- Chocolate Caramel Mug Cake – The Perfect Dessert For One Recipe
Watch the short video — filmed in my living room because we had no kitchen at the time — for an easy visual guide.
For years I dismissed microwave mug cakes on Pinterest as dense and rubbery. Instead I focused on quick single-serve desserts like peach and almond cake or no-bake Snickers bites. I was wrong: when done right mug cakes can be light and fluffy, rising in the microwave almost like a mini soufflé. Adding a few Rolos gives a molten caramel center, and a scoop of ice cream makes it even better.

I mixed the batter in a jug because I’m messy, then poured it into a mug. If you prefer, you can mix directly in the mug to reduce washing up — a single cup, spoon and fork is about as no-fuss as dessert gets.

I’ve just started a YouTube channel and plan to add more recipe videos soon. If you enjoy the video and want to subscribe, I’d be grateful — thank you to anyone who does.
Pro tip: To make this gluten free, swap the plain (all-purpose) flour for a plain gluten free flour blend — it works well.

Chocolate Caramel Mug Cake – The Perfect Dessert For One
Ingredients
- 2 tbsp unsalted butter
- 2 tbsp chocolate chips
- 3 tbsp plain / all-purpose flour
- 2 tbsp cocoa powder
- ¼ tsp baking powder
- 3 tbsp light brown sugar
- 2 tbsp milk
- ¼ tsp vanilla extract
- Pinch of salt
- 1 small egg, lightly whisked
- 4 Rolos or other chocolate-covered caramels
To serve:
- Chocolate chips and confectioners’ sugar
Instructions
- Place the butter and chocolate chips in a jug and melt in the microwave (about 30–60 seconds), stirring until smooth.
- Add the flour, cocoa powder, baking powder, sugar, milk, vanilla extract, a pinch of salt and the whisked egg to the jug. Whisk until well combined.
- Pour the batter into a mug and press the 4 Rolos into the centre.
- Microwave for 90–110 seconds, until the cake has risen over the rim and is set on top (avoid overcooking to keep it light).
- Remove carefully — it will be hot — and top with extra chocolate chips and a dusting of confectioners’ sugar. Serve with ice cream if you like.
