Versatility — go ahead and add some protein powder to this if you have trouble meeting your protein requirements like I do. I like to use Naked Nutrition’s Naked Collagen.

WHAT YOU’LL NEED

Coconut flour (a wonderful low carb baking ingredient!)
Cocoa powder (I love this raw cacao powder)
Sweetener of choice (I love using Allulose. A monk fruit/erythritol blend also works.)
Eggs
Coconut Oil
Almond milk (unsweetened – or use coconut milk).
Optional: Vanilla Extract or Almond Extract (about 1/4 teaspoon)

The ingredients needed to make keto chocolate mug cakes.

Kitchen Tools:

Two Microwave or Oven Safe Mugs (I like to use a small mug for this recipe – it’s deep chocolate flavor means a small amount is very satisfying!)

How to Make a Mug Cake

Step 1: Use coconut oil to grease 2 microwave-safe mugs and set aside. *If baking your mug cakes, be sure to use oven-safe mugs or baking ramekins.

Step 2: Into a medium mixing bowl, add eggs, melted coconut oil, almond milk, and optional vanilla extract into a bowl and whisk to combine. I make this recipe in a separate bowl and then add to the mugs, which makes the mug cakes bake more cleanly. Feel free to make this directly in your mug.

Step 3: Add in the coconut flour, sweetener, cacao powder, sea salt and baking soda. Stir in well, making sure to stir out the clumps of coconut flour until smooth.

Step 4: Microwave the mug cakes for 1 minute – 1 minute and 45 seconds. Coconut flour tastes the best when it’s slightly undercooked, so it doesn’t dry out. The outside of the mug cakes should be cooked, and the center should be slightly underbaked.

If you do not want to microwave your mug cake, bake the mug cakes in oven-safe mugs or baking ramekins at 350º F for 12-14 minutes.

How to Prep Keto Mug Cakes

This recipe is for 2 mug cakes. Because of the simple ingredients in this recipe, it is best enjoyed hot or warm.

If you’d like to bake one mug cake and save the other to bake later, wrap the top of the 2nd mug with plastic wrap or foil and save for 1-2 days. This way your sweet treat is ready to go!

You can also keep the dry ingredients mixed together in small containers or plastic bags, and add egg, coconut oil, and almond milk when ready to make your microwave cakes.

Keto Chocolate Mug Cake Variations

This easy keto dessert recipe results in a moist cake that keeps blood sugar levels stable. If you love it, you might want to experiment to make your own favorite mug cake recipes.

Can I use Almond Flour? This recipe was developed with coconut flour. Coconut and almond flour (or almond meal) have very different properties, so it isn’t a 1-1 swap. If you want to try using almond flour, it will take about twice as much (1/4 cup almond flour).

Add More Flavor: Try adding almond extract or peppermint extract to make a different flavored cake.

Add Nuts: Add pecans, walnuts, or chopped almonds to the batter to give the cake some texture.

Peanut Butter Versions: For the easiest option, add a drizzle of natural peanut butter to the top of your mug cake. You can also add 2 T of powdered peanut butter (like PB2) and reduce the coconut flour to 1 T.

Make Egg Free: Replace a whole egg with 1 tablespoon of chia seeds soaked in 3 tablespoons of water. For the recipe, use 2 tablespoons of chia seeds and 6 tablespoons of water. This makes a thicker-textured dessert that’s more like a brownie than a cake.

Keto Chocolate Chip Mug Cake: Add the cake batter into the mugs as directed, then add 1 tablespoon of chocolate chips to the tops of the cakes. They will sink in as the cakes bake. Do not stir them in to the batter or they will all end up in the bottom of your mugs! Adding dark chocolate chips adds to the rich chocolate flavor of

Toppings for Mug Cakes

Strawberries and raspberries are great low carb toppings for this delicious cake!
A sprinkle of shredded coconut (unsweetened).
Chopped walnuts or pecans, or even some chopped macadamia nuts.
A quick Keto “frosting” made by mixing 1 tablespoon almond butter, 1 tablespoon coconut oil, 1/2 tablespoon cocoa powder and 1/2 tablespoon powdered erythritol.
Whipped Cream! Add heavy cream to a mixer and whip until stiff peaks form. Add a little sweetener to taste if desired.
90% dark chocolate or sugar-free chocolate chips (these will melt if sprinkled on right away!).
