Keto Chocolate Mug Cake Ingredients

Keto Chocolate Mug Cake ingredients
  • 3 tablespoon almond flour
  • 1 tablespoon unsweetened cocoa powder
  • 1 tablespoon low-carb brown sugar alternative
  • 1 tablespoon sugar-free chocolate chips
  • 1 egg, at room temperature
  • 1 tablespoon melted butter
  • ½ teaspoon baking powder
  • Pinch of salt

How to Make Keto Chocolate Mug Cake

You'll need a small bowl to mix everything together in, for starters. Combine the almond flour, cocoa powder, brow sugar substitute, about half a tablespoon of sugar-free chocolate chips, an egg, melted butter, baking powder, and a pinch of salt. Hey, that's everything! Stir it all together until it's moist. Pour into a mug that you've already greased with butter or nonstick cooking spray.

How to Store and Serve Keto Chocolate Mug Cake

We don't pretend that you're going to have leftovers from this cake. But, it's possible you won't eat it all at once. You might want to save some for later. In that case, just wrap the top of the mug in plastic wrap or aluminum foil and keep it at room temperature. It should be good for a couple of days, no problem.

That being said, you might enjoy adding more chocolate chips on top if you want to reheat it briefly, later. Or it might be fun to serve this with a dollop of whipped cream, some keto vanilla ice cream, or a handful of chopped strawberries or fresh raspberries.

Substitutions and Alterations

Keto baking is a delicate dance, to be sure. It doesn't take well to making a lot of substitutions. That being said, you can easily use a keto granulated sugar instead of brown sugar, with no ill effect. You can add a little bit of vanilla extract; about ¼ teaspoon would work to intensify some of the chocolate flavors. A tablespoon of peanut butter wouldn't hurt the situation here, either, swirled into the batter before baking it in the microwave. A couple of tablespoons of chopped walnuts or pecans can be accommodated by this batter, too. Just don't overhaul the basic recipe. Anything you would add to a chocolate cake can be added here, in small measures. Sprinkle the top with shredded coconut when it comes out of the microwave, or top it with toasted nuts.
