Ingredients You’ll Need

Keeping this 3-Minute Keto Cinnamon Roll Mug Cake Recipe simple means each ingredient plays an essential role in achieving that perfect blend of taste and texture. These pantry staples come together to create a moist, flavorful cake with a classic cinnamon swirl, topped with a creamy finish.

2 tbsp butter, melted: Adds richness and moisture while helping to bind the ingredients together perfectly.
3 tbsp almond flour: The gluten-free base that keeps this mug cake light but satisfyingly dense for keto.
1 egg: Essential for structure and fluffiness in the cake.
½ tsp ground cinnamon: Provides that signature warming spice that defines this dessert.
½ tsp baking powder: Gives the cake a gentle lift so it’s tender rather than dense.
1 tsp stevia powder blend (like Truvia): Sweetens without the carbs, perfectly balancing the flavors.
1 tbsp butter (for glaze): Creates a silky cinnamon glaze that enhances the topping.
¼ tsp ground cinnamon (for glaze): Intensifies the aromatic cinnamon flavor in the glaze.
½ tsp stevia powder blend (for glaze): Adds sweetness to the glaze to complement the cake.
1 oz cream cheese: The star of the frosting, lending a creamy tang that elevates the entire dish.
½ tsp stevia powder blend (for frosting): Sweetens the cream cheese frosting perfectly without any sugar.

How to Make 3-Minute Keto Cinnamon Roll Mug Cake Recipe

Step 1: Mix the Mug Cake Batter

Start by combining the melted butter, almond flour, egg, ground cinnamon, baking powder, and stevia powder in a microwave-safe mug. Stir everything thoroughly until the batter is smooth and even, making sure there are no lumps so the cake will cook evenly.

Step 2: Microwave to Perfection

Pop your mug into the microwave and cook on high for 90 seconds to 2 minutes. Keep an eye on it—the cake is ready when the top looks set and no longer wet. The kitchen will fill with that irresistible aroma of cinnamon and toasted almond flour.

Step 3: Prepare and Pour the Glaze

While the cake bakes, melt a tablespoon of butter in a small bowl, then stir in the cinnamon and stevia for the glaze. Once the mug cake is warm out of the microwave, drizzle this luscious glaze over the top to soak in just enough to add a shiny sweetness and extra cinnamon kick.

Step 4: Top with Cream Cheese Frosting

Soften the cream cheese and mix it with stevia powder until smooth. Dollop or swirl the frosting on top of the warm mug cake. This creamy layer echoes the classic cinnamon roll experience and makes every bite utterly indulgent.

How to Serve 3-Minute Keto Cinnamon Roll Mug Cake Recipe

Garnishes

Feel free to sprinkle a pinch of extra cinnamon or chopped pecans on the frosting for an added crunch and visual appeal. A light dusting of powdered erythritol can also mimic a traditional powdered sugar finish for that bakery feel.

Side Dishes

For a complete breakfast or dessert experience, pair your mug cake with a hot cup of unsweetened coffee or chai tea. A dollop of whipped cream or a few fresh berries on the side brings a refreshing contrast to the warm, spiced cake.

Creative Ways to Present

Serve this delightful mug cake in clear glass mugs to show off the layers of cake, glaze, and frosting. Alternatively, spoon the batter into a ramekin for a more elegant look. If you’re sharing, consider serving a few mini versions in espresso cups for a fun cinnamon roll tasting party.

Make Ahead and Storage

Storing Leftovers

If you happen to have any leftovers—which is rare because it’s so good—you can store the cake in an airtight container in the refrigerator for up to 2 days. Keep the frosting separate to prevent it from becoming watery.

Freezing

This mug cake is best enjoyed fresh, but you can freeze the unfrosted cake portion wrapped tightly in plastic wrap and then foil for up to one month. Thaw completely before reheating and applying fresh glaze and frosting.

Reheating

To warm up your mug cake, microwave for about 20-30 seconds until heated through. Add fresh glaze and cream cheese frosting after reheating to maintain that just-made flavor and texture.

FAQs

Can I use a different sweetener instead of stevia?

Absolutely! You can swap stevia for other keto-friendly sweeteners like erythritol or monk fruit sweetener depending on your taste preference and what you have on hand.

Is almond flour the only flour option for this recipe?

Almond flour works best for texture and flavor in this recipe, but if you’re allergic or want to try something else, finely ground coconut flour can be used with adjustment to liquid ratios. However, coconut flour tends to be more absorbent.

Can I make this recipe in a conventional oven?

Yes, bake your batter in a small ramekin at 350°F (175°C) for about 12-15 minutes until a toothpick comes out clean. Microwaving remains the quickest and easiest method.

How do I get a swirl effect like a real cinnamon roll?

While this mug cake captures the flavor of cinnamon rolls, the swirl effect is mimicked by the glaze and frosting on top, which is simpler for this quick single-serve recipe.

Can I double or triple the recipe?

You can, but it’s best to make each mug cake separately to ensure even cooking and that delicious mug cake texture. Microwaves vary and multiple mug cakes may cook unevenly.
