Watch out mug cake lovers, this might just become your new go-to! This Cinnamon Nut Swirl Mug Cake is like a short cut cinnamon roll with no kneading, no rising, and no rolling required! It’s the perfect quick fix for when you need just a couple bites of cinnamon-y sweetness without having a whole pan of cinnamon rolls staring you down all day. Or when you don’t want to pay $5 for a cinnamon roll the size of your head. Because while I love cinnamon rolls that big, I don’t need cinnamon rolls that big. 😅
What’s with Mug Cakes, Anyway?
Mug cakes certainly aren’t for everyone, but if you’re the type of person that doesn’t like to keep sweets on hand, but does have the occasional sweet craving, mug cakes are the perfect single-serving fix. They take just enough work that I’m not tempted to make them ever day, but they’re certainly easier than making a whole dessert or going out to buy a single portion of something. They do also require a pantry stocked with basic baking ingredients, like flour, sugar, baking powder, etc.
Do I Have to Use a Microwave?
Yes, this recipe is designed specifically for the microwave. Ovens cook at a much slower pace, so this recipe would have to be tested and adjusted to compensate for the difference. Unfortunately I have not tested this recipe for conventional ovens.
Can I Use Non-Dairy Milk?
Because the milk is such a small quantity in this recipe, I do think you could get away with using a non-dairy milk, like almond or soy. You may also be able to use a non-dairy butter substitute as well, as long as it does not contain too high of a percentage of water. I have not tested this recipe with either of these non-dairy ingredients, so this is just my best guess.
Take the pricing breakdown below with a grain of salt. This recipe uses super small quantities of ingredients that already cost pennies at normal volumes, so the calculations are definitely more in the range of a general estimate.
Cinnamon Nut Swirl Mug Cake
Mug Cake Batter
- 1/4 cup all-purpose flour ($0.03)
- 1 Tbsp brown sugar ($0.04)
- 1/4 tsp baking powder ($0.01)
- 1/8 tsp salt ($0.01)
- 1/8 tsp cinnamon ($0.02)
- 1 Tbsp chopped pecans or walnuts (optional) ($0.16)
- 1/2 Tbsp butter, melted ($0.03)
- 2 Tbps milk ($0.04)
Cinnamon Butter Swirl
- 1/2 Tbsp butter, melted ($0.03)
- 1 tsp brown sugar (0.02)
- 1/2 tsp cinnamon ($0.05)
- 1 Tbsp powdered sugar ($0.01)
- 1/2 tsp milk ($0.01)
- In a small mug (about 1 cup volume), stir together the dry ingredients for the mug cake batter: flour, brown sugar, baking powder, salt, cinnamon, and chopped pecans.
- Add the melted butter and milk to the dry ingredients in the mug and stir until a thick batter forms.
- In a separate small bowl or mug, melt the butter for the cinnamon butter swirl (about 15 seconds in the microwave). Stir the brown sugar and cinnamon into the melted butter.
- Drizzle the cinnamon butter swirl over the mug cake batter, then gently fold them together until they are only about half mixed. There should be thick ribbons of the cinnamon butter swirl throughout the batter.
- Microwave the mug cake for 45-55 seconds (for a 1100 watt microwave, cooking time will vary with microwave wattage). The mug cake will create quite a bit of steam as it cooks, so don't be alarmed. Let the mug cake cool for 1-2 minutes.
- While the mug cake is cooling, stir together the powdered sugar and milk for the icing, using the same small bowl used for the cinnamon butter swirl. The residual cinnamon in the bowl will flavor the icing.
- Drizzle the icing over the mug cake and enjoy while it is still warm.

How to Make Cinnamon Nut Swirl Mug Cake – Step by Step Photos
Start by adding the dry ingredients for the mug cake batter to a small mug (about 1 cup volume): 1/4 cup all-purpose flour, 1 Tbsp brown sugar, 1/4 tsp baking powder, 1/8 tsp salt, 1/8 tsp cinnamon, and 1 Tbsp chopped pecans or walnuts. Stir these ingredients together until they are well combined.
Next, add 1/2 Tbsp melted butter (microwave butter for about 15 seconds in a separate bowl) and 2 Tbsp milk.
Stir the wet and dry ingredients together until they form a thick batter.
In a separate small bowl, melt another 1/2 Tbsp butter (microwave 15 seconds or so), then stir in 1 tsp brown sugar and 1/2 tsp cinnamon. This is the cinnamon butter swirl.
Drizzle the cinnamon butter over the mug cake batter, then gently fold them together, only until they are about half mixed. You want thick ribbons of the cinnamon butter throughout the batter.
Microwave the mug cake for 45-55 seconds (this is the time for an 1100 watt microwave, your time may vary with the wattage of your microwave). The mug cake will steam quite a bit as it cooks, so don’t be alarmed. Let the mug cake cool for 1-2 minutes.
While the mug cake is cooling, make the icing. Use the same bowl used to make the cinnamon butter swirl. The residual cinnamon in the bowl will flavor the icing. Stir together 1 Tbsp powdered sugar with 1/2 tsp milk until a thick icing forms.
Drizzle the icing over the Cinnamon Nut Swirl Mug Cake.
Enjoy while still warm!
Do you need to adjust the cooking time if making 2 at the same time?
Hi Melissa- I wouldn’t do two at the same time, as they might not cook evenly. But if you want to try it, then yes you should adjust the cooking time. Unfortunately, since we haven’t done it that way, I can’t tell you how much you should adjust the time. Let us know the results! XOXO -Monti
Do you need to cover the mug in the microwave?
You shouldn’t need to cover it! ~Marion :)
