To make this delicious chocolate peanut butter mug cake, you need simple ingredients. First, gather your all-purpose flour. This forms the base of your cake. Next, grab sugar for sweetness. Cocoa powder adds rich chocolate flavor. Baking powder helps the cake rise.

If you love extra chocolate, toss in some chocolate chips. They melt beautifully and make each bite more enjoyable. With these ingredients on hand, you are ready to create a quick and satisfying treat!

Step-by-Step Instructions
Preparation of Dry Ingredients
In a microwave-safe mug, combine the following dry ingredients:
β 4 tablespoons all-purpose flour
β 4 tablespoons sugar
β 2 tablespoons cocoa powder
β 1/4 teaspoon baking powder
β A pinch of salt
Stir the dry mix well. This step is key to avoid lumps. Make sure everything blends smoothly. A good mix means a fluffy cake!
Mixing Wet Ingredients
Now, itβs time to add the wet ingredients. Pour in:
β 3 tablespoons milk
β 2 tablespoons peanut butter
β 1 tablespoon vegetable oil
β 1/4 teaspoon vanilla extract
Mix thoroughly until you achieve a smooth batter. You want no dry flour left. If you like extra chocolate, fold in some chocolate chips now. They add a rich touch.
Microwave Cooking
Microwave the mug on high for about 40 to 60 seconds. Watch closely. Cooking times can differ by microwave. You want the cake to rise and set. It should look slightly moist in the center.
Let it cool for a minute before enjoying. The cake is best warm.
Tips & Tricks
Achieving the Perfect Mug Cake
To make the best mug cake, use a microwave with 800 to 1000 watts. This power works well for even cooking. Start by microwaving for 40 seconds. Check the cake often to avoid overcooking. If it rises too high, reduce the time in the next round. You want it fluffy but not spilling over.
Serving Suggestions
Get creative with toppings! Try whipped cream, chocolate syrup, or a scoop of ice cream. You can also add nuts or fresh fruit. Mix-ins like chocolate chips give you extra flavor. Enjoy your mug cake warm for the best taste. You can even pair it with coffee or tea for a cozy treat.
Pro Tips
- Use a Large Mug: A larger mug allows for more expansion of the cake, preventing overflow in the microwave.
- Check Microwave Wattage: Cooking times may vary; adjust the time according to your microwaveβs wattage for the best results.
- Experiment with Toppings: Try different toppings like sliced bananas, crushed nuts, or yogurt to customize your mug cake experience.
- Let it Cool: Allowing the cake to cool for a minute enhances the flavor and makes it easier to eat.

Variations
Alternate Flavor Options
You can change up the peanut butter in your mug cake. Try almond butter or sun butter. These swaps add new flavors and keep things exciting. You can also add mix-ins. Consider nuts like walnuts or almonds for crunch. You could also toss in some fruit. Slices of banana or berries work well. These additions can make your cake even more tasty and fun.
Dietary Substitutions
If you need a gluten-free version, swap the all-purpose flour for a gluten-free blend. Many blends work just as well. For a vegan mug cake, use plant-based milk, like almond or soy milk. Replace the egg with a flaxseed meal or applesauce. This way, everyone can enjoy this treat, no matter their diet!
Storage Info
Storing Leftovers
To keep your chocolate peanut butter mug cake fresh, cover it tightly. I recommend using plastic wrap or a small plate. This prevents air from drying it out. Store it at room temperature for one day. If you want to save it longer, put it in the fridge. In the fridge, it lasts about three days.
Reheating Recommendations
To reheat your mug cake, the microwave is the best choice. Heat it in short bursts of ten seconds. This helps keep the texture soft and moist. If it feels dry, add a splash of milk before reheating. Stir it gently after heating to mix the moisture back in. Enjoy your warm treat!
FAQs
Can I make this mug cake without a microwave?
Yes, you can! If you donβt have a microwave, you can use an oven. Preheat your oven to 350Β°F (175Β°C). Pour the batter into a small oven-safe dish. Bake for about 15 to 20 minutes. Check for doneness by inserting a toothpick. If it comes out clean, itβs ready.
How do I make this mug cake healthier?
You can make simple swaps for a healthier treat. Use whole wheat flour instead of all-purpose flour. This adds fiber. Replace sugar with a natural sweetener like honey or maple syrup. You can also use unsweetened applesauce for part of the oil. This cuts calories.
Can I double the recipe?
Absolutely! To double the recipe, use an 8-ounce mug or a small bowl. Just multiply each ingredient by two. Adjust the cooking time too. A larger portion may take a bit longer in the microwave. Start with 1 minute and check until done.
What if my mug cake is too dry?
If your mug cake turns out dry, it may need more moisture. Next time, add a little more milk or peanut butter. You can also try cooking for less time. If itβs already cooked, add a drizzle of melted chocolate or a scoop of ice cream. This adds moisture and flavor.
