Peanut Butter Mug Cake Recipe Substitutions And Additions
PEANUT BUTTER: You can substitute crunchy or chunky peanut butter for the creamy in a one-to-one ratio for this mug cake.
SUGAR: Try using brown sugar for a richer, more caramel like taste in your mug cake.
FLOUR: You can substitute four tablespoons of all-purpose flour and a quarter teaspoon of baking powder for the self-rising flour.
BUTTER: You can substitute an equal amount of vegetable oil for melted butter in this simple cake.
CHOCOLATE: Either mixed in or added on top, a tablespoon of chocolate chips or peanut butter chips make this mug cake recipe even more yummy.
COCOA POWDER: Add one to two tablespoons of cocoa powder to make this a chocolate peanut butter mug cake.
TOPPINGS: There are plenty of ways to customize your tasty cake. Add whipped cream, a drizzle of hot fudge sauce, and a maraschino cherry on top of the cake.
MILK: Whether you’re lactose intolerant or prefer non-dairy milk, you can easily swap out regular milk for almond milk, soy milk, coconut milk, or oat milk in equal amounts.
These alternatives will give your cake a slightly different flavor profile, making it suitable for various dietary preferences.
VANILLA EXTRACT: Experiment with different extracts to change the flavor. Try almond extract for a nuttier twist or coconut extract for a tropical touch.
Just remember that almond and coconut extract are potent, so start with a smaller quantity and adjust to taste.
SPICES: Experiment with different spices to elevate the taste. A pinch of nutmeg or a dash of cinnamon can bring warm, aromatic notes to your peanut butter cake.
How To Make This Peanut Butter Cake In A Mug Recipe
This is one of the easiest ways to make a cake! You only need a mug to mix up and enjoy this treat.
Our step-by-step instructions below will walk you through the basic steps of making your mug cake.
OUR RECIPE DEVELOPER SAYS
If you are serving more than one person, you can assemble all your ingredients in each mug and then microwave them one at a time.
TO BEGIN: You may wish to spray the inside of your mug with nonstick cooking spray to make clean up a snap.
STEP ONE: Add the flour and granulated sugar to a 14-ounce microwave-safe mug. Stir to combine.
PRO TIP:
Using a wider and shorter cup works best and makes it easier to scoop out your cake.
![flour and sugar combined in a mug](https://spaceshipsandlaserbeams.com/wp-content/uploads/2022/10/Peanut-Butter-Cake-in-a-Mug-Step1.jpg)
STEP TWO: Add the peanut butter, milk, melted butter, and vanilla. Stir to incorporate completely.
![peanut butter, milk, melted butter, and vanilla stirred in a mug](https://spaceshipsandlaserbeams.com/wp-content/uploads/2022/10/Peanut-Butter-Cake-in-a-Mug-Step2.jpg)
STEP THREE: Microwave cake for 1 minute 30 seconds to 1 minute 45 seconds.
The cook time needed for this sweet treat can vary with different microwaves.
PRO TIP:
Keep a close eye on the cake while it’s in the microwave and cook it until the center is just set.
![place mug in the microwave](https://spaceshipsandlaserbeams.com/wp-content/uploads/2022/10/Peanut-Butter-Cake-in-a-Mug-Step3.jpg)
STEP FOUR: Allow the cake to cool for a few minutes before serving. While the cake is cooling, you can add an extra drizzle of peanut butter on top of the cake.
The heat from the cake will melt the peanut butter. You can gently spread the peanut butter over the top of the cake to completely cover the surface if you wish.

Troubleshooting Tips for Peanut Butter Cake in a Mug
The consistency of my batter is wrong.
Solution: If the batter is too thick, add a little more milk to achieve a smooth consistency. If the batter is too thin, add a little more flour.
My mug cake isn’t cooking properly.
Solution: Cooking times can vary with different microwaves. Start with the lower time range and add more time in 15-second increments if needed.
How do I know if my mug cake is done and ready to eat?
Solution: Check if the cake is done by inserting a toothpick in the center. If it comes out clean, it’s ready.
How To Serve This Mug Peanut Butter Cake
It’s perfectly fine to enjoy this peanut butter treat on its own, but you could also turn it into an even more indulgent dessert.
SERVE WITH ICE CREAM: Add a scoop of vanilla ice cream and whipped cream to satisfy your sweet tooth.
WITH FROSTING: To make this amazing mug cake even better, serve with homemade chocolate whipped cream, Cool Whip frosting, cream cheese frosting, or Mascarpone frosting.
ADD TOPPINGS: For added decadence, drizzle one of these sauces on top:
SERVE WITH A COLD DRINK: A refreshing glass of iced tea, strawberry lemonade, or Orange Julius is perfect to wash your individual cake down.
