Ingredients
To create this delicious Peanut Butter Mug Cake, gather the following ingredients:
- 1 ½ Tablespoons Vegetable Oil
- 2 ½ Tablespoons Brown Sugar
- 1 Egg White (from a large egg)
- 2 ½ Tablespoons Creamy Peanut Butter
- 3 Tablespoons All-Purpose Flour
- 1/4 teaspoon Baking Powder
- 1 Tablespoon Chocolate Chips
Having these ingredients on hand will make your mug cake adventure a breeze!
Mixing the Base

Now, let’s get into the fun part! Grab a microwave-safe mug and combine the vegetable oil, brown sugar, and egg white. Use a fork to whisk these ingredients together until you’ve achieved a uniform mixture. This step is crucial for getting a smooth base for your cake. Make sure everything is well blended; you want no granules of sugar left at this point.
Incorporating the Peanut Butter
Next up, it’s time to add that creamy peanut butter! Scoop it into the mug and stir vigorously. This will not only blend the peanut butter completely into the mixture but also infuse your cake with that deliciously nutty flavor we all crave. Ensure there are no lumps; they could result in uneven baking.
Adding the Dry Ingredients
Once your base is ready, sprinkle the all-purpose flour, baking powder, and chocolate chips into the mug. Gently mix everything together until all the components are just combined. A good rule of thumb here is to avoid overmixing, as that can affect the cake’s texture. You should see a nice, thick batter that’s ready for the microwave.
Cooking the Mug Cake
Now, it’s time for the magic to happen! Place your filled mug in the microwave and cook it on high for 1 minute and 10 seconds. Keep an eye on it while it cooks, as microwave wattage can vary. You want to make sure it’s cooked through but not overdone; otherwise, it may dry out. The top should look set and slightly domed.
Serving Suggestions
Once your Peanut Butter Mug Cake is done, you have a couple of choices for how to enjoy it. You could dive right in with a spoon straight from the mug, savoring every bite. However, if you feel a bit fancy, you could turn it out onto a plate and add some toppings. Consider a dollop of whipped cream, a scoop of vanilla ice cream, or even a drizzle of chocolate syrup for an extra special treat. The possibilities are endless!
Tips for Success
- Ensure your mug is large enough to prevent spills while the cake rises. A bigger mug gives the cake room to puff up beautifully.
- Use a fork instead of a whisk for easier mixing; it helps incorporate everything without making a mess.
- Allow the cake to cool slightly before diving in as it retains heat. You don’t want to burn your tongue on this delicious treat!
Variations
Feeling adventurous? Here are a few fun variations you can try:
- Nutty Additions: Mix in chopped nuts like walnuts or pecans for added texture.
- Flavor Twist: Swap peanut butter with almond butter or add a sprinkle of cinnamon to give it a different taste.
- Vegan Option: Substitute the egg white with an equivalent amount of applesauce or a flax egg.
These variations can make your mug cake experience even more enjoyable and customized!
Storage Tips
This peanut butter mug cake is best enjoyed fresh. If you happen to have leftovers, store them in an airtight container in the fridge for up to 1 day. To restore warmth, simply reheat in the microwave for a few seconds before enjoying.
Pairing Ideas
To complement the sweetness of this mug cake, consider pairing it with a hot coffee or a glass of cold milk. The creamy flavors balance out perfectly! For an added treat, fresh strawberries or raspberries alongside your cake create a wonderful contrast of flavors.

FAQs
Q1: Can I make this mug cake without an egg?
A1: Yes! Substitute the egg white with 2 tablespoons of applesauce or 1 tablespoon of flaxseed mixed with 3 tablespoons of water.
Q2: How can I make this recipe gluten-free?
A2: Use a gluten-free all-purpose flour blend instead of regular flour.
Q3: Can I double the recipe?
A3: It’s best to make separate mug cakes, as doubling the ingredients can lead to uneven cooking.

A4: For the best flavor and texture, enjoy it immediately. If stored, consume within 1 day.
