The idea for this pineapple upside down mug cake came to Chef Rita on one of those misty Oregon mornings when nostalgia and sugar cravings hit hard.

But with no time (or oven) to bake the full version, Rita did what she does best: she downsized the joy into a mug.
That same buttery-sweet pineapple flavor, the warm cherry in the center, and a touch of coconut oil to bring in a beachy twist it all came together in one cozy cup.
In her blog post about the Strawberry Mug Cake, Rita talks about how every mug cake she makes carries a story. This one? It’s sunshine in a mug. And the best part? No cake mix, no waiting, and no baking dishes to scrub. Just one spoon, one mug, and one big smile.

Making a pineapple upside down mug cake is simpler than it sounds and a whole lot faster than baking a traditional one. In just a few minutes, you can create a warm, gooey cake with caramelized pineapple and a cherry center that looks as good as it tastes.

In a bowl, whisk together your dry ingredients:
3 tablespoons flour,
1 tablespoon sugar,
1/2 teaspoon baking powder,
and a pinch of salt.
In a separate bowl, mix your wet ingredients:
1 tablespoon plus 1 teaspoon milk,
1 tablespoon plain Greek yogurt,
and 1½ teaspoons room-temperature coconut oil.
Combine the wet and dry mixtures until just smooth. Spoon the batter over the pineapple and microwave the mug in 30-second intervals. A perfectly cooked pineapple upside down mug cake will take about 90 seconds. Look for a domed top and a clean toothpick when inserted in the center.
Let it cool slightly, then carefully invert the mug onto a plate. That first spoonful of warm syrup, pineapple, and vanilla cake is exactly why this pineapple upside down mug cake is a go-to microwave dessert.

Healthier Swaps for a Guilt-Free Mug Cake

Start by replacing the maple syrup with a sugar-free syrup or using unsweetened applesauce for a naturally sweet, lower-sugar alternative. You can also reduce the syrup to 1 tablespoon to cut down on sweetness and calories.
For a lighter batter, use low-fat Greek yogurt or swap it entirely with a plant-based version like almond or soy yogurt. Instead of all-purpose flour, try oat flour or a 1:1 gluten-free blend just expect a slightly softer texture.
Need dairy-free? Swap the milk with almond, coconut, or oat milk. All provide different subtle flavors that pair well with pineapple and coconut.
Looking for fewer carbs? Reduce the flour by 1/2 tablespoon and add 1/2 tablespoon almond flour. This will lighten the carb load while keeping a soft crumb.
Most of these swaps don’t require changing the microwave time but if the batter looks especially thick or dry, add an extra 1/2 teaspoon of liquid before cooking.
