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.

If necessary, you can mix the ingredients in a separate mixing bowl before adding it to your heat-safe dish or mug.Step 3

I love this for a after dinner snack. I held back a small amount of cream cheese to make drizzle for the top after it was cooked. In addition, I added some toasted pecans on top for some crunch and to balance my macros. Delicious!

Made this again and it's still just as wonderful. Used dehydrated blueberries and whipped cream cheese. Had to cook a minute and a half in the microwave to get the middle done. Otherwise this is 👍👍👍

I'm insulin resistant so made some changes to help me. I LOVE all things coconut, so instead of vanilla I used 1/2 tsp coconut extract, and instead of Blueberries used 1 Tbsp of unsweetened coconut flakes. I also only use allulouse sweetener (1 1/2 Tbsp) since I learned according to my CGM that LOWERS MY BLOOD sugar! (Ben Bikman teaches about this). Turned out GREAT!! Love the taste and textures. This is something we will REPEAT!!! Will modify next for a coconut cocoa powder experiment, looking forward to that as well!

This was very good! Would make it again. Note: there is a 1/4 tsp of baking powder in the ingredients, but the instructions do not say where to add it. I added it just before the blueberries.
Shewoff642 2 months ago
I did that also and it worked out well. Thanks for the tip.

Quick easy and tasty. I’ve cooked this recipe with almond flour and coconut flour. Much prefer almond flour as it gives a better flavour. If using almond flour use 8 tbsps. If your microwave isn’t so powerful then cook for a minute and half.

Wow what an amazing pudding. Great for if I want a desert.

Pudding? Did you not bake it? Mine definitely wasn’t a pudding or liquid type product. 🤷♂️

Any instructions for air fryer or oven? I don’t have a microwave

Maybe cooked in a gentle bubbling water bath, like some home-made puddings? Or cooked in a non-stick pan. Maybe reduce liquids a bit for that.

MirthfulRadish216606 3 months ago

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.
