Creamy, fluffy, eggless peanut butter cake mixed with melty chocolate chips. This single serving mug cake is ready in about 5 minutes.
It’s been a while since I made a mug cake. But it’s really perfect right now. Because even though I’m trying to eat healthy, I still need a little treat. And this single serving cake means I won’t be tempted to eat an entire full-sized cake or a dozen cookies.
The peanut butter mug cake is one of my favorites. I just adjusted my recipe a little to add melty chocolate. I used chocolate chunks rather than standard chocolate chips since the chunks are bigger. I’m so happy Nestle came out with chocolate chunks so I don’t have to buy them at specialty baking stores.
This cake is best eaten warm, while the chocolate is still melty and gooey. Because this cake is eggless, the crumb is a little loose. It’s best eaten in the mug as it won’t hold up well if you try to remove it from the mug. So I recommend you just grab a spoon and dig in.
Here is a video of the recipe too! You can also follow my YouTube page for all the latest recipe videos.
Peanut Butter Chocolate Chip Mug Cake
Ingredients
- 4 tbsp all-purpose flour
- 1/4 tsp baking powder
- 1 tbsp granulated sugar
- 1/4 cup fat-free milk
- 3 tbsp creamy peanut butter
- 3 tbsp semi-sweet chocolate chunks or chocolate chips
Instructions
- In a microwave safe mug, add all ingredients except chocolate. Using a small whisk, mix vigorously until batter is smooth and no flour chunks remain.
- Stir 1 tbsp of chocolate chips into the cake batter. Add another 1 tbsp concentrated in the center/middle of the batter (so that when you dig into the center of your cake when it's finished, it has a concentrated amount of chocolate). Sprinkle remaining 1 tbsp on top.
- Cook in the microwave at full power for about 1 minute. If cake batter is still gooey, cook for an additional 15 seconds. Allow cake to cool a few minutes before eating. Cake is best eaten warm.
Notes
- It is best to eat the cake directly from the mug and avoid removing it from the mug to eat it as the crumb is looser than a traditional cake.
- If you choose to omit the chocolate chips, you may need to add more sugar to the batter.

Yummy ?
I’m glad you liked it
This was the perfect dessert for a single serving. It was super easy to make, moist, and full of peanut butter flavor. Definitely a keeper!
So glad you enjoyed!
Delicious with oat milk
Thanks for sharing that suggestion!
It’s a little bitter for my liking and it sorta loses its flavor so I would recommend vanilla and milk chocolate chips.
Thanks for your suggestions!
i use this recipe consistently, but sub 1 tbsp of flour for a vanilla protein powder and occasionally use rolled oats instead of flour to make a heartier breakfast option. as written, or with modifications, it turns out delicious!
Thanks for sharing your adjustments! So glad you enjoy the recipe.
Yay!!! Okay, I haven’t tried this…but I was so against mug cakes because mine always ended up overcooked, eggy tasting, and rubbery. Then, I found a delicious chocolate mug cake recipe on TableforTwo, and I am so excited that this is eggless too! I actually came across your page looking at matcha stuff, but I’m excited to add this to my arsenal of recipes. I know it will be amazing! Like TableforTwo said, why put a whole egg in a small serving of cake when you use like 1-2 eggs for a whole cake. Truly, I’m glad people get it 🙂
I hope you try some of our mug cakes!
!!!! This is SO GOOD!!! I’m a total baking newb, but you gave great instructions and this is the first time I’ve made a mug cake with decent texture! This’ll be happening again! Thank you!
I’m so glad it worked out for you!
Your recipes are simple and awesome! I’m really bad at making desserts, but your recipes have given even someone like me the confidence. Keep the recipes coming. You are the best!!
thank you for the kind words!
Good consistency but not sweet enough. Little salt to bring out the flavor and maybe 2 tbsp of sugar instead of 1.
You can definitely add more sugar to suit your personal preference!
This is by far my favorite mug cake! It gives you a taste of a cookie as well as a cake in one. It gives you room to play around with ingredients and create a different version along with the original recipe! Thank you so much for this recipe ??
I’m so glad you like this recipe!
This worked great, I had low expectations since these mug cakes tend to work or not. I added some chunky peanut butter for texture, and it was delicious. Thank you for the recipe!
I’m so glad you liked it!
I had low expectations since I’ve never microwaved cake but this is amazing!
I’m so glad you liked it!
Absolutely delicious! The last time I made it, I substituted one of the tablespoons of flour with whole wheat flour & added a splash of vanilla and a pinch of fine sea salt, and it was wonderful! My go-to mug cake recipe now 🙂
Thank you for sharing! I’m so glad you like it!
I used white chocolate chips instead and it was delicious. This is a great recipe!
glad it worked out well for you!
can i use something instead of egg??
there is no egg…
I am a vegetarian person – if I want to make your receipes without egg which ingredients I can use instead of egg ?
there is no egg in this recipe
Can I make this without the baking powder? Is there a substitution
It needs baking powder to rise. I recommend checking out one of my flourless peanut butter mug cakes if you don’t have baking powder. https://kirbiecravings.com/3-ingredient-flourless-peanut-butter-cake-2/
It was one of those nights that my mom and I were beige watching cooking shows and felt our sweet teeth begin to kick in. I found this recipe and it was amazing, I did use milk with fat in it and it didn’t seem to effect it. If your just having a lazy kind of night and craving a delicious sweet, I highly suggest this recipe!
I’m glad you were able to satisfy your sweet tooth with this recipe!
Far superior to any mug cakes I’ve ever tried before! I’ve made it a dozen times and find it perfect for sweet cravings when I’m short on time. Today I used chopped Hershey bar in place of chips and it was delicious!
I’m so glad you enjoy this recipe so much!
This was the perfect recipe to curb my sweet tooth after dinner. Cake came out moist and perfectly cooked after 1 minute in the microwave. Loved it!
So glad you liked it!
