Step-by-Step Instructions
Preparing the Dry Ingredients
Start with a microwave-safe mug. This is key for cooking. Add 4 tablespoons of all-purpose flour to the mug. Next, mix in 2 tablespoons of sugar. Then, add 1/2 teaspoon of baking powder and 1/8 teaspoon of salt. Stir these dry ingredients together well. This step is simple but very important for even baking.
Mixing Wet Ingredients and Combining
Now, it’s time for the wet ingredients. Pour in 3 tablespoons of milk. You can use dairy or non-dairy milk. Next, add 2 tablespoons of peanut butter. This gives the cake its rich flavor. Then, pour in 1 tablespoon of vegetable oil. Finally, add 1/4 teaspoon of vanilla extract. Use a fork to whisk everything together. Make sure it is smooth and free of lumps. If you want, you can fold in some chocolate chips or crushed peanuts for extra fun.
Cooking in the Microwave
Place the mug in the microwave. Cook it on high for 30 to 40 seconds. Watch closely as it cooks. The cake should rise and look set in the middle. Be careful not to overcook it, or it may get tough. Once done, let the mug cake cool for about one minute. Then, enjoy it right from the mug. You can add more peanut butter or a sprinkle of powdered sugar on top. This treat is quick, easy, and oh so tasty!
Tips & Tricks
How to Achieve the Perfect Texture
To get the best texture for your mug cake, follow these tips:
– Use a microwave-safe mug. Choose one that holds at least 12 ounces.
– Mix your dry ingredients well before adding wet ones. This helps avoid lumps.
– Stir the batter until smooth, but don’t over-mix. A few lumps are okay.
– Microwave in short bursts. Start with 30 seconds, then check it. If needed, add 10 seconds.
– Let it sit for a minute after cooking. This lets the cake firm up a bit.
Common Mistakes to Avoid
Here are some common mistakes people make:
– Using too much flour. Measure carefully to keep your cake from being dry.
– Not mixing well enough. This can lead to a lumpy texture.
– Cooking for too long. Keep an eye on it to prevent a rubbery cake.

Variations
Alternative Nut Butters
You can switch out peanut butter for other nut butters. Almond butter offers a nice twist. Cashew butter brings a creamy richness. Sunflower seed butter is great for nut-free diets. Each nut butter adds its own flavor. You can try different types until you find your favorite.
Vegan and Gluten-Free Options
To make this mug cake vegan, use almond milk or oat milk instead of dairy. Replace the sugar with maple syrup or coconut sugar. For gluten-free options, swap all-purpose flour with a gluten-free flour blend. This way, everyone can enjoy it, regardless of their diet.
Creative Flavor Combinations
Get creative with flavors! Add cocoa powder for a chocolatey treat. Mix in cinnamon for spice. You can also stir in vanilla extract or a splash of almond extract for extra flavor. Experiment with toppings too! Try using sliced bananas, berries, or even a dollop of yogurt. Each choice can change your mug cake experience.
Storage Info
Best Practices for Storing Mug Cakes
To keep your mug cake fresh, store it in an airtight container. This prevents moisture from getting in. If you made it with toppings, cover them lightly to keep them crisp. Always let the cake cool before sealing the container. This helps avoid sogginess.
Can You Reheat Mug Cakes?
Yes, you can reheat your mug cake. Place it back in the microwave for about 10-15 seconds. Check it often to avoid overcooking. If it seems dry, add a splash of milk to bring back moisture.
Shelf Life and Signs of Spoilage
Your peanut butter mug cake can last up to two days at room temperature. If you store it in the fridge, it can last up to a week. Look for signs of spoilage like a dry texture or an off smell. If it looks or smells bad, it’s best to throw it away.
