How to make a mug cake with 3 ingredients?

You can whip up a basic mug cake with just three ingredients—usually a combination of self-rising flour, milk, and a sweetener like Nutella or peanut butter. While it’s quick, a full coffee cake mug cake recipe uses a few more pantry staples to create that signature soft texture and cinnamon-sugar flavor. The extra steps are worth it for that rich, buttery crumb and topping.

Why do my mug cakes never work?

Most mug cake fails come down to overcooking or incorrect measurements. Microwaves vary in power, so cooking for too long can make the texture rubbery. Also, too much flour or not enough fat (like butter) will dry it out. This coffee cake mug cake recipe keeps those elements balanced, giving you consistent, fluffy results if you follow the measurements closely.

What makes coffee cake taste like coffee cake?

Despite the name, coffee cake rarely contains coffee. It’s the brown sugar, cinnamon, and buttery crumb topping that give coffee cake its flavor profile. In a coffee cake mug cake recipe , those elements are scaled down perfectly—especially the spiced crumble, which crisps up in the microwave to mimic that classic texture.

Why did my mug cake turn out rubbery?

Rubbery mug cakes usually mean overcooking or using too much flour. Microwaves heat fast and unevenly, so always start with 1 minute, then add 10–15 seconds as needed. In this coffee cake mug cake recipe , melted butter and milk keep the crumb tender, while a precise flour amount prevents toughness.
