Step-by-Step Instructions
Preparation of Dry Ingredients
First, grab a microwave-safe mug. In the mug, add 4 tablespoons of all-purpose flour. Next, toss in 3 tablespoons of granulated sugar. Then, add 2 tablespoons of unsweetened cocoa powder. Don’t forget 1/4 teaspoon of baking powder and a pinch of salt. Mix these dry ingredients well. This step is key for a smooth mug cake.
Combining Wet Ingredients
Now, it’s time for the wet mix. Pour in 1/4 cup of milk. You can use dairy-free milk if you want. Next, add 2 tablespoons of creamy peanut butter. Finally, include 1/2 teaspoon of vanilla extract. Stir all these together until you get a smooth batter. Make sure there are no lumps in your mix.
Cooking the Mug Cake
Once your batter is ready, gently fold in 2 tablespoons of chocolate chips. This adds rich flavor. Now, place the mug in the microwave. Cook it for about 1 minute and 30 seconds. Keep an eye on the mug cake. Microwaves can vary, so check if it has risen and looks set. After cooking, let it cool for a minute. Enjoy your mug cake straight from the mug!
Tips & Tricks
How to Avoid Overcooking
To keep your mug cake soft, watch the time closely. Start with one minute and thirty seconds. Every microwave works a bit differently. If it looks set but still jiggles slightly, it’s done. Letting it cool for a minute will help, too. This way, you can enjoy a moist cake.
Enhancing Flavor with Toppings
Toppings can really elevate your mug cake. You can sprinkle extra chocolate chips on top for sweetness. A dollop of whipped cream adds creaminess. Try drizzling warm peanut butter or chocolate sauce over it. Fresh fruit like bananas or strawberries also works well. These toppings make your cake even more fun to eat.
Storing Leftovers or Unused Batter
If you have leftover mug cake, store it in an airtight container. Keep it in the fridge for up to two days. Reheat it in the microwave for about ten seconds before enjoying again. If you have unused batter, you can store it in the fridge too. Just make sure to cover it well. Use it within a day for the best taste.
Pro Tips
- Adjust Cooking Time: Depending on your microwave's wattage, you may need to adjust the cooking time. Start with 1 minute and increase in 10-second increments if needed. Keep an eye on it to prevent overcooking.
- Experiment with Nut Butters: While peanut butter is delicious, try substituting with almond or cashew butter for a different flavor profile. Each nut butter offers a unique taste and texture!
- Mix-Ins Galore: Don’t hesitate to add other mix-ins like chopped nuts, dried fruit, or even a dollop of Nutella for an extra treat. Get creative with your flavors!
- Perfect Serving Size: This recipe is designed for one, but you can easily double or triple the ingredients to make multiple mug cakes. Just ensure you use larger mugs and adjust the cooking time accordingly.
Variations
Gluten-Free Options
You can make this mug cake gluten-free. Simply swap all-purpose flour for a gluten-free blend. Look for blends that contain rice flour, tapioca, and potato starch. These work well for baking. Using a gluten-free flour blend keeps the texture light and fluffy.
Nut-Free Substitute Ideas
If you need a nut-free version, use sun butter or soy nut butter. These spreads mimic peanut butter's creaminess. They add a nice flavor without using nuts. Just ensure your chocolate chips are also nut-free.
Flavor Additions
You can get creative with flavors! Add sprinkles for fun, or mix in chopped nuts. Try using white chocolate chips for a different taste. You can even add a dash of cinnamon for warmth. A dollop of whipped cream on top makes it extra special. Enjoy your mug cake with these tasty twists!

Reheating Instructions

FAQs
How do I know when my mug cake is done?
You can tell your mug cake is done when it has risen and looks set. It should not jiggle in the middle. You can also insert a toothpick into the center. If it comes out clean, your cake is ready. Microwave times vary, so check it after one minute. If it needs more time, add ten-second intervals until done.
Can I use different types of nut butter?
Yes, you can use different nut butters in this recipe. Almond butter, cashew butter, or sunflower seed butter work well too. Just keep in mind that the flavor will change a bit. Each nut butter has its own taste, which will add a unique twist to your cake.
What can I do if I don't have a microwave?
If you don’t have a microwave, you can bake the mug cake in a small oven. Preheat your oven to 350°F (175°C). Pour the batter into an oven-safe mug or ramekin. Bake for about 15 to 20 minutes. Keep an eye on it, and check for doneness with a toothpick.
