Light and airy, just like a classic sponge should be. I’m so excited to share this quick, foolproof recipe with you because there’s nothing better than a warm cake that’s ready before you can say “dessert!” Let’s jump in and make your microwave your new best baking buddy.

Quick Facts

• Yield: Serves 4
• Prep Time: 5 minutes
• Cook Time: 3 minutes
• Total Time: 8 minutes

Ingredients

For the Main Dish:

• 1 cup all-purpose flour
• 1/2 cup granulated sugar
• 1 tsp baking powder
• 1/4 tsp salt
• 2 large eggs
• 1/2 cup whole milk
• 1/4 cup vegetable oil
• 2 tsp vanilla extract

How I Make It

Step 1:

First, in a medium bowl, whisk together the flour, sugar, baking powder, and salt to evenly combine all the dry ingredients. This helps the cake rise beautifully in the microwave.

Step 2:

In another bowl, beat the eggs, milk, vegetable oil, and vanilla extract until smooth and slightly frothy. This mixture is your flavor and moisture base—don’t skip the vanilla! It makes the kitchen smell heavenly.

Step 3:

Slowly add the wet ingredients to the dry, stirring gently until just combined. Avoid overmixing to keep the sponge light and tender. The batter should be smooth but not runny.

Step 4:

Pour the batter into a microwave-safe, greased 8-inch round cake pan or silicone mold. Smooth the top with a spatula so it cooks evenly.

Step 5:

Microwave on high for about 2 1/2 to 3 minutes. The cake is done when it springs back gently when touched and a toothpick inserted into the center comes out clean. Microwave strengths vary, so keep a close eye after 2 minutes!

Step 6:

Let the cake rest for a couple of minutes before carefully removing it from the pan. Serve warm or at room temperature—plain, dusted with powdered sugar, or topped with fresh berries and whipped cream. Yum!

Variations & Tips

• Swap milk with almond or oat milk for a dairy-free version.
• Add 1/4 cup of cocoa powder to the dry ingredients for a chocolate twist.
• Mix in a handful of chocolate chips or chopped nuts for added texture.
• If the cake is slightly dense, try increasing the baking powder to 1 1/4 tsp for extra lift.
• Microwave baking times vary—start with 2 1/2 minutes, then add 15-second bursts if needed.
• For a crispier top, briefly broil in the oven for 1-2 minutes after microwaving.

How I Like to Serve It

This vanilla sponge is an everyday treat! During summer, I love pairing it with fresh peaches and a dollop of whipped cream. In cooler months, warm it up and drizzle with luscious caramel sauce. It’s simple, versatile, and perfect for impromptu celebrations or cozy nights in.

Notes

• Store leftover cake in an airtight container at room temperature for up to 2 days.
• Reheat briefly in the microwave (about 10 seconds) to bring back that soft, warm feeling.

Closing: Believe me, once you try this microwave vanilla sponge cake, you’ll always have a quick, delicious fix for when the sweet tooth strikes.
