- 1 tablespoon vegetable oil
- 1/4 teaspoon vanilla extract

Tips for Choosing Quality Ingredients
Choosing good ingredients makes your mug cake even better. Here are my tips:
- Pick fresh all-purpose flour. Check the date on the bag.
- Use high-quality cocoa powder for rich chocolate flavor.
- Ensure your baking powder is fresh. It should be active and not expired.
- Select pure vanilla extract for the best taste. Avoid artificial flavoring.
- Look for good hazelnuts. They should be crunchy, not stale.

Step-by-Step Instructions
Mixing the Dry Ingredients
Start by getting a microwave-safe mug. In this mug, combine these dry items:
- 4 tablespoons all-purpose flour
- 3 tablespoons granulated sugar
- 1 tablespoon unsweetened cocoa powder
- 1/8 teaspoon baking powder
- A pinch of salt
Use a small spoon to mix them well. You want no clumps. This step is key for a smooth cake.
Adding Wet Ingredients for Batter
Now, itβs time to add the wet items. Pour in:
- 3 tablespoons milk (or any plant-based milk)
- 2 tablespoons hazelnut spread (like Nutella)
- 1 tablespoon vegetable oil
- 1/4 teaspoon vanilla extract
Stir all these together until you see a smooth batter. Make sure there are no lumps left. The hazelnut spread gives it a creamy, rich flavor.
Cooking Time and Techniques
Place the mug in the microwave. Cook it on high for about 1 minute and 20 seconds. After that, check the cakeβs middle. If it is not set, microwave in 10-second bursts until it cooks through.
Let the mug cake cool for a minute. Enjoy it warm right in the mug. For a special touch, you can drizzle more hazelnut spread on top or add whipped cream.
Tips & Tricks
Achieving the Perfect Mug Cake Texture
To get the best texture, use a microwave-safe mug. This helps heat evenly. Mix the dry ingredients well before adding wet ones to avoid lumps. Stir until smooth for a light, fluffy cake. If the batter is too thick, add a splash more milk. This small change helps keep it moist.
Common Mistakes to Avoid
One big mistake is overcooking the cake. Start with 1 minute and 20 seconds. Check if itβs set in the middle. If not, cook in 10-second bursts. Using too much flour can also make it dense. Measure carefully to keep the right balance.
Enhancements for Richer Flavor
Add a few chocolate chips to the batter for extra chocolate goodness. You can also mix in a spoonful of coffee for a mocha twist. For a nutty crunch, use more chopped hazelnuts. These simple tweaks make your mug cake even more delicious.
Pro Tips
- Use Room Temperature Ingredients: Ensuring your milk and oil are at room temperature will help the batter mix more smoothly, resulting in a better texture.
- Adjust Microwave Time: Microwaves can vary in power, so keep an eye on your mug cake. Start checking for doneness at the 1-minute mark to prevent overcooking.
- Experiment with Add-ins: Feel free to add chocolate chips, dried fruits, or different nuts to customize the mug cake to your taste.
- Presentation Matters: To elevate your dessert, serve the mug cake with a drizzle of chocolate sauce or a scoop of ice cream for an indulgent treat.

Variations
Alternate Nut Spreads
You can switch hazelnut spread for other nut spreads. Try almond or peanut butter for a twist. Each nut spread brings its own flavor. Almond spread offers a light, nutty taste. Peanut butter adds a rich, creamy texture. Feel free to experiment and find your favorite!
Flavor Add-Ins
You can add fun flavors to your mug cake. Chocolate chips bring extra sweetness and texture. A pinch of espresso powder gives a coffee kick. You can also use cinnamon for a warm spice. Mix and match these flavors to make your cake special.
Adjusting for Dietary Preferences
If you need gluten-free options, substitute the flour. Use a gluten-free flour blend for the best results. For a vegan version, swap milk with plant-based milk. Replace the hazelnut spread with a vegan alternative. These changes let everyone enjoy this treat!
