There’s nothing like waking up to a warm sweet treat but you don’t always want to bake a whole batch of donuts This mug cake brings that iconic glazed donut goodness right to your kitchen in a few quick minutes thanks to your microwave It’s cozy and super low effort

When I first made this mug cake I had a donut craving before heading to work I was shocked at how much this mug cake tasted like the donuts I grew up loving And best of all barely any mess

Dreamy Ingredients

  • AllPurpose Flour: the base that gives your cake a soft bounce Regular unbleached flour works best If you can give it a sift for a nicer crumb
  • Sugar: that sweet classic taste Fine cane sugar gives the smoothest bite
  • Baking Powder: this makes the cake puff up light and cook evenly Use fresh baking powder for fluffiest results
  • Milk: adds moisture and flavor Whole milk gives extra richness but any type is fine
  • Melted Butter: makes the mug cake rich and tender Choose real butter if you can skip the margarine
  • Vanilla Extract: brings cozy bakery vibes Pure vanilla really boosts the flavor
  • Powdered Sugar: the magic ingredient for the shiny sweet glaze Sifting keeps things smooth
  • Extra Milk: loosens up the glaze Pick whatever milk you used before
  • Extra Vanilla: ties the glaze together with that bakery scent Pure extract tastes the best

Step-by-Step Directions

Make Your Glaze:
In a tiny bowl stir a tablespoon of powdered sugar with a teaspoon of milk plus a splash of vanilla until nice and smooth Pour the glaze however you like onto the warm cake so it really soaks in
Cook in Microwave:
Put the mug in the microwave on high power Start with a minute and a half Watch as it cooks The top should look set but feel moist to the touch Need longer Go in ten second bursts
Fill the Mug:
Pour your mixed batter into a mug big enough to hold at least twelve ounces Leave some space at the top so there’s no overflow
Add Your Dry Ingredients:
Tip in a quarter cup of all purpose flour plus a quarter teaspoon baking powder Gently mix till you get a smooth batter Don’t stir too much or the cake will turn dense
Mix Liquid Stuff:
Whisk three tablespoons of milk three tablespoons melted butter two tablespoons sugar and half a teaspoon vanilla in a small bowl Mix till creamy and the sugar’s starting to blend in This helps keep it moist and flavorful

I especially love swirling the glaze around while my mug cake’s still warm It soaks in just like the donuts at my favorite bakery My kid always wants to clean out the bowl afterward

Storing Leftovers

This treat is best hot right out of the microwave Let it cool cover it with plastic and pop it in the fridge if you’ve got some left Try to eat it within a day Just toss it back in the microwave for a few seconds and drizzle over some extra glaze

Switch Things Up

No butter Handy coconut oil or just use mild veggie oil to skip dairy Almond milk or oat milk work perfectly too If you can grab real vanilla it adds way more flavor than the fake stuff

Fun Ways to Serve

Want to dress it up Sprinkle on some cinnamon sugar or fun sprinkles before you glaze If it’s dessert time scoop in some vanilla ice cream or add strawberries on the side

Frequently Asked Questions

→ How do I prevent the mug cake from overflowing?

Don’t fill your mug all the way up—give the batter some space to climb as it cooks so it won’t spill out in your microwave.

→ What texture should I expect from the mug cake?

This treat should turn out soft and airy, kinda like a fluffy donut, and the glaze makes a sweet, sticky topping.

→ Can I substitute the all-purpose flour?

Sure thing, whole wheat or gluten-free flour will work too, but expect a slightly different result in texture.

→ How do I know when the mug cake is done?

The top shouldn’t look wet and should bounce back if tapped. If the middle’s not cooked, pop it back in for a bit.

→ Can I add toppings to this mug cake?

Totally! After microwaving, toss on some cinnamon, rainbow sprinkles, or a bit more glaze to jazz it up.

Ingredients

→ Mug Cake Base

01 2.5 milliliters vanilla extract
02 42 grams unsalted butter, melted
03 45 milliliters whole milk
04 1.25 grams baking powder
05 25 grams granulated sugar
06 32 grams all-purpose flour

→ Sugar Glaze

07 1.25 milliliters vanilla extract
08 5 milliliters whole milk
09 8 grams powdered sugar

Instructions

Step 01

Grab a bowl and whisk the milk, the melted butter, sugar, and vanilla all together till the mix looks smooth and blended.

Step 02

Now add the baking powder and flour to your wet mix. Stir away till you can’t see any more dry spots and the batter looks good and even.

Step 03

Scoop the batter into a big mug that’s safe for the microwave, but only fill it halfway or you’ll have a mess when it cooks.

Step 04

Pop the mug in the microwave and cook it on high for about 1 or 2 minutes. The cake should puff up and the top shouldn’t look wet any more.

Step 05

In a little bowl, mix together your powdered sugar, some milk, and just a bit of vanilla until you have a nice runny icing.

Step 06

Pour that glaze right over the steaming mug cake and you’re good to go.

Notes

  1. Let your mug cake hang out for a minute before you pour on the glaze so it sets up just right.
