Quick Facts

Yield: Serves 1 (single cake) or 4–6 (mini cakes)
Prep Time: 3 minutes
Cook Time: 2 minutes
Total Time: 5 minutes

Ingredients

For the Main Dish:

4 tbsp all-purpose flour
3 tbsp granulated sugar
1/4 tsp baking powder
Pinch of salt
3 tbsp milk
2 tbsp vegetable oil
1/4 tsp vanilla extract
2 tbsp rainbow sprinkles (plus extra for topping)

For the Frosting / Garnish (optional):

2 tbsp cream cheese, softened
1 tbsp powdered sugar
1/2 tsp vanilla extract
Extra sprinkles for garnish

How I Make It

Step 1:

Grab a microwave-safe mug or a small bowl. In it, whisk together the flour, sugar, baking powder, and salt until well combined—this dry mix forms the base of your cake.

Step 2:

Add in the milk, vegetable oil, and vanilla extract. Gently stir until you get a smooth batter, making sure there aren’t any clumps hiding at the bottom or edges.

Step 3:

Sprinkle in the rainbow sprinkles and fold them in quickly; don’t overmix, or the colors might bleed. The batter should look dotted with bright, cheerful specks now.

Step 4:

Pop your mug or bowl into the microwave and cook on high for about 90 seconds to 2 minutes. Your cake will rise and puff up like magic. If it’s still a bit wet on top, nuke it in additional 10-second bursts—but be careful not to overcook, or it will dry out.

Step 5 (Optional Frosting):

While the cake cools for a minute or two, mix together the cream cheese, powdered sugar, and vanilla until silky smooth. This frosting adds a tangy, creamy touch that’s just irresistible.

Step 6:

Top your warm cake with a generous dollop of frosting (if using) and an extra sprinkle of cute, colorful bits. Grab a spoon and dig right in—ooey, gooey, sprinkle-studded happiness!

Variations & Tips

Use almond or oat milk for a dairy-free version that’s still super moist.
Swap sprinkles for chocolate chips or chopped berries for a twist.
Add a pinch of cinnamon or lemon zest to the batter for an extra flavor boost.
If you want a bigger cake, double the ingredients and use a microwave-safe ramekin—just increase cook time by 30–45 seconds.
Keep an eye on microwave power levels, as all ovens differ; adjusting time slightly can help avoid a rubbery cake.

How I Like to Serve It

This cute, speedy cake is perfect for birthdays anytime, especially when you need a quick celebration fix. Serve it with a cold glass of milk or a scoop of vanilla ice cream in the summer. For chilly evenings, a warm mug of hot cocoa alongside makes it feel extra cozy. Kids and adults alike love how fun and festive it looks—bonus points for instant smiles!

Notes

Store leftover frosting in the fridge for up to 2 days, but this cake is best enjoyed fresh.
If you want to reheat, microwave for 10–15 seconds just until warm; don’t overdo it or it’ll dry out.

Closing: Honestly, this 5-Minute Funfetti Birthday Cake is my go-to for instant celebration vibes—fast, fun, and sprinkled with joy every single time.
