For this Chocolate Peanut Butter Mug Cake, you will need simple and easy-to-find items. Start with the dry goods first. Use all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, and a pinch of salt. These create the base of your cake.
Next, grab your liquid ingredients. You will need milk, peanut butter, vegetable oil, and vanilla extract. These add moisture and flavor to the cake. Peanut butter gives it that rich, nutty taste that pairs perfectly with chocolate.
If you want to make your cake even more special, consider adding chocolate chips. They melt into the cake and create gooey pockets of chocolate. You can also think about toppings like whipped cream or crushed peanuts for extra crunch.
Gathering these ingredients is quick and easy. Make sure to measure them accurately for the best results. With everything ready, you are set to make a delicious mug cake in just a few minutes!

Step-by-Step Instructions
Preparation of the Dry Mixture
In a large mug, start by adding the dry ingredients. Put in 4 tablespoons of all-purpose flour, 4 tablespoons of sugar, 2 tablespoons of cocoa powder, 1/8 teaspoon of baking powder, and 1/8 teaspoon of salt. It’s key to mix these dry ingredients well. This helps avoid lumps. A good stir ensures even flavor in every bite.
Incorporate Wet Ingredients
Now, let’s add the wet ingredients. Pour in 3 tablespoons of milk, 2 tablespoons of peanut butter, 2 tablespoons of vegetable oil, and 1/4 teaspoon of vanilla extract. I like using a fork or a small whisk for this step. Mix until the batter is smooth. Make sure there are no lumps. The smooth batter makes a big difference in the cake’s texture.
Microwave Cooking
Next, it’s time to cook the cake. Microwave it on high for about 1 minute and 30 seconds. Keep an eye on it while it cooks. Cooking times can change based on your microwave’s power. The cake should rise and look set, but not dry. If you see it puffing up, that’s a good sign!
Tips & Tricks
Achieving the Perfect Mug Cake
To make a great mug cake, avoid common mistakes. One big mistake is not mixing well. Make sure to combine all dry ingredients before adding liquids. This helps avoid lumps. Another mistake is using the wrong mug size. Use a mug that holds at least 12 ounces. This gives the cake space to rise.
Add-Ins and Customizations
Want to spice it up? You can add different flavors. Try a bit of cinnamon or a sprinkle of sea salt. You can also use other nut butters. Almond butter or cashew butter can give new tastes. Experiment and find your favorite!
Serving Suggestions
Present your mug cake with flair. Serve it right in the mug for a cozy look. Top it with whipped cream or ice cream for a treat. Pair your mug cake with milk or coffee. This makes the perfect sweet snack!
Pro Tips
- Use a Larger Mug: Make sure to use a 12 oz or larger mug to prevent overflow while the cake rises in the microwave.
- Check Microwave Power: Since microwaves vary in strength, start with 1 minute and 30 seconds and add additional time in 10-second intervals if needed.
- Customize Your Flavor: Feel free to experiment by adding a pinch of cinnamon or a splash of espresso powder for a deeper flavor profile.
- Perfect Toppings: Top with whipped cream, ice cream, or a drizzle of chocolate sauce for an indulgent finish to your mug cake.

Variations
Different Flavor Options
You can have fun with this mug cake. Try adding chocolate chips for extra sweetness. You could also mix in banana slices. The banana adds a nice twist to the flavor. If you want something nutty, try almond butter instead of peanut butter. The options are endless!
Dietary Adjustments
Want to make it gluten-free? Use almond flour or oat flour. Both work great in this recipe. For a dairy-free version, choose almond milk or coconut milk. These swaps keep the cake soft and moist. You can still enjoy all the flavors without the dairy or gluten.
Serving Sizes and Multiplication
If you want to share, it’s easy to make more. Just double or triple the ingredients. Use larger mugs for bigger portions. Remember to adjust the cooking time. A larger mug cake may need a bit more time in the microwave. Check it often to avoid overcooking. Enjoy with friends or save some for later!
Storage Info
Best Practices for Storing
You might not have leftovers, but if you do, cover the mug cake with plastic wrap. This keeps it from drying out. You can also place it in an airtight container. Store it in the fridge for best results. To reheat, pop it in the microwave for about 15 to 30 seconds. Check until it feels warm but not hot. This helps keep the texture soft and moist.
Shelf Life Recommendations
The mug cake stays fresh for about 2 days in the fridge. After that, it may lose its fluffiness and taste. If you see any signs of mold or strange smells, throw it away. Enjoy your quick treat while it’s at its best!
FAQs
Can I use a different type of flour?
Yes, you can use other flours. Almond flour or oat flour work well. Just remember that they may change the texture. If you choose gluten-free flour, the mug cake will taste different.
How long does it take to cook in a different microwave?
Cooking time can vary by microwave. Start with 1 minute and 30 seconds. Check the cake for doneness after that time. If it’s not set, add 10-second intervals. Keep an eye on it to avoid overflow.
Can I make this mug cake egg-free?
Yes, this mug cake is already egg-free! The peanut butter and milk give it enough moisture and richness. You won’t miss the eggs at all.
