Coffee Mug Cake

This coffee mug cake makes the perfect single serving treat that takes less than a minute to make. It’s fluffy, moist, and topped with an easy streusel. 

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 mug cake 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.
