Ingredients
Main Ingredients
– 4 tablespoons all-purpose flour
– 1 tablespoon unsweetened cocoa powder
– 1/4 teaspoon baking powder
– 2 tablespoons creamy peanut butter
– 3 tablespoons milk (dairy or plant-based)
These main ingredients form the base of the mug cake. The all-purpose flour gives it structure, while cocoa powder adds the rich chocolate flavor. Baking powder helps the cake rise. Creamy peanut butter brings a nutty taste, and milk adds moisture.
Sweeteners and Flavorings
– 2 tablespoons brown sugar (or substitute with maple syrup)
– 1/2 teaspoon pure vanilla extract
– 1 tablespoon semi-sweet chocolate chips
– A pinch of salt
Sweeteners like brown sugar or maple syrup make the cake sweet. Vanilla extract adds depth of flavor. Semi-sweet chocolate chips give bursts of chocolate. A pinch of salt balances the sweetness, enhancing all the flavors. This mix of flavors makes each bite special.

Step-by-Step Instructions
Prepping the Mug
Start by choosing a microwave-safe mug. Look for one that holds about 12 ounces. This size works best for our cake. Next, combine the dry ingredients. In your mug, mix these items:
– 4 tablespoons all-purpose flour
– 1 tablespoon unsweetened cocoa powder
– 1/4 teaspoon baking powder
– A pinch of salt
Use a fork or a small whisk to blend them well. Make sure there are no lumps. A smooth mix helps the cake rise evenly.
Mixing the Batter
Now, it’s time to add the wet ingredients. Pour in:
– 2 tablespoons creamy peanut butter
– 3 tablespoons milk (you can use dairy or plant-based)
– 2 tablespoons brown sugar (or substitute with maple syrup)
– 1/2 teaspoon pure vanilla extract
Stir vigorously with your fork or whisk. Keep mixing until you see a smooth batter. No dry flour should be visible. This step is key for a great texture.
Then, fold in the chocolate chips gently. Use one tablespoon of semi-sweet chocolate chips. Distribute them evenly throughout the batter.
Cooking the Cake
Place your mug in the microwave. Cook on high for about 1 minute and 30 seconds. Watch closely to avoid overflow. The cake will rise as it cooks.
Check for doneness by touching the center. It should feel firm. If it’s too soft, cook for a few more seconds.
Once done, let it cool for about 1 minute. Now, you can enjoy your mug cake straight from the mug!
Tips & Tricks
Customizing Your Cake
You can easily change this recipe to fit your taste. Here are some ideas:
– Ingredient substitutions: If you want to use whole wheat flour, that works too. You can also swap the creamy peanut butter for crunchy if you like texture. For a nut-free version, try sunflower seed butter instead.
– Adjusting sweetness levels: If you prefer a less sweet cake, cut back on the brown sugar. You can also use a sugar substitute like stevia to lower calories.
Cooking Precautions
Cooking a mug cake is quick but needs care. Here are some tips:
– Preventing overflow during microwaving: Use a mug that’s at least 12 oz. This gives the cake room to rise. Keep an eye on it while it cooks. If you see it rising too much, pause the microwave for a few seconds.
– Cooling time before serving: Let the cake cool for about 1 minute. This helps avoid burns and makes it easier to eat.
Presentation Ideas
Make your mug cake look as good as it tastes. Here are some fun ideas:
– Toppings and accompaniments: Add a sprinkle of extra chocolate chips on top. A drizzle of peanut butter can make it even better. You could also add a dollop of whipped cream or yogurt for creaminess.
– Serving suggestions for an enhanced dessert experience: Serve your mug cake with a scoop of vanilla ice cream. The warm cake paired with cold ice cream is a great contrast. Enjoy it with friends or family to share the joy!
Pro Tips
- Microwave Variations: Microwave power levels can vary, so adjust the cooking time as needed. Start with 1 minute and add 10-second intervals until fully cooked.
- Flavor Enhancements: Experiment with different nut butters, like almond or cashew, for a unique flavor twist on your mug cake.
- Mix-Ins Galore: Add chopped nuts, dried fruit, or a sprinkle of sea salt to enhance the flavor and texture of your mug cake.
- Storage Tips: If you have leftovers (though unlikely!), cover your mug cake with plastic wrap and refrigerate for up to a day. Warm it slightly in the microwave before enjoying again.
Variations
Flavor Combinations
You can easily change the taste of your mug cake. Add chopped nuts, like walnuts or almonds, for a crunchy texture. They add a nice contrast to the soft cake. You can also try using different types of chocolate. Dark chocolate chips give a richer flavor, while white chocolate adds sweetness.
You can switch up the nut butter too. Almond butter or cashew butter can bring new flavors to your cake. Each nut butter has its unique taste and texture. This way, you can make a new mug cake each time!
Dietary Alternatives
If you want a gluten-free mug cake, you can use gluten-free flour instead of all-purpose flour. Look for blends that work well in baking. They create a similar texture and taste.
For a vegan version, swap the milk for plant-based milk like almond or oat milk. Use a flax egg instead of regular eggs. Just mix one tablespoon of ground flaxseed with two and a half tablespoons of water. Let it sit for a few minutes to thicken. These changes keep the cake soft and delicious!
Storage Info
Enjoying Fresh vs. Make-Ahead
I love eating this mug cake right after it cooks. It tastes best warm. If you have leftovers, let the mug cake cool first. Then, cover it with plastic wrap or a lid. Store it in the fridge for up to two days.
When you want to enjoy it again, take it out and let it sit at room temperature for a few minutes. This helps bring back some of that warm, fresh taste.
Reheating Instructions
To reheat the mug cake, place it back in the microwave. Heat it for 15 to 20 seconds. Check if it’s warm enough. If not, heat it in small bursts. This keeps the texture soft and fluffy. Too much heat can make it dry, so keep an eye on it!
FAQs
How do I make a Peanut Butter Chocolate Chip Mug Cake without a microwave?
You can bake your mug cake in an oven. Preheat your oven to 350°F (175°C). Use a small oven-safe dish instead of a mug. Mix the ingredients as stated in the recipe. Pour the batter into your dish and bake for about 15 minutes. Check the cake with a toothpick. It should come out clean. This method gives a nice texture. You can also use an air fryer. Set it to 350°F (175°C) and cook for about 10-12 minutes.
Can I make this mug cake ahead of time?
Yes, you can prepare the dry mix ahead. Combine flour, cocoa powder, baking powder, and salt in a bowl. Store this mix in an airtight container. When you want to make the cake, just add the wet ingredients. Mix, then cook. This way, you save time when you’re ready to enjoy your treat. It’s best to eat the mug cake fresh. If you store leftovers, keep them in the fridge for up to one day.
What should I do if my mug cake overflows in the microwave?
To prevent overflow, use a bigger mug. A 12-ounce mug can be tight, so choose a larger one. Fill the mug only halfway with batter. Keep an eye on it while cooking. If it starts to rise too much, stop the microwave for a few seconds. Open the door and let it settle. Restart cooking after. This way, you avoid a mess and keep your microwave clean.
