To make a Chocolate Peanut Butter Mug Cake, you need simple ingredients. This recipe uses common items you may have at home. First, grab your flour, sugar, and cocoa powder. These will form the cake base.
Next, youβll need baking powder and salt. Baking powder helps the cake rise. Salt brings out the flavors.
For the wet mix, gather milk, peanut butter, and vegetable oil. Milk adds moisture, while peanut butter gives it a rich taste. The vegetable oil keeps the cake soft.
Finally, add vanilla extract for flavor. If you want extra chocolate, toss in some chocolate chips. They melt and make the cake even better!
These ingredients come together to create a delicious treat in just a mug. No need for fancy tools or equipment. Just mix, microwave, and enjoy!

Step-by-Step Instructions
Preparation of Dry Ingredients
In a microwave-safe mug, start by adding:
- 4 tablespoons all-purpose flour
- 4 tablespoons granulated sugar
- 2 tablespoons unsweetened cocoa powder
- 1/8 teaspoon baking powder
- 1/8 teaspoon salt
Mix these dry ingredients well with a fork. I like to make sure there are no lumps. This helps the cake rise better.
Mixing Wet Ingredients
Next, itβs time to add the wet ingredients. Pour in:
- 3 tablespoons milk (dairy or non-dairy)
- 2 tablespoons peanut butter
- 1 tablespoon vegetable oil
- 1/4 teaspoon vanilla extract
Stir until the batter is smooth. Scrape the bottom and sides of the mug to mix everything well. If you want more chocolate, fold in a few chocolate chips now.
Cooking the Mug Cake
Now, place your mug in the microwave. Cook on high for 1 minute. Microwave times can vary, so watch it closely. If the cake is not set, microwave it for 10-second bursts until it rises and is firm in the middle. Let it cool for a minute before digging in. Enjoy straight from the mug, or top with whipped cream or chocolate syrup if you like!
Tips & Tricks
Achieving the Perfect Texture
To get the best texture in your mug cake, watch the cooking time. Microwave it for one minute, but keep checking. Every microwave is different. If it isnβt set in the middle, cook in 10-second bursts. This way, you avoid overcooking. A perfectly cooked mug cake should be soft and fluffy.
Customizing Your Mug Cake
You can mix things up with your mug cake. Add toppings like whipped cream, nuts, or fresh fruit. Want more chocolate? Toss in chocolate chips before cooking. You can even stir in some crushed cookies for crunch. The choice is yours!
Troubleshooting Common Issues
If your cake overflows, try using a bigger mug next time. The batter can rise quite a bit. If your cake is undercooked, simply microwave it longer, as mentioned before. Check for doneness by looking for a set center. If it jiggles too much, it needs more time. Enjoy your delicious creation!
Pro Tips
- Use a Larger Mug: To prevent overflow during cooking, choose a mug that can hold at least 12 ounces.
- Experiment with Nut Butters: Try almond or cashew butter instead of peanut butter for a unique flavor twist.
- Check Microwave Power: Different microwaves vary in wattage; adjust cooking time accordingly to avoid undercooking or burning.
- Customize Toppings: Enhance your mug cake with toppings like sliced bananas, crushed nuts, or a scoop of ice cream for a delightful treat.

Variations
Flavor Variations
You can change the flavor of your mug cake easily. Swap out peanut butter for almond butter. This gives a nutty twist. You can also try Nutella for a rich, chocolatey taste. Both options add a fun spin to the cake.
Dietary Alternatives
If you need gluten-free options, use a gluten-free flour blend. Make sure it works for baking. For dairy-free needs, switch to non-dairy milk like almond or oat milk. These changes keep the cake tasty and safe for different diets.
Serving Suggestions
Pair your mug cake with a scoop of ice cream for a treat. Vanilla or chocolate work best. You can also add fresh fruits like bananas or strawberries on top. These add color and flavor. Enjoy your mug cake in different ways to keep it exciting!
Storage Info
Storing Leftovers
If you have any leftover mug cake, store it in an airtight container. You can refrigerate it for up to two days. When you want to enjoy it again, heat it in the microwave for about 10 to 15 seconds. Check the cake after heating to make sure itβs warm all the way through.
Best Practices for Single-Serving Desserts
Mug cakes taste best when fresh. They can dry out quickly after cooking. When you enjoy a mug cake right away, it stays soft and moist. If you want to share, make individual servings. This way, everyone gets a warm, fluffy treat. Plus, itβs fun to make them together!
FAQs
Can I make this mug cake without a microwave?
Yes, you can bake this mug cake in the oven. Preheat your oven to 350Β°F (175Β°C). Pour the batter into an oven-safe mug or ramekin. Bake for about 15-20 minutes. Check it often to avoid overbaking. The cake should rise and look set.
How do I know when the mug cake is done?
You can tell the mug cake is done by looking for a few signs. First, it should rise and not look wet on top. Second, insert a toothpick in the center. If it comes out clean, itβs ready. If itβs wet, give it more time in the microwave.
Can I double the recipe?
Yes, you can double the recipe. Just use a bigger mug or two separate mugs. Youβll need to adjust the cooking time. Start with 1 minute for each mug. Then, check if it needs more time. Cook in 10-second bursts if needed.
