In a microwave-safe mug, combine 2 tablespoons of all-purpose flour, 1 tablespoon of sugar, 1/8 teaspoon of baking powder, and 1/8 teaspoon of salt. Stir these dry ingredients together.
STEP 2
Add 1 tablespoon of milk, 1 tablespoon of vegetable oil, and 1/4 teaspoon of vanilla extract to your mug. Stir until the mixture is smooth and well combined.

Now for the fun part! Place 1-2 pineapple slices on top, and if you’re feeling fancy, pop a maraschino cherry in the center for some extra flair.
STEP 4
Microwave your mug cake on high for about 1 minute to 1 minute 15 seconds, or until the cake is set. Be careful not to overcook it, or you’ll have a dry cake instead of a fluffy one.

Pro Tips for the Best Results
- Experiment: Feel free to get creative with flavors. Try adding a bit of coconut or even some chopped nuts for a little crunch.
- Don’t Overfill: Your mug should only be half full to ensure the cake has room to rise. Trust me; no one enjoys a messy microwave!
- Check for Doneness: Microwaves vary, so keep an eye on your cake as it cooks.
Fun Variations & Topping Ideas
Variations:
- Swap out the pineapple for other fruits like strawberries, peaches, or even chocolate chips for a decadent twist.
- Add a sprinkle of cinnamon or nutmeg for a warm, cozy flavor.
Toppings:
- Whipped cream or vanilla ice cream for a delightful contrast.
- A drizzle of caramel sauce over the top takes it to the next level of deliciousness.
Storing and Reheating
Storing:
Mug cakes are best enjoyed fresh, but you can store leftovers in an airtight container in the fridge for up to a day.
Reheating:
If you have any cake left (lucky you!), microwave it for about 10-15 seconds to revive its fluffy goodness.
Leftover ideas
Can’t finish it all? Use the leftover cake to fill a parfait glass with layers of yogurt and fruits for a quick breakfast or snack!
Frequently Asked Questions (FAQ)
What size mug should I use for a mug cake?
Using a standard-sized mug (about 12 ounces) is ideal. It needs enough room for the cake to rise without overflowing.
Can I make this cake in the oven instead?
Absolutely! Preheat your oven to 350°F (175°C) and bake in a small ramekin for about 15-20 minutes, or until the top is golden and a toothpick comes out clean.
Can I make this vegan?
Yes! Substitute the milk with almond or oat milk and use a plant-based oil to make it fully vegan!
What if I don’t have baking powder?
You can create a substitute by mixing 1/4 teaspoon of baking soda with 1/2 teaspoon of vinegar or lemon juice.
How can I make the cake gluten-free?
Just swap the all-purpose flour for a gluten-free blend. Easy peasy!
