This Peach Mug Cake is a quick, cozy microwave dessert that tastes like a little peach cobbler in a mug. Made with fresh peaches, brown sugar, cinnamon, butter, and pantry staples, it’s warm, fluffy, and ready in about 3 minutes.
Melt ½ tablespoon butter in a 10 to 12 ounce microwave safe mug with 3 to 4 peach slices and ½ tablespoon of brown sugar for 30 seconds.
In a small bowl, whisk ½ tablespoon melted butter with 1 tablespoon brown sugar, vanilla, milk, flour, baking powder, and cinnamon until the ingredients are just combined.
Spoon batter into the mug over the peaches. Do not stir. Place remaining peach slices on top, sprinkle with ½ tablespoon of brown sugar and a extra pinch of cinnamon if desired. Add remaining ½ tablespoon of butter on top.
Microwave on full power for 1 to 2 minutes, depending on your microwave. Begin checking mug cake at about 1 to 1 ½ minutes. Serve with ice cream!
Notes
Mug size: Use a 10- to 12-ounce microwave-safe mug or ramekin to give the cake room to rise.
Microwave timing: Begin checking at 1 minute. The mug cake should look set but still slightly shiny on top. Overcooking can make it tough.
Fresh, canned, or frozen peaches: Fresh peaches are best, but canned or frozen peaches also work. Drain canned peaches well. Thaw and pat frozen peaches dry before using.
Self-rising flour: If using self-rising flour, omit the baking powder.
