Keto Birthday Cake
It's summer and NOT my birthday - so what better time to experiment with a keto birthday cake?
I just bought some Keto Birthday Cake Protein Powder and wanted to try out a recipe with it because it smelled like the most delicious thing on the planet. I tried it in a protein shake and it did not disappoint.
And I am a creature of habit and have had the SAME Almond Butter Collagen Shake for breakfast for over a year now! So switching it up for a day or two was a big deal for me.
Now, the main flavor in here is the Keto Birthday Cake Protein Powder, but you can use your regular whey protein (best if flavored) and if you just don't want to use ANY protein, then follow my other Keto Single Serve Birthday Cake which is just as easy and just as yummy!

How to make keto sprinkles
First all, you can use whatever variation of keto sprinkles that you want. I just happen to be partial to these ones!
Check out my Keto sprinkles post to make your own keto sprinkles. Hint - it is SUPER EASY! Another hint - it just takes a smidge of water, food coloring and unsweetened shredded coconut!
Once you make the sprinkles, you can use as little or as much as you'd like! I used 1 teaspoon each of red, green, blue and yellow. I generally make a big batch and then keep them on hand for when I need sprinkles.
I also sprinkled a few sprinkles in the cup before putting my batter in to give a few more sprinkles on top.
How to make a mug cake?
So technically this is a mug cake that I did not make in a mug. I mean, you CAN make it in a mug.
You just need to consider if you want ao skinny, tall cake or if you want a wider, flatter cake. This is a hefty mug cake recipe, so this will categorically NOT fit into a small or normal sized mug. You'll need a large mug or large ramekin mug. I actually used a smaller bowl.
Mug cakes traditionally have some nut flour, egg, baking powder, and some flavors. Then you grease a mug, put the batter in, and microwave it for 60-120 minutes. Then take it out and flip it! Simple, right?
This is what it looked like after taking it out of the oven and flipping it over:
You can eat it as is or frost it. I actually do both. Today, I felt like frosting it and sprinkling some color on there!
Can you eat cake on the keto diet?
Um, YES! Especially if it is MY cake. I vary my ingredients a lot, but I always use nut flours and usually protein powders to give the consistency and flavor that I want.
This keto birthday cake is so (dare I say....) MOIST! My regular keto single serve cake is a bit dryer, but not too dry. The difference is that one uses coconut flour and this one uses whey protein. Coconut flour is GREAT for soaking up liquid, so it makes sense!

Other Single Serve Desserts You May Like
- 4 teaspoons colored keto sprinkles
- 1/4 cup almond flour
- 1 scoop whey protein (I use birthday cake flavor)
- 2 tablespoons Lakanto monkfruit
- 1/2 teaspoon baking powder
- 1 egg
- 2 tablespoons heavy whipping cream
- 1 teaspoon vanilla extract
- 1/8 teaspoon almond extract
- 1 tablespoon butter
- 2 ounces cream cheese, room temperature
- 1 tablespoon butter, room temperature
- 2 tablespoons powdered monkfruit
- 1 tablespoon heavy whipping cream
- 1/8 teaspoon vanilla extract
- Prepare sprinkles according to instructions! They are super simple, but they do take a few hours to dry out, so you can make them the night before if you want!
- Combine all ingredients into small bowl and beat until creamy.
- There will be enough for 2 cakes, but sometimes things don't turn out when the proportions of ingredients get too small. So you may have leftovers!
- Set aside.
- In a small bowl, combine sprinkles, almond flour, protein, monkfruit, and baking powder. Combine well. NOTE - I added 1 teaspoon each of 4 different colors.
- To the bowl, add a beaten egg, heavy whipping cream, vanilla extract and almond extract. Beat with a fork and combine well.
- In your mug or ramekin, melt butter and swirl around the bottom and sides to give it a good coating.
- Pour batter into prepared mug and microwave for 2 minutes.
- Flip upside down onto a plate and lift off the mug.
- Immediately add frosting so it melts. Add a big glob in the middle and just stir around the top so it melts and starts falling down the sides.
- Add additional sprinkles if desired.
