Introduction

This 3-Minute Keto Cinnamon Roll Mug Cake is a quick and easy treat that satisfies your sweet tooth while keeping carbs low. Perfect for a fast breakfast or a guilt-free dessert, it combines warm cinnamon flavor with a creamy frosting, all made right in your mug.

The image shows a white ceramic mug filled with a baked mug cake that has a golden-brown top layer with a slightly crumbly texture. On top, there is a thick swirl of creamy white whipped topping sprinkled with small brown spice powder and topped with scattered pecan nut pieces in dark brown and reddish tones. The mug is placed on a white marbled surface, with an old silver spoon lying beside it. The colors are warm and inviting, focusing on the contrast between the golden cake, white cream, and rich brown nuts. Photo taken with an iphone --ar 4:5 --v 7

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, mix together the melted butter, almond flour, egg, cinnamon, baking powder, and stevia powder blend until the batter is smooth.

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 cinnamon and stevia blend. Pour the warm glaze evenly over the cooked cake.
Step 4: Soften the cream cheese and mix it with the stevia powder blend until smooth. Swirl this frosting on top of the glazed cake for a classic cinnamon roll finish.

Tips & Variations

Use a low-carb sweetener of your choice if you prefer a different taste or have dietary restrictions.
Add a pinch of nutmeg or vanilla extract to the batter for extra depth of flavor.
For a dairy-free version, substitute butter with coconut oil and cream cheese with a vegan alternative.

Storage

Enjoy your mug cake fresh for the best texture and flavor. If needed, you can store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat briefly in the microwave to soften before eating, but the frosting may lose some of its creamy texture.

How to Serve

The image shows two white mugs, each filled with a cinnamon roll mug cake topped with a thick layer of creamy white frosting swirled on top. The first mug’s cake is golden brown with visible pieces of pecans embedded in the moist, slightly crumbly texture, and the frosting is sprinkled with cinnamon and decorated with whole pecans. The second mug also contains a golden-brown cinnamon roll cake with gooey cinnamon swirl patterns and is overflowing slightly with white icing dripping down the side. The frosting on top is sprinkled with cinnamon and drizzled with caramel sauce, all set against a white marbled surface with a spoon nearby. photo taken with an iphone --ar 4:5 --v 7
