Quick Facts

Yield: Serves 1
Prep Time: 2 minutes
Cook Time: 3 minutes
Total Time: 5 minutes

Ingredients

For the Main Dish:

4 tbsp all-purpose flour
2 tbsp granulated sugar
1/4 tsp baking powder
Pinch of salt
3 tbsp milk
1 tbsp melted butter
1 tbsp caramel sauce (plus extra for drizzling)
1/4 tsp vanilla extract

How I Make It

Step 1:

Grab a microwave-safe mug and whisk together the flour, sugar, baking powder, and salt until they’re well combined. This dry mix is the base that makes sure the cake rises nicely and doesn’t turn soggy.

Step 2:

Pour in the milk, melted butter, caramel sauce, and vanilla extract. Stir everything together until the batter is smooth and shiny with that inviting caramel color showing through.

Step 3:

Pop the mug into the microwave and cook on high for about 90 seconds to 2 minutes. Keep an eye—or better yet, listen! The cake should puff up and look set on top but still moist when you gently touch it.

Step 4:

Carefully remove the mug (it’ll be hot, so use a kitchen towel or mitt). Let it sit for a minute to finish steaming inside.

Step 5:

Drizzle a little extra caramel sauce over the top—it adds a sticky, glossy finish and amps up the sweet, buttery goodness.

Step 6:

Grab a spoon and dig in while it’s warm, soft, and perfectly comforting.

Variations & Tips

For a nutty crunch, sprinkle chopped pecans or walnuts on top before microwaving.
Swap milk for almond or oat milk for a dairy-free version.
Add a pinch of cinnamon or a little sea salt to the batter to deepen the flavor.
If the cake is a bit dense, reduce cooking time slightly to keep it more moist.
Try mini chocolate chips mixed into the batter for extra gooey pockets.

How I Like to Serve It

This caramel mug cake shines as a solo treat during a chilly evening wrapped in your favorite blanket. It also makes a cute dessert when you have unexpected guests—because who can say no to a quick, warm cake? For a decadent touch, serve with a scoop of vanilla ice cream or a dollop of whipped cream right on top.

Notes

Store any leftovers in the fridge, but honestly, it’s best eaten fresh.
Reheat gently in the microwave for 20-30 seconds if needed, but watch closely to avoid overcooking.

Closing: Whenever I need a quick, cozy boost, this mug cake has my back—simple, fast, and oh-so-yummy every single time.
