I’m all about healthy single-serving desserts, especially if they are quick and easy. Mug cakes are one of my favorites, like a protein mug cake, almond flour mug cake, and keto mug cake.

After sampling the delicious classic coffee cake from Starbucks, I wanted to recreate it and give it a single-serving treatment.

Why you’ll love this coffee mug cake recipe

  • Perfect texture. Fluffy on the inside, tender on the outside, and topped with a delicious streusel topping. It tastes of cinnamon and vanilla and was instantly one of my favorites!
  • Healthier. It’s made with grain-free flours and uses just a little maple syrup to sweeten it.
  • Quick and easy. This one takes seconds to prep and just a minute in the microwave to cook.
  • Single serving dessert. This is the kind of dessert you make when you crave coffee cake but don’t want to put in the effort to make a full recipe! 

Ingredients needed

for the mug cake

  • Almond flour– Blanched almond flour is best, not almond meal. The blanched variety yields a fluffier and lighter cake.
  • Coconut flour– Gives the mug cake the cakey texture, and with no coconut flavor.
  • Baking powder– Gives the mug cake some rise and fluffiness.
  • Maple syrup– Adds sweetness while also keeping the middle of the cake moist and fluffy. Honey or agave nectar work.
  • Cinnamon– A must for the traditional coffee cake flavor!
  • Egg– Room temperature eggs.
  • Milk of choice– Any milk can be used. I used unsweetened almond milk.

For the Streusel topping

  • Almond flour– Again, try to use blanched almond flour.
  • Sweetener of choice– I like brown sugar or coconut sugar. 
  • Almond butter– Gives a buttery crumble topping, minus the butter or oil. Peanut butter or cashew butter also work. 
  • Cinnamon– Adds cinnamon flavor.
  • Milk– To mix everything together to make the crumble.
  • Powdered sugar– Optional, but if you like a glaze. 

How do you make a coffee mug cake?

  1. Prep. Lightly grease a small, microwave-safe bowl or ramekin.
  2. Make the batter. In a small bowl, add your dry ingredients and stir well. Add your wet ingredients, and mix until a smooth batter remains. If the batter is too thick, add extra milk.
  3. Make the streusel. In a small bowl, add your streusel ingredients and mix until combined.
  4. Microwave the mug cake. Transfer the cake batter into a mug and spoon the streusel topping over it and microwave for 1-2 minutes or until cooked. Allow cooling for 1-2 minutes before enjoying!

Tips to make the best coffee cake mug cake

  • Microwaves differ based on make and model. Start with microwaving it at one minute, and if it is not cooked, continue microwaving it in 20-second spurts until it is done.
  • Use a microwave-safe cereal bowl or shallow container instead of a mug. This will ensure the cake is fully cooked through.
  • Do not omit the coconut flour or try to substitute it. It is key to include it to ensure the mug cake is fluffy and tender on the outside.
  • As all coconut flour brands differ, you may need more than half a cup of milk (the suggested amount). Continue adding more milk to the batter until it is smooth and thick.
  • To reduce the fat and calories, you can use an egg white instead of a whole egg.

Frequently asked questions

Why is there no coffee in this recipe?

Coffee cakes, including coffee mug cakes, are designed to be enjoyed with coffee. There is no espresso or coffee in the actual cake batter. 

Can I make this in the oven?

The quickest option is to make the coffee cake in the microwave. However, not everyone has a microwave, so this mug cake can be made in the oven.
Simply replace the microwave-safe bowl with an oven-safe ramekin or similar. Bake at 180C/350F for 10-12 minutes or until a skewer comes out clean.

    Great little Keto coffee cake!! I added 1/2 Tbs. Ground Flax seed for fiber and 2 Tbs. Chopped Walnuts. Might add a little more cinnamon and sweetener next time, just my preference. I’m very happy to find this recipe! Definitely will make for breakfast frequently!
