Ingredients You’ll Need for Caramel Mug Cake
- ½ cup self-rising flour
- ¼ cup brown sugar
- A pinch of salt
- 1 egg
- ¼ cup milk
- ½ teaspoon vanilla
- 3 tablespoons melted unsalted butter
How to Make Caramel Mug Cake
- Mix the dry ingredients. In a medium bowl, combine the self-rising flour, brown sugar, and a pinch of salt.
- Add the wet ingredients. Stir in the egg, milk, vanilla, and melted butter. Mix until just combined—don’t overdo it! We want a tender cake, not a chewy one.
- Fill your mugs. Divide the batter between two mugs, making sure they’re only about halfway full. Trust me, this cake rises fast in the microwave!
- Cook to perfection. Microwave each mug for 1½ minutes. The top should be firm but still have a soft, almost gooey center when you press on it lightly.
And that’s it! Your Caramel Mug Cake is ready to dig into.

Serving Suggestions:
Now, let’s talk about toppings because, honestly, what’s cake without a little extra love on top?
If you’re anything like me, a scoop of vanilla ice cream is the go-to. The cold, creamy ice cream melting into the warm cake—chef’s kiss. But if you want to get creative, warm apple pie filling or even a drizzle of caramel sauce can take this cake to the next level. Feeling extra indulgent? Why not go for both?
Make It Gluten-Free:
Want a gluten-free option? No problem! Just swap in your favorite gluten-free flour and add ⅛ teaspoon baking powder. Same delicious taste, no gluten.
Caramel Mug Cake Recipe: FAQ
Can I make this mug cake without self-rising flour?
Yes! If you don’t have self-rising flour, you can make your own. Just mix ½ cup of all-purpose flour with ½ teaspoon of baking powder and a pinch of salt. That will do the trick.
How do I know when the mug cake is done?
The cake should feel firm on top but still slightly soft when you press it. If it looks wet or too jiggly in the center, give it another 10–15 seconds in the microwave. Microwave times can vary, so keep an eye on it!
Can I add caramel sauce to the batter?
Absolutely! If you want extra caramel flavor, drizzle a little caramel sauce into the batter before microwaving. You can also swirl it in for a marbled effect.
Can I make this recipe vegan?
Yes! Just swap the egg for a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water), use plant-based milk like almond or oat, and substitute vegan butter for the regular butter.
What’s the best way to store leftovers?
Mug cakes are best enjoyed fresh out of the microwave. If you do have leftovers, cover the mug tightly with plastic wrap and store it in the fridge for up to 1 day. When you’re ready to eat, reheat it in the microwave for about 15–20 seconds.
Can I double this recipe?
Definitely! Just double the ingredients and divide the batter among more mugs. Make sure to cook each mug one at a time for even results.
Can I use other flavors instead of caramel?
Yes, this recipe is super flexible! You can swap out the caramel for chocolate chips, a spoonful of Nutella, or even peanut butter. The possibilities are endless.
What if I don’t have a microwave?
No microwave? No problem! You can bake your mug cake in the oven at 350°F (180°C) for about 10–12 minutes. Just make sure to use oven-safe mugs.
Can I make this cake healthier?
Sure thing! You can use coconut sugar instead of brown sugar, almond flour instead of self-rising flour, and unsweetened almond milk to lighten it up. Keep in mind, the texture may be slightly different.
Can I add mix-ins?
Yes! Feel free to throw in a handful of chocolate chips, chopped nuts, or even dried fruit to make this mug cake your own.
There you have it, a warm and delicious Caramel Mug Cake in less time than it takes to watch a YouTube video.
