Need a personal sized low carb cake for someone special that takes minutes to make? Try this gluten free keto birthday cake. It bakes in only 2 minutes.
Today is the income tax due date in the US, but it’s also a special day for me. I’m another year older and celebrating with a low carb and gluten free birthday mug cake that took two minutes to bake in the microwave.
I admit that this cake baking thing in the microwave didn’t really appeal to me at first, but after seeing a lovely Valentine’s Day mug cake at SugarFreeMom.com, I was sold on the idea. So, I want to thank my fellow low carb blogger Brenda for turning me around.
I didn’t want to spend a lot of time baking a cake for my birthday and I especially didn’t want to have leftovers that I’d be eating after.
I’m the only one in the family who follows a low carb diet so this personal sized keto birthday cake was perfect for me. It makes 4 cute sized slices!
I had planned to dress up the cake a little more with decorative frosting, but the batch of frosting I made was just enough to frost the cake without any left to decorate.
Had I planned things better, I would have made a double batch of frosting so I could do the traditional birthday cake frills. Oh well. Maybe next year.
Mug cakes are typically baked in a cup and left in there. Since I wanted this to be a miniature double layer frosted birthday cake, I used a 2-cup round Pyrex storage container for each cake layer.
A regular ramekin is another great dish for baking these keto birthday cake layers. If you have a wide mug, that would probably work as well. You just want to make sure whatever you use is microwaveable.
I’m not a fan of plastics or using them in the microwave so I don’t recommend baking these cake layers in plastic dishes. My Pyrex container was pretty hot taking it out of the microwave so use caution in removing the hot cakes. I used pot holders.
This is a yellow gluten free cake that bakes up nicely in the microwave. I suppose the cakes could also be cooked in an oven if you don’t mind waiting a little longer for them to be done.
Frosting the simple keto mug cake
The frosting I used was the recipe from my gluten free coconut cupcakes. The amounts given in that recipe were just enough to frost this two layer mug cake.
If you prefer chocolate frosting, there’s a great recipe listed on my chocolate frosted zucchini brownies. This is the perfect cake to bake up when you are craving something sweet but don’t want a lot of servings.
Low Carb Keto Birthday Cake in Minutes Recipe
This mini birthday cake can be a fun activity to do with the kids. The size kind of reminds me of the cakes from the Easy Bake Oven that I used to make with my older daughter. Of course, this is a much healthier cake than the mixes we used back then.
