Description

This funfetti microwave mug cake delivers light vanilla flavor and colorful sprinkles in a soft, moist texture—all ready in under 5 minutes. It’s joyful, fast, and comforting.


Ingredients

All-purpose flour – 4 tbsp

Baking powder – ¼ tsp

Granulated white sugar – 2 tsp

Fat-free milk (or any milk) – 3 tbsp

Vegetable oil – ½ tbsp

Vanilla extract – ⅛ tsp

Rainbow sprinkles (jimmies preferred) – 1½ tsp


Instructions

1. Add flour, baking powder, and sugar to an 8 oz microwave-safe mug.

2. Pour in milk, oil, and vanilla extract. Mix until smooth and lump-free.

3. Stir in 1 tsp sprinkles gently to avoid color bleeding.

4. Top with the remaining ½ tsp sprinkles.

5. Microwave on high for 1 minute. Check top—it should look set. If needed, microwave 10–15 seconds more.

6. Let cool for 1–2 minutes before eating.

Notes

Use classic rainbow jimmies to prevent color bleeding.

Add a swirl of whipped cream, vanilla glaze, or yogurt for extra flair.

Stir in white chocolate chips for a gooey core.

Boost protein by mixing in 1 tsp of vanilla protein powder.

Enjoy while warm for the best texture and flavor.
