Easy Air Fryer Keto Brownies
Jump to...
Introduction
If you’ve been around the blog, you probably know that chocolate is my ultimate weakness. There aren’t many things better than a rich, chocolatey brownie. Am I right, or am I right?
I’ve enjoyed these during quiet afternoons with a book, and at family gatherings too.
These air fryer keto brownies use eight ingredients and bake in two ramekins. The batter combines almond flour and cocoa powder with chopped pecans and sugar-free baking chips for a fudgy brownie with a little crunch.
Why Make Brownies in an Air Fryer?
The air fryer is useful when you want two individual brownies without heating a full-size oven. Preheating it to 350°F allows the ramekins to begin baking as soon as they go into the basket.
Air fryers vary in shape and heating-element placement. Set the ramekins as far from the heat source as your basket safely allows, and use ramekins that the manufacturer identifies as oven-safe.
Key Ingredients
Almond flour supplies the base of the batter, while unsweetened cocoa powder provides the chocolate flavor. Powdered monk fruit sweetener blends into the batter without adding granulated sugar.
Melted butter and one egg bring the batter together. Chopped pecans add texture, and ChocZero baking chips add pockets of chocolate.
How to Make Air Fryer Brownies
Preheat the air fryer to 350°F. Mix the almond flour, baking powder, cocoa powder, and powdered sweetener in a large bowl.
Beat in the egg and melted butter until the batter is evenly combined. Stir in the pecans and baking chips, then divide the batter between two well-greased ramekins.
Place the ramekins in the air fryer and bake for 10 minutes. Let the brownies rest for 5 minutes before serving so they can set.
