Quick Facts

Yield: Serves 1
Prep Time: 5 minutes
Cook Time: 2 minutes
Total Time: 7 minutes

Ingredients

For the Main Dish:

3 tablespoons all-purpose flour
2 tablespoons granulated sugar
1/4 teaspoon baking powder
1/4 teaspoon ground cinnamon
Pinch of salt
3 tablespoons milk
1 tablespoon vegetable oil (or melted butter)
1/4 cup diced apple (about half a small apple)
1/2 teaspoon vanilla extract

For the Sauce / Garnish (optional):

1 tablespoon maple syrup or honey
Powdered sugar for dusting
Vanilla ice cream or whipped cream

How I Make It

Step 1:

Grab a standard-sized microwave-safe mug and toss in the flour, sugar, baking powder, cinnamon, and salt. Give those dry ingredients a quick stir with a fork or small whisk right inside the mug so everything is combined evenly.

Step 2:

Add the milk, oil, and vanilla extract to the mug. Stir everything just until smooth; no worries if you see a few tiny lumps from the flour. The batter should be thick but pourable.

Step 3:

Fold in the diced apple pieces. I like to use crisp apples like Honeycrisp or Granny Smith for a nice tang and crunch that stands up to microwaving.

Step 4:

Pop the mug in the microwave and cook on high for about 90 to 120 seconds. Microwave power varies, so check after 90 seconds; the cake should be set but still moist. Avoid overcooking or it can get rubbery.

Step 5:

Carefully remove the mug (it might be hot!) and let it cool for a minute. The cake will continue to firm up a bit as it cools.

Step 6:

Drizzle with warm maple syrup or honey, dust with powdered sugar, or top with your favorite scoop of vanilla ice cream for a perfect finishing touch.

Variations & Tips

Swap out the diced apple for small chunks of pear or even berries for a fruity twist.
Add a handful of chopped walnuts or pecans inside for extra crunch.
Mix in a pinch of nutmeg or ground ginger along with cinnamon for deeper spice flavor.
Use almond or oat milk to make this dairy-free.
For a richer cake, substitute vegetable oil with melted butter.
If your apples aren’t super sweet, sprinkle in a little extra sugar or a drizzle of honey.

How I Like to Serve It

This mug cake is perfect for a cozy solo dessert night, especially during chilly fall evenings when you crave something warm and cinnamon-scented. It also shines as a quick breakfast treat alongside a hot cup of coffee or tea. Want to impress guests? Serve it with a scoop of vanilla ice cream and a sprinkle of cinnamon—instant mini apple dessert magic!

Notes

Store any leftovers (if you somehow have them!) covered in the fridge and reheat for 20-30 seconds in the microwave.
If you don’t have baking powder, you can try baking soda with a tiny bit of vinegar, but results may vary.

Closing: This Quick Cinnamon Apple Mug Cake is my go-to whenever I want a warm, comforting treat that comes together in minutes—and I know it’ll become one of your favorites too!
