In a 12-ounce mug, add butter and brown sugar and microwave until the butter melts. Stir together.
Place the pineapple slice in the bottom of the mug and top with a cherry.
In a small bowl, add the flour, sugar, baking powder, and salt. Stir in the milk and vanilla extract until smooth. I like to use a whisk. Pour the batter over the pineapple in the mug.
Microwave on high for 1 minute to 1 ½ minutes (90 seconds). The timing of the mug cake will depend on the size of your mug and your microwave. Be careful not to over-microwave. The top will be just set. In my 1000-watt microwave, it is perfect at 1 minute and 10 seconds.
Using a knife, gently release the sides of the mug cake and carefully invert the cake onto a small plate or enjoy it in the mug. Serve immediately as is or with vanilla ice cream. Enjoy!

Sugar: You will notice we use a combination of brown sugar and granulated sugar in this mug cake. The brown sugar brings delicious flavor to the top of the mug cake (like a traditional upside-down cake), and the granulated sugar in the cake helps produce a lighter, fluffier texture. However, in mug cakes, as you likely know, they are not as light and fluffy as traditional sponge cakes.
Can I make this gluten-free? Yes! A 1:1 gluten-free flour blend will work well in place of all-purpose flour.
What size mug should I use? Choose a 12–14 oz microwave-safe mug to give the cake space to rise without spilling.
How do I know when the cake is done? The top should look set and spring back when gently touched. If it looks wet in the center, microwave in 10-second bursts.
Can I store leftovers? Mug cakes are best enjoyed fresh, but if needed, you can loosely cover and refrigerate for up to 1 day. Reheat gently.
