Start by gathering all your ingredients. Ensure you have a microwave-safe mug ready because this is where the magic happens. It’s crucial that the mug is large enough to allow the cake to expand.
In a small bowl, whisk together the Nutella, egg, cocoa powder, sugar, and a pinch of sea salt. Mix well until the ingredients are combined and the batter is smooth. You should see a nice glossy texture forming as you whisk.
Once the mixture is ready, pour it into your microwave-safe mug. Make sure to scrape down the sides of the bowl to get all the batter into the mug. The batter should fill the mug to about halfway to prevent overflow during cooking.
Microwave the mug for about 60 to 75 seconds. Keep an eye on it as it cooks—the cake will rise quite a bit, so don’t be alarmed! If you prefer a slightly firmer texture, you can microwave for up to 90 seconds.
When it’s done, carefully remove the mug from the microwave. It will be hot, so use oven mitts or a towel! Let it cool for a few minutes. The cake will settle down after being taken out, which is completely normal.
If you like, you can add an extra dollop of Nutella on top for an extra touch of indulgence. This will melt slightly, creating a delicious gooey topping.
Now, dig in! Enjoy your Nutella Mug Cake straight from the mug. It’s perfect for a quick dessert or a late-night snack!
Don’t forget to savor every bite—share with a friend or keep it all to yourself. You deserve this little treat!
