How to Make It – Step by Step
Step 1: Mix the Base
In your mug, combine 2 tablespoons almond flour, 1 tablespoon keto sweetener, 1/2 teaspoon cinnamon, 1/4 teaspoon baking powder, and a pinch of salt. Stir well.
Step 2: Add the Wet Mix
Pour in 1 tablespoon melted butter, 2 tablespoons unsweetened almond milk, and 1/4 teaspoon vanilla extract. Mix until you have a smooth batter.
Step 3: Optional Cream Cheese Swirl
Add 1 tablespoon softened cream cheese and swirl gently with a toothpick or spoon for a cinnamon-roll-style effect.
Step 4: Microwave It
Microwave on high for 90 seconds. The cake should rise and set without overcooking. Let it rest for 30 seconds before serving.
Starter Tip Before Cooking
Let melted butter cool slightly before mixing to prevent clumping. And always stir cinnamon well to distribute flavor evenly.

Variations to Try (Detailed)
Keto Cinnamon Roll Mug Cake
To mimic a real cinnamon roll, use the same base but mix 1/2 tbsp sweetener + 1/4 tsp cinnamon + 1/4 tbsp melted butter and swirl into the batter like cinnamon sugar filling.
Top with a quick cream cheese glaze (cream cheese + powdered sweetener + almond milk) for that iconic finish. Optional: Add a pinch of nutmeg for extra bakery-style aroma.
Keto Cinnamon Bun Mug Cake
Go for a fluffier, more bread-like bun by increasing almond flour to 3 tbsp and baking powder to 1/2 tsp. Add 1 tsp Greek yogurt or sour cream for tenderness.
Top with a sugar-free glaze or a scoop of whipped butter. This version is best enjoyed slightly warm with a fork!
Keto Apple Cinnamon Mug Cake
Stir in 1 tablespoon of chopped zucchini or chayote (apple texture mimic) sautéed in cinnamon and butter until soft.
You can also use apple extract (1/4 tsp) for flavor. This brings the fruity element without the carbs. Sprinkle extra cinnamon on top for warmth.
Storage Tips
- Enjoy immediately for best texture
- If needed, refrigerate for 1 day and reheat in microwave for 15–20 seconds
