Ingredients

For the Mug Cake:

• 2 tablespoons unsalted butter (or coconut oil)
• 1/4 cup all-purpose flour
• 2 tablespoons sugar
• 1/4 teaspoon baking powder
• Pinch of salt
• 3 tablespoons milk
• 1/4 teaspoon vanilla extract
• Optional: pinch of ground nutmeg (for true donut flavor!)

For the Glaze:

• 3 tablespoons powdered sugar
• 1/2–1 teaspoon milk
• Splash of vanilla extract

Instructions

1. Melt the butter

In a microwave-safe mug (at least 10–12 oz), microwave the butter until melted—about 20–30 seconds.

2. Mix the batter

Add flour, sugar, baking powder, and salt directly into the mug. Stir to combine.
Add milk, vanilla extract, and nutmeg (if using). Stir again until smooth and no lumps remain. The batter will be thick but pourable.

3. Microwave

Microwave on high for 60–90 seconds, depending on your microwave’s power. The cake should rise and look set but still moist on top. Don’t overcook!

Start with 60 seconds and add 10-second bursts if needed. It’s better slightly underdone than overdone!

4. Make the glaze

While the cake cools for a minute, mix powdered sugar, a splash of vanilla, and just enough milk to make a thick, pourable glaze.

5. Glaze and enjoy

Drizzle the glaze over the warm cake in the mug and let it melt into donut-y perfection.

Optional Add-Ins & Variations

• Cinnamon sugar: Mix 1/4 tsp cinnamon into the batter or sprinkle over the glaze.
• Maple glaze: Swap vanilla for maple extract in the glaze.
• Lemon twist: Add 1/4 tsp lemon zest to the batter and glaze with a lemony drizzle.
• Chocolate glaze: Use cocoa powder and a splash of milk in the glaze for a chocolate donut vibe.
• Sprinkles: For a funfetti moment, toss some into the batter or on top.

Tips for Mug Cake Success

• Use a large mug: At least 10 oz so it doesn’t overflow.
• Mix well: Scrape the sides and bottom so no dry flour pockets remain.
• Microwave in short bursts: Every microwave is different—check early and avoid overbaking.
• Let it cool slightly before glazing—it helps the glaze set instead of sliding right off.

FAQ

Can I make it vegan?
Yes! Use plant-based butter or oil, almond milk, and your favorite plant-based glaze.

Can I double the recipe?
You can, but use two mugs and microwave separately for best results.

Can I make it ahead?
Mug cakes are best fresh, but you can pre-mix the dry ingredients in the mug for later.

Why did my cake turn rubbery?
It was likely overcooked—next time, microwave for less time or add a splash more milk to the batter.

Can I use almond or oat flour?
Almond flour will make it denser and more moist; oat flour works but might need more milk to loosen the batter.
