Fudgy, dense brownies with a crinkly top and crispy edges made in the air fryer. Ready in about 20 minutes with a higher edge-to-center ratio than oven-baked brownies.

Ingredients

Scale
  • 1/2 cup (1 stick) unsalted butter
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 tsp salt
  • 1/4 tsp baking powder
  • Optional: 1/2 cup chocolate chips or chopped walnuts

Instructions

  1. Melt the butter in a microwave-safe bowl in 30-second intervals until fully melted. Stir in the sugar until combined. Add eggs one at a time, stirring well after each, then stir in vanilla.
  2. Sift in the cocoa powder, flour, salt, and baking powder. Fold together until just combined — the batter will be thick. Fold in chocolate chips or nuts if using.
  3. Grease a 7-inch round, 6×6-inch square, or 6-inch springform pan with butter or cooking spray and line the bottom with parchment paper. Pour the batter in and spread evenly.
  4. Preheat your air fryer to 325°F for 3 to 4 minutes. Place the pan in the basket and air fry at 325°F for 18 to 22 minutes.
  5. Check at 18 minutes by inserting a toothpick in the center. For fudgy brownies, pull when the toothpick has a few moist crumbs; for cake-like brownies, pull when the toothpick comes out clean.
  6. Let brownies cool in the pan for at least 10 minutes before cutting to allow the structure to set.

Notes

For fudgy brownies, do not overbake — a toothpick with a few moist crumbs (not wet batter) is the target doneness.

Brownies that seem underdone straight from the fryer often firm up perfectly after 15–20 minutes of cooling.

Boxed brownie mix works great: prepare per package directions and bake at 325°F for 18–22 minutes.

If the top browns too fast, tent a small piece of foil loosely over the pan.
