Step-by-Step Instructions
Preparation Overview
Making a chocolate hazelnut mug cake is simple. You need just a few minutes and one mug. Gather your ingredients and tools before you start. You’ll need a microwave-safe mug, a whisk, and a spoon.
Detailed Cooking Steps
1. Mix Dry Ingredients: In your mug, add 4 tablespoons of all-purpose flour, 4 tablespoons of granulated sugar, 2 tablespoons of cocoa powder, 1/8 teaspoon of baking powder, and 1/8 teaspoon of salt. Whisk them until they blend well.
2. Add Wet Ingredients: Now, pour in 3 tablespoons of milk, 2 tablespoons of hazelnut spread, 2 tablespoons of vegetable oil, and 1/4 teaspoon of vanilla extract. Mix everything until smooth. Make sure there are no lumps.
3. Optional Hazelnuts: If you like crunchy bits, fold in 2 tablespoons of chopped hazelnuts into the mixture. This step adds texture and flavor.
4. Microwave the Cake: Place your mug in the microwave. Cook on high for 1 minute. Keep an eye on it to prevent overflow. If it’s not fully set, microwave in 15-second bursts until done.
5. Cool and Serve: Once cooked, let your mug cake cool for about a minute. This helps avoid burns when you dig in.
Cooking Time and Tips
The total time to make this dessert is about 10 minutes. Prep takes 5 minutes. For the best results, watch your cake while it cooks. If you want more flavor, serve it warm with extra hazelnut spread and a sprinkle of chopped hazelnuts. A scoop of vanilla ice cream on the side makes it even better! Enjoy your perfect treat!
Tips & Tricks
How to Achieve the Perfect Mug Cake Texture
To get the best texture, use fresh ingredients. Old baking powder can ruin your cake. Mix the dry ingredients well before adding wet ones. This helps avoid lumps. When you add the milk and hazelnut spread, stir gently. Don’t overmix; a few lumps are fine. Microwave in short bursts to prevent overflow.
Common Mistakes to Avoid
One mistake is using the wrong mug size. Choose a large mug to give the cake room to rise. Another common error is not watching the time. Overcooking makes the cake dry. If your cake is too wet, it needs more time. Start with 1 minute, then check in 15-second increments.
Recommended Serving Suggestions
Serve your mug cake warm for the best taste. Top it with a scoop of vanilla ice cream for a creamy contrast. Drizzle more hazelnut spread on top for extra flavor. Add chopped hazelnuts for a nice crunch. You can also enjoy it with a cup of coffee or tea.

Variations
Flavor Customizations
You can change the taste of your chocolate hazelnut mug cake easily. Try adding a pinch of cinnamon for warmth. A dash of espresso powder gives it a coffee kick. If you love orange, mix in some orange zest. You can even swap hazelnut spread for peanut butter for a nutty twist. Feeling adventurous? Add a few chocolate chips!
Dietary Substitutes
Need to make this dessert fit your diet? You can use almond flour instead of all-purpose flour for a gluten-free option. For a lower sugar treat, try a sugar substitute like stevia. You can replace milk with almond or oat milk for a dairy-free version. If you want a vegan mug cake, use mashed banana instead of egg and skip the milk.
Using Different Baking Tools
You don’t have to limit yourself to a mug! You can use a small bowl or ramekin instead. Just make sure it’s microwave-safe. The cooking time might change a little, so keep an eye on it. If you have a mini oven, use that too! Just adjust the time based on your oven’s settings. Enjoy experimenting with these variations!
Storage Info
How to Store Leftovers
After you enjoy your chocolate hazelnut mug cake, you might have some left. To store it, cover the mug with plastic wrap or place it in an airtight container. This keeps it fresh and moist. Store it in the fridge for up to two days.
Reheating Instructions
To reheat the mug cake, take it out of the fridge. If it is in a plastic container, transfer it back to a microwave-safe mug. Heat it in the microwave for about 10 to 15 seconds. Check it to see if it is warm. If not, heat it in 5-second bursts. You want it warm, not hot.
Freezing the Mug Cake
You can freeze the mug cake if you want to save it for later. Let it cool completely first. Wrap it tightly in plastic wrap and then foil. This helps prevent freezer burn. Store it in the freezer for up to one month. When you want to eat it, thaw it in the fridge overnight. Reheat it in the microwave when you’re ready to enjoy!
FAQs
How do I make a mug cake without a microwave?
You can make a mug cake on the stove. Use a small pot with a lid. Fill the pot with a little water, then place a heat-safe mug inside. Make sure the water does not touch the batter. Cover the pot and heat it on low. Cook for about 10-15 minutes. Check the cake with a toothpick. If it comes out clean, it’s done. This way, you still get a warm treat!
Can I use other types of spreads instead of hazelnut?
Yes, you can! Try peanut butter, almond butter, or any chocolate spread. Each will bring a new taste to your mug cake. If you use a thicker spread, you may need to add a little extra milk. This keeps the cake moist and tasty. Feel free to experiment with your favorite flavors!
Is it possible to make this mug cake gluten-free?
Absolutely! Swap the all-purpose flour for a gluten-free blend. Many brands offer great options that work well in baking. Just check that the blend includes a binding agent, like xanthan gum. This helps your mug cake hold together. You can still enjoy the rich chocolate and hazelnut flavor without gluten.
