Ingredients You’ll Need

1/4 cup superfine almond flour
2 tablespoons granulated erythritol or favorite keto sweetener
1/2 teaspoon baking powder
Pinch of salt
1 large egg
1 tablespoon unsweetened almond milk
1 tablespoon unsalted butter melted or refined coconut oil
1/2 teaspoon vanilla extract
1 tablespoon unsalted butter melted for swirl
1 tablespoon powdered erythritol for swirl
1/2 teaspoon ground cinnamon for swirl
2 tablespoons full-fat cream cheese softened
1 tablespoon powdered erythritol for frosting
1/2 teaspoon unsweetened almond milk or heavy cream for frosting
1/4 teaspoon vanilla extract for frosting

Step-by-Step Instructions

Prepare Your Mug
Grab a microwave-safe mug 12-14 oz. Lightly grease if you plan to invert the cake later. A little butter or oil helps the cake release.
Whisk the Dry Ingredients
In the mug combine 1/4 cup superfine almond flour 2 tablespoons granulated erythritol 1/2 teaspoon baking powder and a pinch of salt. Whisk thoroughly until everything looks evenly distributed. This prevents little clumps of almond flour from hiding like tiny dry islands.
Combine the Wet Ingredients
In a separate small bowl melt 1 tablespoon unsalted butter. Add 1 large egg 1 tablespoon unsweetened almond milk and 1/2 teaspoon vanilla extract. Whisk until fully combined and smooth.
Combine Wet and Dry
Pour the wet mixture into the mug with the dry ingredients. Gently stir with a whisk or fork until just combined making sure no dry streaks remain. Do not overmix a few small lumps are fine and keep the cake tender.
Prepare the Keto Cinnamon Swirl
In a very small bowl combine 1 tablespoon melted unsalted butter 1 tablespoon powdered erythritol and 1/2 teaspoon ground cinnamon. Stir until you have a smooth thick spoonable paste. This is your cinnamon roll personality in sauce form.
Layer the Swirl
Dollop about half of the cinnamon swirl mixture over the cake batter in the mug. Gently swirl it into the batter with a toothpick or small knife. Repeat with the remaining swirl mixture creating distinct ribbons of cinnamon.
Microwave to Perfection
Place the mug in the microwave. Cook on high for 60-90 seconds for 1000-1200 watt microwaves. Start with 60 seconds then continue in 10-15 second increments until the cake is cooked through but still moist. Avoid overcooking as almond flour dries out quickly.
Rest Time
Carefully remove the hot mug and let the cake cool in the mug for 2-3 minutes to set further. This tiny pause keeps the structure intact and stops molten cake lava from escaping your spoon.
Soften Your Cream Cheese
Ensure 2 tablespoons full-fat cream cheese is softened to room temperature for a smooth frosting. Microwave for 10-15 seconds on low power if you are impatient like me.
Combine Frosting Ingredients
In a small bowl place the softened cream cheese. Add 1 tablespoon powdered erythritol 1/2 teaspoon unsweetened almond milk or heavy cream and 1/4 teaspoon vanilla extract. This is basically dessert alchemy.
Whisk Until Smooth
Vigorously whisk all frosting ingredients together until completely smooth and creamy with no lumps. A tiny hand whisk or fork works great here.
Frosting Time
Spoon or drizzle the prepared cream cheese frosting generously over the warm rested mug cake. The warmth will cause it to melt slightly creating a gooey texture. Pro tip let it melt just a bit to mimic fresh cinnamon roll glaze.
Optional Garnish
For an extra touch lightly sprinkle a tiny pinch of ground cinnamon over the frosting. It looks professional and tastes legendary.
Serve Immediately
Enjoy your Minute Keto Cinnamon Roll Mug Cake warm fresh out of the microwave and generously frosted. Grab a spoon and dig in no sharing required.

Common Mistakes to Avoid

Thinking microwave seconds are universal. They are not. Start with 60 seconds then add more if needed. Rookie move to nuke for too long.
Overmixing the batter which leads to a chewy sad cake. Stir gently.
Skimping on the swirl. If you are going to do this dessert do it right. More cinnamon love equals a better life.
Using cold cream cheese for frosting. Cold cream cheese makes the frosting lumpy. Soft is boss.
Forgetting to grease the mug if you want to invert the cake. That cake sticks like last night to your brain cells.

Alternatives & Substitutions

No almond milk on hand Use heavy cream or any unsweetened nut milk. Both work fine IMO.
No erythritol Try monk fruit or allulose but adjust quantity to taste since sweetness varies. FYI allulose can make things a touch softer.
Want dairy free Use refined coconut oil instead of butter and a dairy free cream cheese for frosting. The texture changes but the vibe stays the same.
No superfine almond flour Regular almond flour can work but expect a slightly coarser crumb. Pulse it in a food processor for a minute to make it finer.
Egg free? You can try a chia egg 1 tablespoon chia seeds plus 3 tablespoons water let sit for a few minutes but expect a denser cake. Not my favorite but it works in a pinch.

FAQ

Can I use margarine instead of butter?
Well technically yes but why hurt your soul like that? Margarine will change flavor and melt behavior. Use real butter if you can.
Will this work in an oven instead of a microwave?
Yep you can bake at 350 F in a small ramekin for about 12-15 minutes. Watch closely and test with a toothpick.
Can I double the recipe for two people?
Sure double everything and split into two mugs. Do not cram both mugs into a small microwave turntable at once it will cook unevenly.
Is this recipe freezer friendly?
The baked mug cake does not freeze great because of the frosting texture but you can freeze unfrosted cooked cake for a short time and reheat briefly.
Can I omit the cream cheese frosting?
Totally. The cake is tasty on its own but the frosting makes it feel like a cinnamon roll cheat code.
Is almond flour safe for nut allergies?
No. If you need nut free try sunflower seed flour but it can react with baking soda and discolor. Experiment cautiously.
