Begin by selecting a microwave-safe mug. In this mug, combine the almond flour, cocoa powder, baking powder, and fine sea salt. Mix these dry ingredients thoroughly until they are fully blended without any lumps.
Once the dry mixture is ready, add your sweetener of choice (honey or maple syrup), the unsweetened applesauce, and the almond milk to the mug. Stir vigorously until you have a smooth batter with no remaining dry pockets.
If you're a chocolate lover, gently fold in the dark chocolate chips at this stage.
Place the mug in the microwave and heat on high for approximately 30-40 seconds. Start with 30 seconds, then check the brownie. It should rise and have a set top, while remaining soft and gooey in the center.
Allow the brownie to cool for at least a minute before indulging, as it will be quite hot straight out of the microwave.
Notes
Savor your mug brownie straight from the mug for a cozy experience, or transfer it to a small plate and top with fresh berries or yogurt for added flavor.
