Keto Vanilla Mug Cake

Keto vanilla mug cake is low-carb, low-sugar, and ready in less than two minutes in the microwave. Dessert for one is served!

We've been posting a few of these delicious keto mug cakes here at MPOF, because even if you're following a keto diet, it doesn't mean you have to give up something sweet now and then. And sometimes a single-serve cake is just what you need.

This keto vanilla mug cake is the most basic but perhaps the most versatile because of it. Sometimes you just want vanilla, and that's ok. We know chocolate gets all the cravings most of the time, but vanilla is stealthy and not to be underrated. Just think of all the things you can pair with this little cake . . .

Keto Vanilla Mug Cake Ingredients

• ¼ cup blanched almond flour
• 1 tablespoon erythritol sweetener
• 1 egg, at room temperature
• 1 tablespoon melted butter
• ½ vanilla extract
• ½ teaspoon baking powder
• Pinch of salt

How to Make Keto Vanilla Mug Cake

So it's easy! Combine the almond flour, erythritol sweetener, egg, melted butter, vanilla extract, baking powder, and salt in a small bowl. Mix it together until it's moist and forms a batter. Transfer to a mug that you've sprayed with nonstick spray and microwave for 90 seconds. That's it. Mystery solved. Less than two minutes to cake bliss.

How to Store and Serve Keto Vanilla Mug Cake

So yes, this is a single-serve item. It's simple to make and you might eat it all in one clip. Or you might not. And in that case, you can always cover the top with some plastic wrap or aluminum foil. The cake will keep for a couple of days at room temperature, no problem. You can serve this keto mug cake just as it is, or scatter a handful of blueberries over the top. If you like a bit of extra sweetness, sprinkle some keto-friendly confectioners sugar over the top. Your call!

Substitutions and Alterations

As you might know, keto baking is a particular kind of thing. It doesn't take too easily to substitutions when it comes to its flour and its fats; those are what need to give it structure because you're dealing with gluten-free baking, basically. We don't really recommend switching the flour or using an egg substitute without the caveat that the texture of this keto mug cake will likely suffer.

But feel free to switch out the vanilla extract for other kinds (almond, lemon, etc.), to change the flavor profile a bit. Vanilla is a good base to experiment with.

Add some spices, such as cinnamon, ginger, nutmeg, and so forth. We also like adding lemon zest to the batter; you only need a little bit. Lime or orange zest would be delicious, too. In those cases, if you're going citrus, you can add a squeeze of fresh juice, too. It won't hurt!

You can also fold in some chocolate chips if you can't decide between a chocolate or vanilla mug cake, or drizzle a keto chocolate sauce on top. Chopped up pistachios, walnuts, or almonds add some crunchy contrast when sprinkled over the top of this cake. Just some ideas!
