F for 6-7 minutes or until golden brown on top. Serve immediately!
