Quick Facts

• Yield: Serves 1
• Prep Time: 3 minutes
• Cook Time: 1 minute
• Total Time: 4 minutes

Ingredients

For the Main Dish:

• 4 tbsp all-purpose flour
• 2 tbsp granulated sugar
• 1/4 tsp baking powder
• 3 tbsp milk
• 1 tbsp vegetable oil
• 1/2 tsp vanilla extract
• 2 tbsp rainbow sprinkles (funfetti-style)
• Pinch of salt

How I Make It

Step 1:

Grab your favorite microwave-safe mug and add 4 tablespoons of flour, 2 tablespoons sugar, 1/4 teaspoon baking powder, and a pinch of salt. Give it a quick whisk or stir with a fork to combine all the dry ingredients evenly.

Step 2:

Next, pour in 3 tablespoons milk, 1 tablespoon vegetable oil, and 1/2 teaspoon vanilla extract. Mix everything well until you have a smooth batter without lumps. It should be thick but pourable.

Step 3:

Stir in the 2 tablespoons of rainbow sprinkles. These little bursts of color not only make the cake look joyful but also add tiny, melty pockets of sugary fun.

Step 4:

Pop your mug into the microwave and cook on high for about 60 seconds. Watch it rise but don’t let it overflow. Every microwave is different, so check it at 50 seconds if you’re unsure.

Step 5:

Carefully remove the mug (it can be hot!) and let your mug cake cool for a minute or two; this helps the edges set without steaming the center too much.

Step 6:

If you want, top with a dollop of whipped cream or a scoop of vanilla ice cream. Then, dig in with a spoon and enjoy that fluffy, soft crumb full of colorful sprinkles!

Variations & Tips

• Swap regular milk for almond or oat milk for a dairy-free version.
• Add a pinch of cinnamon or a drop of almond extract for a flavor twist.
• Use mini chocolate chips instead of sprinkles for a chocolaty surprise.
• If your microwave is super powerful, reduce cooking time to 45 seconds to avoid dryness.
• For an extra gooey center, poke a small hole in the cake after 30 seconds and insert a cube of chocolate, then continue cooking.

How I Like to Serve It

This funfetti mug cake feels perfect on cozy weekend mornings or as a quick party dessert when you need a personal treat. It’s also a charming little surprise for a birthday or a sweet way to brighten up a stressful workday. Pair it with your favorite cup of coffee or tea to turn an ordinary moment into something joyful.

Notes

• Store any leftovers (if you dare) covered in the fridge for up to 24 hours, then microwave briefly before enjoying again.
• Use a large mug to give the batter room to rise and avoid spills in the microwave.

Closing: This microwave funfetti mug cake is a tiny, colorful burst of happiness that always hits the spot when you need a quick and cheerful treat.
