Why You’ll Love This Recipe

• Ready in minutes
• Made with pantry staples
• No oven required
• Perfect single serving
• Soft, fluffy texture
• Easy to customize

Ingredients

• 5 tablespoons all-purpose flour
• 2 tablespoons sugar
• ¼ teaspoon baking powder
• Pinch of salt
• 1 egg yolk
• 2 tablespoons melted butter
• 3 tablespoons milk
• 1 teaspoon vanilla extract

Instructions

Step 1: Mix Dry Ingredients

In a microwave-safe mug (12–14 oz), add the flour, sugar, baking powder, and salt. Stir until well combined.

Step 2: Add Wet Ingredients

Add the egg yolk, melted butter, milk, and vanilla extract to the mug.

Stir well until the batter is smooth and no dry flour remains. Make sure to scrape the bottom of the mug so everything is fully mixed.

Step 3: Microwave

Microwave the mug cake on HIGH for 60–90 seconds, depending on your microwave.

The cake is done when it has risen and the center looks set. Avoid overcooking, as mug cakes can dry out quickly.

Step 4: Cool Slightly and Enjoy

Let the mug cake cool for 1–2 minutes before eating. The cake will continue to set as it cools.

Enjoy straight from the mug or add your favorite toppings.

• Drizzle with chocolate or caramel sauce

Tips for Success

• Use a large mug to prevent overflow
• Mix thoroughly to avoid flour pockets
• Start with less cook time and add more if needed

Jennie’s Thoughts

This vanilla mug cake is one of my favorite little desserts to make when I want something sweet without committing to a full recipe. There’s something comforting about mixing everything right in a mug and having a warm cake ready in just a few minutes.

Using just the egg yolk keeps the cake soft and tender instead of spongy, which is exactly what you want in a mug cake. I also love how simple the vanilla flavor is—it makes this recipe easy to customize depending on what you’re craving.

Some days I eat it plain right out of the mug, and other days I’ll add a little frosting, whipped cream, or even a few chocolate chips on top. It’s the kind of recipe you can make again and again without getting tired of it.

This Easy Vanilla Mug Cake is proof that you don’t need a full recipe or a lot of time to enjoy a homemade dessert. With simple ingredients and just a microwave, you can have a warm, fluffy cake whenever the craving hits.

Whether you enjoy it plain or dressed up, this quick vanilla mug cake is always a good idea.
