Mug Carrot Cake Ingredients
Here’s everything you need:
- Unsalted butter. You can use any butter, margarine or dairy-free substitute. It’s best if it’s unsalted so you can control the amount of salt added, but if you only have salted butter, just skip adding the salt later.
- All-purpose flour.
- Brown sugar. Light or dark, whichever you have on hand. I used light. Make sure it’s tightly packed when you measure.
- Baking powder.
- Cinnamon.
- Salt.
- Milk. You can use dairy or unsweetened non-dairy milk.
- Vanilla extract.
- Matchstick carrots. Or, you can just thinly slice any carrots you have on hand!
How to Make Carrot Cake in a Mug
How to Make Carrot Cake Batter for the Microwave
In a separate microwave-safe dish or ramekin, melt the butter in the microwave. Start with 30 seconds and stir. If it’s not melted after 30 seconds, continue to heat in 15-second increments, stirring in between until completely melted.
Then, set the melted butter aside until it’s time to add it to your carrot mug cake.
To a microwave-safe mug, add the flour, sugar, salt, cinnamon, and baking powder. Use a fork to stir the dry ingredients together.
Make sure to mix well, sometimes when you’re stirring the ingredients in a mug, they can get stuck to the sides
Once your butter has had a few minutes to cool, add the melted butter, vanilla extract, and milk to the mug with the dry ingredients.
Use the fork again to mix, ensuring that you get any flour that may be stuck to the sides or the bottom of the mug.
Lastly, add the carrot and fold in with your fork.
The carrots will mostly get tender in the microwave, but some pieces will retain a slight crunch, lending an awesome textural element to your mug cake. If you don’t want any crunch, dice your carrots into small bits.
Microwave and Let it Sit
Microwave your single-serving carrot cake on high for 2 minutes. Then, leave it in the microwave for another minute.
It will continue to cook slightly for that extra minute, leaving you with a warm, light, and airy mini carrot cake!
If you take it out of the microwave and notice it looks a little underdone in the center, you can heat it for an additional 15-25 seconds on high. Or you can leave it slightly underdone for a super moist texture.
Microwaving Time May Vary
Everyone’s microwave is a little bit different. My microwave is 900 watts, and on high, this carrot mug cake is perfect after 2 minutes of heating and 1 minute of sitting.
The average microwave is between 600-1200 watts. If you know your microwave is 600 watts, you will probably need an extra 10 seconds. If your microwave is 1200 watts, start with 110 seconds.
But if you’re not sure, stick with 2 minutes. It will be safe to eat and delicious either way, but just make yourself a note for next time if you feel it was slightly over or under cooked.
If you’re doubling this recipe, start with 3 minutes and 30 seconds and dip your spoon in to check if it needs any more time.
More on Mug Cakes
There Are No Eggs in Mug Cakes
You will not find eggs as an ingredient in mug cakes, simply because they are single serving. A whole egg is too much for the small amount of batter, and it’s hard to divide an egg into multiple parts.
Luckily, an egg isn’t needed! Eggs are typically used in cakes for two main reasons: to bind them together and to help with leavening.
The baking powder takes care of the leavening in the mug cake, and since the single-serving carrot cake is cooked and eaten out of the mug, we don’t have to worry about the binding factor.
Mug Cake Texture
This carrot mug cake should turn out light, airy, and moist. If your mug cake does turn out chewy, it could be because of two things: one, it could be overcooked or two, it could have too much liquid.
Make sure you measure both your dry ingredients carefully, tightly packing the brown sugar and leveling off your flour.
As for the cooking time, while microwaves do differ, 2 minutes microwaving and 1 minute sitting in the microwave is typically gives you a perfect single-serving carrot cake.
5-Minute Carrot Mug Cake
SAVE RECIPE TO COLLECTION PIN PRINT RATEIngredients
- 2 tablespoons unsalted butter (dairy or nondairy)
- ¼ cup all-purpose flour
- 2 tablespoons brown sugar, tightly packed (light or dark)
- ¼ teaspoon baking powder
- ¼ teaspoon cinnamon
- ⅛ teaspoon salt
- 3 tablespoons milk (dairy or unsweetened non-dairy)
- ½ teaspoon vanilla extract
- 1 ounce matchstick carrots (1 ounce = approx. ¼ cup matchstick carrots, tightly packed)
Instructions
- In a small microwave-safe bowl or ramekin, melt the butter in the microwave. Start with 30 seconds and stir. If it's not melted yet, continue to heat in 10-second increments, stirring in between until completely melted. Set aside to cool.
- To a standard 8-ounce mug, add the flour, brown sugar, baking powder, cinnamon, and salt. Mix with a fork until well-combined and there are no visible lumps.
- Add the milk, vanilla extract, and melted butter and stir again with the fork. Make sure to get any loose flour stuck to the sides or bottom of the mug.
- Stir in the matchstick carrots. I like to keep them whole which will make most of the carrots tender but keep a few crunchy pieces. If you want no crunch, dice your carrots into small pieces.
- Microwave on high for 2 minutes. Then, allow it to sit in the microwave for an additional 1 minute.
Pro Tips
- If after microwaving for 2 minutes and letting it sit for 1 minute in the microwave your carrot mug cake still looks underdone, you can heat it for an additional 15-25 seconds.
- If you don’t have matchstick carrots, you can julienne or slice carrots very thin to add to your mug cake.
