INSTRUCTIONS
In a microwave-safe mug, whisk together the protein powder, cocoa powder, sweetener, and baking powder.
Add the egg and milk to the mug.
Stir until the batter is smooth and there are no lumps.
Microwave on high for 60-90 seconds, or until the brownie is cooked through.
Let it cool for a minute before enjoying.
TROUBLESHOOTING
My brownies are too dry
Try adding 1-2 tablespoons more liquid (milk, yogurt, or egg whites). Also ensure you're not over-measuring the protein powder - use the scoop and level method.
They didn't rise properly
Check your baking powder is fresh (test by adding to hot water - it should bubble vigorously). Also, don't overmix the batter as this can deflate the air bubbles.
The texture is rubbery
This usually means too much protein powder or overbaking. Reduce baking time by 2-3 minutes and check doneness with a toothpick.
