Ingredients
For the Cake:
Advertisements
- 2 tablespoons avocado oil (or melted coconut oil)
- 3 tablespoons almond flour (fine-ground for best texture)
- 1 large egg
- ½ teaspoon vanilla extract
- ½ teaspoon ground cinnamon
- ½ teaspoon baking powder
- 1 teaspoon monk fruit sweetener (or stevia, to taste)
For the Cream Cheese Glaze:
- 2 tablespoons whipped cream cheese
- 1 tablespoon water (or heavy cream for extra richness)
- Pinch of cinnamon for garnish
Instructions
- Mix the batter:
In a microwave-safe mug, whisk together oil, almond flour, egg, vanilla, cinnamon, baking powder, and monk fruit until smooth. The mixture should look like slightly thick pancake batter. - Microwave:
Place the mug in the microwave and cook on high for 90 seconds. Cooking time may vary by microwave wattage, so check for doneness — the cake should spring back lightly when touched. - Release and plate:
Run a butter knife gently around the edges, then invert the mug onto a plate. The cake should slide out easily. - Make the glaze:
Using the same mug (no need to clean it), add cream cheese and water. Microwave for 20–25 seconds until soft, then stir until smooth. - Drizzle and enjoy:
Pour the glaze over your warm cinnamon roll cake and sprinkle with a touch of cinnamon. Serve immediately for that gooey, just-baked magic.
Tips for the Perfect Keto Mug Cake
- Choose the right mug: A standard 8–10 oz coffee mug works best. Avoid narrow or tall mugs — they can cause uneven cooking.
- Don’t over-microwave: Every 10 seconds matters! If it feels dry, try reducing cooking time slightly next time.
- Texture control: For a more cake-like crumb, beat your egg first. For a denser “cinnamon roll” feel, mix it directly in the mug.
- Sweetness balance: Monk fruit sweetener mimics sugar closely, but if you use erythritol or stevia, adjust to taste to avoid bitterness.
Substitutions & Variations
- Oil swaps: Coconut oil or melted butter work beautifully — coconut oil gives a subtle tropical hint.
- Flour swap: Replace almond flour with 1 tablespoon coconut flour, but add an extra tablespoon of liquid (it absorbs more).
- Dairy-free: Use dairy-free cream cheese or coconut cream for the glaze.
- Protein boost: Add ½ scoop of unflavored or vanilla whey protein to increase macros and create a firmer texture.
- Toppings: Try sugar-free caramel drizzle, toasted pecans, or a dusting of powdered erythritol for café-level presentation.
Keto Mug Cake FAQs
Can I make this without a microwave?
Yes — pour the batter into a small oven-safe ramekin and bake at 350°F (175°C) for about 10–12 minutes or until firm to touch.

Can I use almond meal instead of almond flour?
You can, but the texture will be slightly coarser and less fluffy. Almond flour yields a softer, more cake-like result.
Can I make it ahead of time?
This cake tastes best fresh, but you can refrigerate leftovers for up to 24 hours. To reheat, microwave for 15 seconds and add a splash of cream or glaze to revive moisture.
