How long do I microwave a cinnamon roll mug cake?

About 70–90 seconds in a 1000-watt microwave. Start checking at 60 seconds and stop as soon as the top is set and springs back — overcooking is what makes mug cakes rubbery.

Can I make it without eggs?

This recipe is already egg-free — the small size sets fine without one, which also makes it quick and low-waste.

Why is my mug cake dense?

Usually overcooking or unmixed flour at the bottom. Whisk the batter smooth and cook just until set.

The quick answer

A cinnamon roll mug cake is a single-serving batter mixed and cooked in a mug in the microwave (about 60–90 seconds), with a cinnamon-sugar swirl and cream cheese glaze. Don't overcook it — pull it as soon as the top springs back, since mug cakes turn rubbery fast.

This is the answer to a cinnamon roll craving at 10 p.m. with zero patience. You stir a simple batter right in a mug, ripple a spoonful of cinnamon-sugar-butter through it, and microwave it for about a minute and a half. What comes out is a warm, tender single-serving cake with a gooey cinnamon swirl — spoon a little cream cheese glaze on top and you've got dessert for one without turning on the oven or washing a single bowl.

Instructions

In a 12-oz microwave-safe mug, whisk the flour, sugar, baking powder, and salt with a fork.
Dry ingredients are evenly blended.
Stir in the milk, melted butter, and vanilla until smooth with no dry pockets at the bottom.
Batter is smooth and thick.
Mix the swirl butter, brown sugar, and cinnamon in a small dish, then spoon it over the batter and drag a toothpick through once or twice.
A dark cinnamon ribbon sits in the batter.
Microwave on high about 70–90 seconds, until the top springs back and looks set. Start checking at 60 seconds.
Top is set and springs back; not wet in the center.
Let it rest a couple of minutes. Stir the glaze until pourable and spoon it over the top.
Glaze melts slightly into the warm cake.

Make ahead, store & reheat

Make ahead: Mix the dry ingredients in the mug ahead of time so it's grab-and-go; add the wet ingredients and microwave when you want it. Best eaten right away, warm.
Storage: Really meant to be eaten immediately. Leftovers can be covered and refrigerated a day but will firm up.
Reheating: Microwave 10–15 seconds to soften again before eating.
Freezing: Not recommended — mug cakes are a make-and-eat treat.

Substitutions

Any milk, including oat or almond instead of milk
A drizzle of vanilla glaze or a pat of butter and cinnamon sugar instead of cream cheese glaze

Troubleshooting

Mug cake turned rubbery or dry: It overcooked — microwaves vary, so start at 60 seconds and stop the moment the top is set. Even 15 extra seconds toughens it.
Center is wet or gummy: Cook in 10-second bursts until just set, and make sure you fully stirred the batter so there are no dense flour pockets.
It overflowed the mug: Use a roomy 12-oz (or larger) mug — the cake puffs a lot as it cooks and settles back down after.
