Keto Cinnamon Roll Mug Cake
Yields2 Servings
Prep Time5 minsCook Time2 minsTotal Time7 mins
 2 tbsp (0.5oz/16g) finely ground almond flour
 2 tbsp (0.5oz/16g) finely ground coconut flour
 2 tbsp (1oz/28g) pure brown erythritol or 1.5 tbsp (20g) Golden Monk Fruit Sweetener or this 1:1 brown erythritol blend)
 1 egg
 1 tbsp (15ml) unsweetened almond milk
 1 tbsp melted butter or coconut oil
 ½ tsp (gluten-free) baking powder
Cream Cheese Topping:
 2 tbsp cream cheese
 1 tbsp heavy cream
 (optional) (ceylon) cinnamon
1

Add all of the ingredients for the mug cake base into a middle-sized bowl.
Whisk until you get a smooth and chunk-free dough.

2

Grease your microwave-safe mug or bowl with cooking oil that doesn't have a strong taste (I like to use coconut oil, butter or avocado oil).

3

Add your cake batter into a mug or bowl (the mug should be at least double the size of the mixed ingredients).

Instructions: Microwave
4

Microwave for about 1-3 minutes.
(The cooking time in your microwave may vary heavily depending on what microwave and what settings you're using.
A broad rule of thumb: Approx. 1 Minute at 1200 Watt and more like 2-3 minutes at <600 Watt.

If you don't know the Wattage power of your microwave I'd recommend baking your mug cake for a shorter time period (60 seconds) first and continue baking for a few more seconds if needed.
This will avoid that the mug cake dries out.
You can test if your mug cake is completely cooked by pricking the center with a toothpick - if it comes out "clean" it's ready!

Instructions: Oven
5

Preheat your oven to 350 degrees Fahrenheit (180°C).
Follow the same steps as above.
Bake your mug cake for about 10-15 minutes.

6

(Optional): Melt the cream cheese for the cream cheese topping.
I prefer to do that with a double boiler in a small bowl but you could also simply pop the cream cheese into your microwave for a few seconds until it’s melted.

7

(Optional): Combine the melted cream cheese with the powdered erythritol and the heavy cream.
Make sure no chunks of powdered erythritol are left.

8

(Optional): Pour the liquid cream cheese topping over your baked mug cake and sprinkle a bit of cinnamon on top.

9

Enjoy while it's still warm or cover with plastic wrap and enjoy cold whenever you want.
Both options taste good!

Store for up to 2 days.
