Ultimate Keto Blueberry Sponge Cake In A Mug
Instead of making pancakes or waffles, make this easy Keto breakfast recipe that takes way less time to make. This blueberry sponge cake in a mug is soft and fluffy like a pancake but sweet like a cake. Don’t worry, you won’t be adding many carbs to your breakfast, as all sweetening products are replaced with Keto-friendly ingredients. You can assemble the recipe in under 5 minutes, so this is also a great Keto breakfast recipe for anyone who always ends up in a rush in the mornings. Even if you’re in a rush, you can still enjoy this sweet and delicious sponge cake breakfast! If you want to serve your sponge cake with a little whipped cream, you can whip heavy cream and liquid stevia together in a stand mixer or food processor.
Other ingredients to add
Like to have a little more in your sponge cake? Try stirring in crushed nuts for more texture. Keto-friendly nuts include cashews, walnuts, pecan, hazelnuts, and even peanuts. Blueberries also happen to taste very good with lemon. Try mixing a little lemon zest in your dry ingredients!
Can other berries be used?
Blueberries are one of the most Keto-friendly berries out there. If you don’t like blueberries, try raspberries or strawberries. If you’re using strawberries in the mug cake, make sure to chop them finely.
What type of mug should I use?
A heat-safe mug or dish can easily be a coffee cup from your kitchen. Choose any type of ceramic mug to keep your hands safe as well as cook the sponge cake. If you own a ceramic ramekin, you can also cook your sponge cake in there.

Definitely easy and worth making for a treat. But if recipe makes 2 servings its a lot of carbs!
PropitiousRadish992454 a month ago
4 net carbs per serving is a lot?

Super yummy! I added some lemon zest. I made this once with cream cheese, and just now I subbed the cream cheese for crème fraiche, which is similar. A great snack or dessert.

Is this 2 servings in 1 mug?
Higs a year ago
I am wondering the same thing… I logged the individual ingredients and it read 8 net carbs and 385 calories. Based on that, this does appear to be two servings.

This is better than any keto "cake" or "muffin" I have ever had! Really hit the spot!

Let’s face it, we all crave bready comfort food on this diet. I was looking for a quick fix, but this recipe surpassed my expectations. The cake has a nice light crumb and it’s quite fluffy. I substituted blackberries for blueberries, added a small amount of lemon zest and made a cream cheese icing for the topping. Sprinkle with a little cinnamon and enjoy. This recipe is a winner, I’ll come back to this recipe again and again.

This is the best! To make it really decadent, I slathered on some cream cheese/stevia icing on top!
MirthfulMacadamia118611 a year ago
Absolutely beautiful. I love how easy it is to make! Will be having this over and over. I used ricotta and instead of stevia I used Rapadura syrup! 😃😃😃
StellarKetone637400 a year ago
Is it possible to make this in the oven? I don't have a microwave, and I'm a novice at baking. Thanks
RemarkableArugula311543 a year ago
If you really want it to puff up, try a super hot oven! Like 400- 450 for a short amount of time (5-10min) so good.
OutstandingArugula496981 a year ago
Hi I don’t have a microwave either I made it using almond flour and used two of the small soufflé type ceramic holders the ingredients filled both and I baked them at 160 fan for 20 mins and they have come out perfectly

Excellent recipe. Love it. I swapped blueberries for cranberries and it was delicious.
LizPepper a year ago
Delish! I made one mug with fresh blueberries and another with a fresh strawberry and it's perfect! I heated them together and for 3 minutes (90 seconds each). Came out just right. Not dry. Oh and I only added had the sweetener to each as 1 tbsp would be too much.

OMG these are amazing!! I made a double batch and instead of using vanilla I used lemon extract. Out of this World. This will be one of my staple go-to recipes for when I have the bread type / sweet type cravings... Highly recommend you try this one.
