Ingredients

2 tbsp butter, melted
3 tbsp almond flour
1 egg
½ tsp ground cinnamon
½ tsp baking powder
1 tsp stevia powder blend (like Truvia)
1 tbsp butter (for glaze)
¼ tsp ground cinnamon (for glaze)
½ tsp stevia powder blend (for glaze)
1 oz cream cheese
½ tsp stevia powder blend (for frosting)

Instructions

Step 1: In a microwave-safe mug, combine melted butter, almond flour, egg, ground cinnamon, baking powder, and stevia powder. Stir until the batter is smooth and well mixed.
Step 2: Microwave the mug on high for 90 seconds to 2 minutes, or until the top of the cake is set and springy to the touch.
Step 3: For the glaze, melt 1 tablespoon of butter in a small bowl, then stir in the ground cinnamon and stevia powder. Pour the glaze evenly over the warm cake.
Step 4: Soften the cream cheese by microwaving it for about 15 seconds. Mix in the stevia powder until smooth, then swirl the frosting on top of the glazed cake for that classic cinnamon roll finish.

Tips & Variations

Use a stevia blend that measures like sugar for easier sweetening and better flavor balance.
To add a nutty crunch, sprinkle chopped pecans or walnuts over the frosting before serving.
Adjust microwave cooking time based on your appliance’s strength to avoid overcooking.
For a dairy-free version, substitute butter and cream cheese with coconut oil and dairy-free cream cheese alternatives.

Storage

Enjoy this mug cake fresh for the best texture and flavor. If you have leftovers, cover and refrigerate for up to 2 days. Reheat briefly in the microwave (about 15-20 seconds) before enjoying. Note that the texture may become denser after refrigeration.

FAQs

Can I use a different sweetener instead of stevia?

Yes, you can substitute stevia with erythritol or monk fruit sweetener in equal amounts, but avoid liquid sweeteners as they may affect the batter consistency.

What if I don’t have almond flour?

Almond flour is key to the keto texture, but you can try coconut flour; start with 1 tablespoon and increase gradually as it absorbs more liquid, adjusting other ingredients accordingly.
