Prep: Preheat oven to 350°F (176°C). Grease an 8x8-inch baking pan.
Blend: In a food processor, combine all ingredients except chocolate chips until smooth.
Chips: Stir in chocolate chips.
Bake: Transfer batter to your prepared pan and bake for 30 to 40 minutes, or until the edges pull away from the sides and the top is shiny and a bit crinkly. A toothpick inserted may still come out with moist crumbs.
Serve: Allow brownies to cool before cutting.
Notes
Storage: I keep these in the fridge in an airtight container, where they stay good for up to 7 days. That's what makes them my treat for the week.They also freeze well. Slice them first, then store the squares in a freezer bag or airtight container. To thaw, move them to the fridge overnight, or pop a square straight from the freezer into the air fryer for a few minutes until warm.
