Peanut Butter Cupcake Swirl

Line the muffin tins with cupcake liners and set aside.

Cream together the butter, sugar, and peanut butter using a whisk or an electric mixer. Then, add the egg, milk and vanilla extract. Mix until homogenous. Finally, add the rest of dry ingredients and mix until well combine.

Scoop the batter into the liners about 2/3 full. Then, use a spoon to drop about 1/2 teaspoon of Nutella into the center of the cupcake. Insert a toothpick into the center of the Nutella and create a swirl by making circles in the batter.

Air fry at 300F (150C) for about 12-14 minutes. Insert a toothpick to test. When the toothpick comes out clean, then the cup cake is cooked through.
