This Lemon Blueberry Mug Cake is the perfect way to welcome Spring! It’s light and fluffy, and exploding with flavor. Warm blueberries encased in a lemony sponge burst with sweetness in each bite!
Garnished with whipped cream or a dusting of Swerve Confectioner’s sugar, this Lemon Blueberry Mug Cake is even fancy enough to serve to company. It’s a treat that works well for special diets, too, as it’s a THM S that’s gluten-free, keto, and can easily be made dairy free by replacing the teaspoon of butter with coconut oil.
Initially, I tried making this Lemon Blueberry Mug Cake with a greater amount of coconut flour to cut down on the caloric density of the almond flour, but the texture felt gritty in the mouth. I reworked the ratio of wet to dry ingredients, and was able to use just two tablespoons of almond flour and half a tablespoon of coconut flour for a fluffy cake texture that doesn’t feel heavy or greasy.
If you’re an even crazier lemon fanatic than I am, you can add lemon zest to this recipe, and even a quarter teaspoon of Baobab powder to enhance the citrus-y taste (and Vitamin C!).
I used frozen blueberries in this recipe, but fresh work too. Use raspberries, black raspberries, cranberries, chopped up strawberries, or a combination of them for different twist!
Since healthy fats are the star of this Lemon Blueberry Mug Cake, you can garnish it with a squirt of whipped cream and not worry about crossing fuels.
