Key Ingredients
All-Purpose Flour (4 tablespoons)
The foundation of your mug cake, all-purpose flour provides the structure needed for a fluffy texture. It absorbs moisture and helps the cake rise, ensuring a satisfying bite every time.
Baking Powder (1/4 teaspoon)
A key leavening agent, baking powder helps the cake rise quickly in the microwave. It creates air pockets in the batter, resulting in a light and airy mug cake that’s not dense or heavy.
Brown Sugar (1 tablespoon)
Brown sugar adds sweetness along with a hint of molasses flavor, which perfectly complements the peanut butter. Its moisture content also helps keep the cake tender and soft.
Peanut Butter (1 tablespoon)
The star ingredient of this recipe, peanut butter infuses the cake with a rich, nutty flavor and creamy texture. It also adds protein, making this dessert a bit more filling.
Milk (3 tablespoons)
Milk hydrates the dry ingredients and contributes to the overall moisture of the cake. It also helps to create a tender crumb, making each bite enjoyable.
Vegetable Oil (1 tablespoon)
Adding vegetable oil keeps the cake moist and adds richness without compromising the flavor. It ensures that the cake doesn’t dry out during the cooking process.
Vanilla Extract (1/4 teaspoon)
A splash of vanilla extract enhances the overall flavor profile, adding a warm, aromatic element that pairs beautifully with the peanut butter.

Cooking Tips and Notes
Cooking a peanut butter mug cake is a straightforward process, but a few tips can enhance your experience. First, ensure your mug is large enough to allow the cake to rise without spilling over. A standard coffee mug usually works best.
Don’t Overcook
Microwave times can vary based on wattage, so start with 40 seconds and check for doneness. The cake should be set in the middle but still soft. Overcooking can lead to a dry texture, which no one wants in a dessert!
Customize Your Toppings
Feel free to get creative with toppings! While the mug cake is delicious on its own, adding a dollop of whipped cream, a drizzle of chocolate syrup, or a sprinkle of chopped nuts can take it to the next level. You can also adjust the sweetness by tailoring the sugar to your preference.
Storage Tips
This mug cake is best enjoyed fresh, as it can become dense if stored. However, if you have leftovers, cover the mug and refrigerate it. Just be sure to reheat it briefly in the microwave before enjoying it again.
With these tips, you can ensure that your peanut butter mug cake turns out perfectly delicious every time!
Serving Suggestions
Enjoying your peanut butter mug cake is just the beginning! This delightful dessert can be enhanced with various toppings and pairings that elevate its flavor and presentation.
Delicious Toppings
For a quick and easy upgrade, consider adding a dollop of whipped cream or a scoop of vanilla ice cream on top. The creaminess pairs perfectly with the rich peanut butter flavor, creating a heavenly combination. You can also drizzle some chocolate or caramel sauce for an extra touch of sweetness.
A Nutty Twist
For those who love a bit of crunch, sprinkle some chopped nuts, like peanuts or almonds, over the cake. This not only adds texture but also complements the nutty flavor of the peanut butter. A sprinkle of sea salt can also enhance the sweetness and provide a delightful contrast.
Serving with Fresh Fruits
Pairing your mug cake with fresh fruits like sliced bananas or strawberries adds a refreshing element. The natural sweetness of the fruits balances the richness of the cake, making for a well-rounded dessert experience.
