Ingredients You’ll Need

To make this Keto Blueberry Mug Cake, you only need a few simple ingredients, most of which you likely already have in your pantry if you’re following a keto diet. Here’s what you’ll need:

2 tablespoons almond flour
1 tablespoon coconut flour
1/4 teaspoon baking powder
1 tablespoon unsweetened almond milk (or any other low-carb milk)
1 tablespoon melted butter
1 large egg
2 tablespoons blueberries (fresh or frozen)
1 tablespoon keto sweetener (like erythritol, monk fruit, or stevia)
1/2 teaspoon vanilla extract
Pinch of salt

Feel free to adjust the sweetness level to your liking, and you can always toss in some extra blueberries if you love that burst of fruity flavor!

Step-by-Step Instructions

This Keto Blueberry Mug Cake is as easy as 1-2-3! Follow these simple steps, and you’ll have a delicious dessert in minutes.

Step 1: Prepare Your Mug

Start by choosing a microwave-safe mug. This is a one-serving recipe, so pick a mug that has a little extra space for the batter to rise as it cooks. I recommend a 12-ounce mug to give it enough room.

Step 2: Mix the Dry Ingredients

Add the almond flour, coconut flour, baking powder, and a pinch of salt into the mug. Stir them together using a fork until all the dry ingredients are well combined.

Step 3: Add the Wet Ingredients

Next, pour in the melted butter, egg, almond milk, sweetener, and vanilla extract. Until the batter is smooth, whisk everything together. Make sure there are no lumps, as you want the cake to be light and fluffy.

Step 4: Fold in the Blueberries

Gently fold the blueberries into the batter. Be careful not to crush them too much, as you want those little bursts of berry goodness in every bite. If you’re using frozen blueberries, you can add them directly to the batter without thawing them first.

Step 5: Microwave the Cake

Place your mug in the microwave and cook for about 1 minute and 30 seconds to 2 minutes, depending on the strength of your microwave. Keep an eye on it while it’s cooking, as mug cakes tend to rise and can overflow if cooked too long. The cake should rise, set in the middle, and look firm on top when done.

Step 6: Enjoy!

Let your mug cake cool for just a minute or two, then dig in! It’s delicious on its own, but if you want to get fancy, top it with a little bit of whipped cream or sugar-free syrup. Trust me, you’ll feel like you’re indulging in something special.

Additional Tips

Don’t Overcook: Microwave cooking times vary, so keep a close eye on your cake. It’s better to stop cooking early and let it sit for a moment rather than overcooking it.
Use Fresh or Frozen Blueberries: Both work perfectly in this recipe. If using frozen, don’t thaw them beforehand – just fold them into the batter as they are.
Add Some Spices: If you like extra flavor, feel free to sprinkle in a pinch of cinnamon or nutmeg. It’ll give your mug cake a cozy, spiced vibe.
Top with Whipped Cream: For an extra indulgence, top your mug cake with some homemade whipped cream or a dollop of sugar-free Greek yogurt.

Keto Notes

This cake is 100% keto-approved. Almond flour and coconut flour are both excellent choices for low-carb baking, as they’re high in fiber and healthy fats.

Erythritol, monk fruit, and stevia are all great options for keeping things low-carb and sugar-free.
