Ingredients
- Canned pineapple ring: gives the mug cake its signature juicy tropical layer use rings packed in juice for best flavor

- Butter: adds richness and gives that classic upside-down flavor real butter or a quality vegan alternative both work
- Yellow cake mix: offers speed and ensures a fluffy texture pick your favorite brand with a rich vanilla aroma
- Milk: brings the batter together and makes it tender use whole or plant-based milk
Instructions
- Prepare the Mug:
- Place the butter and brown sugar in a microwave-safe mug. Heat in the microwave for about 20 seconds until the butter melts. Swirl gently until the sugar and butter are evenly combined to create a caramel base.
- Add the Pineapple:
- Carefully lay the pineapple ring right into the mug so it sits flat on top of the buttery sugar mixture. Press down lightly so it nestles in and will soak up extra caramel flavor.
- Make the Batter:
- In a separate small bowl stir together the yellow cake mix and milk until very smooth. Make sure there are no lumps and the texture is pourable but not runny.
- Assemble and Cook:
- Pour the cake batter gently over the pineapple in the mug. Microwave on high for one to two minutes. The cake should look risen and firm and the edges should pull away from the mug. Cool for at least one minute before enjoying.
- Finishing Touches:
- Top with whipped cream or a maraschino cherry right before serving for the full tropical sundae effect. A drizzle of coconut cream takes it over the top.
Save The pineapple ring is my favorite part. I loved fishing out that golden fruit bite as a kid when my grandmother baked classic upside-down cake. Making it in a mug brings back those memories without all the effort or dishes.
