How to Make It
In a microwave-safe mug, mix the flour, sugar, and baking powder.
Add in the vanilla extract, milk, lemon juice, and melted butter.
Stir until well combined.
Gently fold in the blueberries.
Microwave on high for about 1-1.5 minutes.
Let it cool for a minute before digging in.
Serve
This mug cake is best served warm, right from the mug. Grab a spoon and enjoy the warm, gooey center filled with sweet blueberries and a hint of lemon.
