Step‑by‑Step Instructions for Keto Cinnamon Roll Mug Cake
Step 1: Melt the Butter
Begin by placing 1 tablespoon of butter in a microwave-safe mug or ramekin. Microwave it on high for about 20–30 seconds until fully melted. The butter should be bubbling slightly, creating a rich base for your Keto Cinnamon Roll Mug Cake.
Step 2: Combine the Dry Ingredients
Next, add 1/4 cup of almond flour, 1 egg, 1 teaspoon of cinnamon, 1/2 teaspoon of baking powder, and 1 tablespoon of stevia powder into the melted butter. Stir these ingredients together well until you have a smooth, thick batter, ensuring there are no lumps for a delightful texture.
Step 3: Microwave the Cake
Once well combined, microwave the mug cake mixture on high for 90 seconds. The cake should rise and look set in the center when done. Carefully remove the mug from the microwave, as it will be hot, and let it sit for a moment to cool slightly.
Step 4: Loosen and Plate the Cake
Using a small knife, gently run it around the edges of the cake to loosen it. Invert the mug onto a plate, allowing the Keto Cinnamon Roll Mug Cake to fall out gently. It should come out smoothly, revealing its fluffy texture and delicious cinnamon aroma.
Step 5: Prepare the Glaze
In a separate small bowl, melt an additional tablespoon of butter for the glaze in the microwave for about 20 seconds. Stir in 1/2 teaspoon of cinnamon and 1 tablespoon of stevia powder until well combined. This will create a gooey, irresistible glaze for your mug cake.
Step 6: Melt the Frosting
For the cream cheese frosting, place 2 tablespoons of cream cheese in a small ramekin and microwave for about 20 seconds until softened. Stir in 1 tablespoon of stevia powder until the mixture is creamy and smooth, ready to be spread over the warm cake.
Step 7: Assemble and Serve
Drizzle the buttery glaze over your Keto Cinnamon Roll Mug Cake, ensuring it seeps into the warm cake. Then, spread the cream cheese frosting generously on top. Serve immediately for the best taste and enjoy the comforting flavors of this quick and easy dessert!

Expert Tips for Keto Cinnamon Roll Mug Cake
• Microwave Variability: Adjust cooking time based on your microwave’s wattage; start with 60 seconds and add time as needed to avoid overcooking.
• Ingredient Precision: Use a kitchen scale for measuring almond flour accurately, as too much can lead to a dense cake texture.
• Flavor Boost: Enhance flavor by adding a pinch of nutmeg or vanilla extract to the cake batter, making your Keto Cinnamon Roll Mug Cake even more decadent.
• Glaze Texture: If your glaze is too thick, add a tiny splash of almond milk for a smoother pour; ensure it’s drizzling consistency for a delicious finish.

Make Ahead Options
If you’re a busy home cook looking to save time, preparing components of the Keto Cinnamon Roll Mug Cake in advance is a fantastic option! You can mix the dry ingredients (almond flour, cinnamon, baking powder, and stevia) and store them in an airtight container for up to 3 days. This not only streamlines the process but also ensures that your ingredients are perfectly prepped. Additionally, you can melt the butter for the glaze ahead of time and refrigerate it, just remember to warm it back up before serving. When you’re ready to indulge, simply combine the prepped ingredients, microwave for 90 seconds, and drizzle with the warm glaze and cream cheese frosting for a comforting, delightful treat that’s just as scrumptious as if it were made fresh!
Proper Storage for Keto Cinnamon Roll Mug Cake
Fridge: Store any leftovers in an airtight container in the fridge for up to 2 days to keep the cake fresh and moist.
Freezer: For longer storage, you can freeze the mug cake without frosting for up to 1 month. Wrap it tightly in plastic wrap and then place it in a freezer bag.
Reheating: To enjoy your Keto Cinnamon Roll Mug Cake, reheat in the microwave for about 30-40 seconds, ensuring it’s warmed through. Add fresh glaze or frosting afterward for a delightful treat!
It’s best to enjoy this cake fresh, but these tips will help you get the most out of your keto dessert experience!

3-Minute Keto Cinnamon Roll Mug Cake Recipe FAQs
How do I select the best ingredients for the Keto Cinnamon Roll Mug Cake?
Absolutely! The key to a successful Keto Cinnamon Roll Mug Cake starts with fresh ingredients. For the butter, make sure it’s not too soft or too cold to avoid uneven melting. Use finely ground almond flour for the best texture—coarser flour might make the cake grainy. When selecting cinnamon, opt for ground cinnamon that has a rich aroma, as spices can lose potency over time.
How should I store leftovers of the Keto Cinnamon Roll Mug Cake?
If you happen to have leftovers (which is rare with this yummy mug cake!), drop them into an airtight container and pop them in the fridge. They will keep well for about 2 days. To enjoy later, simply reheat in the microwave for 30 to 40 seconds until warmed through.
Can I freeze the Keto Cinnamon Roll Mug Cake?
Yes, you can definitely freeze this mug cake! To do so, let it cool completely before wrapping it tightly in plastic wrap. Next, place it in a freezer bag or an airtight container. It will stay fresh for up to 1 month. When you’re ready to enjoy it, just thaw in the fridge overnight and reheat to your preference.
What should I do if my mug cake comes out dense or rubbery?
Very! If your Keto Cinnamon Roll Mug Cake turns out dense or rubbery, a couple of adjustments can help. First, check the accuracy of your ingredient measurements, especially the almond flour. Too much can make the cake heavy. Also, be mindful of the microwave cooking time; overcooking can lead to a rubbery texture. Start with 60 seconds and add time in small increments if needed until it’s set.
Are there any dietary considerations for the Keto Cinnamon Roll Mug Cake?
Absolutely! This recipe caters well to keto and low-carb diets, but if you’re making it for someone with dietary restrictions, there are a few substitutions to consider. For a nut-free version, swap almond flour for sunflower seed flour. If someone is dairy-free, use coconut oil instead of butter and Greek yogurt instead of cream cheese in the frosting. Don’t forget to choose a sweetener that fits their dietary needs—stevia works great for those watching sugar intake!
What if my frosting is too thick for the Keto Cinnamon Roll Mug Cake?
Very good question! If you find your cream cheese frosting is too thick, simply add a teaspoon of almond milk or water to thin it out. Stir well and it should reach a nice, spreadable consistency that’s perfect for drizzling over your mug cake. Enjoy the process, and feel free to adjust flavors to your liking!
