Keto birthday cake mug cake is a dreamy, easy, single-serve treat when you want to feel festive, regardless of whether or not it's your birthday. Or anyone else's!
Sometimes you want just a little bit of cake and don't want to expend a whole lot of effort. If you're following a keto diet, though, you have to make different choices, but that doesn't mean you have to sacrifice something sweet.
These keto birthday cakes can be made right in a mug in the microwave. It doesn't get any easier than that. The best part is that it's gluten-free, low-carb, and low-sugar. It's a great way to satisfy a craving for something sweet when you want an old-fashioned vanilla cake taste, with some sprinkles thrown in for good measure.

- Pinch of salt
- 1 teaspoon sugar-free sprinkles
For Frosting

How to Make Keto Birthday Cake Mug Cake
This is super easy, and super fast. In fact, it might even be a little too easy and fast. But the good news is that it's keto, so the sugar is low. All you need to do is combine the almond flour, sweetener, egg, melted butter, vanilla extract, baking powder, salt, and sprinkles in a small bowl. Microwave it for less than two minutes and you're good to go. We love a dollop of frosting on the top; it's made with some cream cheese, powdered erythritol, a splash of almond milk, and a small bit of vanilla extract. And, of course, don't forget those sprinkles (look for sugar-free ones!).
How to Store and Serve Keto Birthday Cake Mug Cake
Once this cake is made, it's so good warm right out of the microwave. But if you need to store it, cover the top of it with foil or plastic wrap very tightly and keep it at room temperature. It should be good for a couple of days, if for some crazy reason you don't devour this in one clip!
Substitutions and Alterations
Generally speaking, it's not advisable to mess too much with a keto recipe because they're pretty carefully calibrated. Almond flour functions differently than regular all-purpose flour, and is different still from other types of gluten-free flours (looking at you coconut flour!).
However, there are a few switches you can make that won't change the texture or taste of the cake. You can use any other kind of plant-based milk (or even regular cow's milk). Or, you can up the amount of vanilla extract if you like, or use an almond extract or lemon one if you're interested in changing the flavors a bit. Want to save on calories or you're pressed for time? Skip the frosting altogether if desired.
