Coffee cake is best when it is warm and fresh from the oven, and now it's possible to get that fresh-baked experience every morning. All you have to do is make a single-serving coffee cake quickly and easily in a mug. You already have a mug ready to go for your morning coffee, why not grab a second mug to make a coffee cake?

This recipe for cinnamon streusel coffee mug cake is so easy because it uses a prepared cake mix. All you have to do is scoop out some cake mix from the box and mix it with water. The cake mix does the work for you and it cooks up perfectly in the microwave. This recipe calls for yellow cake mix to achieve that classic crumble-topped coffee cake look, but you can feel free to use any cake mix you have on hand—just be sure to store the remaining cake mix in a resealable plastic bag for future use. Once you get a taste of fresh coffee cake in the morning, you will be hooked!

The best part about this coffee cake in a mug is that the prep time is a snap. Plus, the recipe only uses the microwave, it is also safe for older children to prepare and feel successful in the kitchen. Just be sure to use care when taking the mug out of the microwave in-between steps and when ready to top and serve. Since microwave strengths vary and some mugs become very hot, use oven mitts or a thick kitchen towel to protect your hands.

Recipe Variations

  • The streusel topping calls for chopped pecans for flavor and texture. Leave them out if you prefer a nut-free version or substitute other nuts to suit your taste.
  • Swap the yellow cake mix for white cake mix, or for extra flavor a spice cake mix is quite delicious.
