β 4 tablespoons sugar
β 1/8 teaspoon baking powder
β 1/8 teaspoon salt

Step-by-Step Instructions
Preparing the Dry Ingredients
First, grab a microwave-safe mug. In the mug, add:
β 4 tablespoons all-purpose flour
β 1 tablespoon cocoa powder
β 4 tablespoons sugar
β 1/8 teaspoon baking powder
β 1/8 teaspoon salt
Use a fork to mix these dry ingredients well. You want them to blend evenly. This step is key to a smooth cake.
Adding Wet Ingredients
Next, itβs time to add your wet ingredients. Pour in:
β 3 tablespoons milk (or non-dairy milk)
β 2 tablespoons peanut butter
β 1 tablespoon vegetable oil
β 1/4 teaspoon vanilla extract
Stir these together until you have a smooth batter. If you want, fold in a few chocolate chips for extra chocolatey goodness. The batter should be glossy and well mixed.
Cooking the Mug Cake
Now, place the mug in the microwave. Cook it on high for about 1 minute and 20 seconds. Keep an eye on it. Cooking times may vary based on your microwaveβs power. The cake is ready when it has puffed up. Check with a toothpick. If it comes out clean, youβre good to go! Let it cool for a minute before diving in. Enjoy right from the mug, or transfer to a plate if you prefer.
Tips & Tricks
Microwave Cooking Times
Every microwave is different. Your cooking time may vary based on wattage. A higher wattage means less cooking time. If your microwave is 1000 watts, cook for 1 minute and 20 seconds. If itβs lower, check it a bit earlier. You want the cake to puff up nicely. Always keep an eye on it to prevent overflow.
Mixing Techniques
Mixing well is key to a great mug cake. Start by blending the dry ingredients first. This helps avoid lumps. When you add wet ingredients, stir until smooth. You want a thick batter, not too runny. If you like, fold in chocolate chips last. They add extra flavor and melt beautifully.
Presentation Suggestions
How you present your mug cake makes it even more fun. Try adding a dollop of whipped cream on top. A scoop of ice cream pairs well too. For a crunchy touch, sprinkle chopped peanuts over it. These little details elevate your dessert. Enjoying your cake with a friend makes it even better!
Pro Tips
- Use Room Temperature Ingredients: Make sure your peanut butter and milk are at room temperature to ensure a smooth batter that mixes well.
- Customize Your Sweetness: Adjust the sugar level based on your sweetness preference or try using a sugar substitute for a healthier option.
- Watch Cooking Time: Microwave wattages vary, so start with 1 minute and add extra time in 10-second increments until cooked through.
- Experiment with Toppings: Try adding a drizzle of chocolate sauce, a sprinkle of sea salt, or even a scoop of ice cream for a gourmet touch.

Variations
Ingredient Substitutions
You can change some ingredients to fit your needs. If you want a gluten-free option, try almond flour or oat flour instead of all-purpose flour. For sugar, you can use honey or maple syrup. Just remember that liquid sweeteners may change the texture. If you donβt have milk, use almond milk or oat milk as a tasty choice. Each swap can give you a new taste and texture!
Flavor Additions
Looking to boost the flavor? You can add a splash of vanilla extract or a sprinkle of nutmeg. Both will enhance the mug cake without overpowering the chocolate and peanut butter. For a special twist, try adding a tablespoon of coffee or espresso. This can deepen the chocolate flavor, making it even richer!
Additional Toppings
Toppings can make your mug cake shine! Try adding fresh fruit like sliced bananas or strawberries. You can also sprinkle chopped nuts for a crunchy bite. If you love sweets, add a few sprinkles or a drizzle of chocolate sauce on top. These will not only make your cake look great but also add extra flavor!
Storage Info
Short Term Storage
To keep leftover mug cake fresh, cover it with plastic wrap or a lid. This prevents it from drying out. Store it at room temperature for one day. If you want to keep it longer, put it in the fridge. It can stay fresh for up to three days in the fridge.
Reheating Instructions
To reheat your mug cake, use the microwave. Start by removing the mug from the fridge. Heat it for about 10 to 15 seconds. Check if itβs warm enough. If not, heat it in 5-second bursts until itβs just right. Avoid overheating, as it can make the cake tough.
Freezing Recommendations
If you want to keep your mug cake for a long time, freezing is a great option. Wrap the cooled cake tightly in plastic wrap, then place it in a freezer bag. It can last up to three months in the freezer. To thaw, take it out and leave it in the fridge overnight. You can also microwave it straight from the freezer in short bursts until warm.
FAQs
Can I use a different type of nut butter?
Yes, you can use other nut butters. Almond butter works well. It gives a nice flavor. Cashew butter is another great choice. It makes the cake creamy and rich. Just keep the amount the same. You may need a bit more cocoa if the nut butter is mild.
How do I make this recipe vegan?
To make this mug cake vegan, swap the milk for non-dairy milk. Almond or soy milk are good options. Use a vegan butter instead of regular peanut butter. You can also check for vegan sugar. These small changes keep the cake tasty and plant-based.
Is this mug cake gluten-free?
To make this mug cake gluten-free, use gluten-free flour. Many brands work well in recipes. Just replace the all-purpose flour with it. The rest of the recipe stays the same. Youβll still get a delicious treat that fits your needs.
