Kitchen Utensils

- Microwave

Ingredients
- 2 tbsp peanut butter (made from roasted peanuts)
- 1 tbsp cocoa powder (made from cocoa beans)
- 2 tbsp powdered sugar (cane sugar + cornstarch)
- 1 tbsp whole milk powder
- 1 tbsp peanut flour
- 1 tbsp cane sugar
- A pinch of sea salt
- 1 tbsp cocoa butter (melted)
Instructions
1. In a microwave-safe mug, mix together the powdered sugar, cocoa powder, whole milk powder, peanut flour, cane sugar, and a pinch of sea salt until evenly blended.
2. Add the peanut butter and melted cocoa butter to the dry mix. Stir thoroughly until you get a smooth, thick batter. You can microwave the cocoa butter slightly beforehand to melt it if needed.
3. Stir everything well to incorporate all the ingredients into a consistent batter. It should be thick but smooth.
4. Place the mug in the microwave and cook on high for about 60 seconds. Cooking times may vary depending on your microwave, so check at 45 seconds and then adjust as needed. The cake should rise and be firm to the touch but moist inside.
5. Let the mug cake cool for a minute or two before eating it will be hot! Enjoy directly from the mug.
Notes
❖ Microwave Wattage: The cooking time may vary depending on the wattage of your microwave. If your cake isn’t fully set after 1 minute, you can microwave it in 10-15 second intervals, checking each time. Make sure not to overcook it, as it can become dry.
❖ Mug Size Matters: Be sure to use a mug that’s large enough (12-16 oz) to avoid overflowing. The cake will rise while cooking, and if the mug is too small, it may spill over.
❖ Allow It to Cool Slightly: The cake will be very hot right after microwaving, so give it a minute to cool down before digging in. It also allows the flavors to settle and improves the texture!
My Favorite Ways To Serve It Up
Serve your Chocolate Peanut Butter Mug Cake Recipe warm with a scoop of vanilla ice cream or a dollop of whipped cream to add creaminess.
Drizzle honey or maple syrup on top for a touch of sweetness. For extra texture and flavor, sprinkle crushed roasted peanuts or chocolate chips.
Fresh fruit like strawberries or bananas adds a refreshing contrast, while a small pinch of sea salt flakes enhances the rich peanut butter and chocolate taste. Simple, delicious, and perfect every time!
Tips And Variations
Tips:
- Microwave time may vary: Depending on your microwave’s power, you may need to adjust the cooking time by a few seconds. Keep an eye on the cake to prevent overcooking.
- Customize the sweetness: If you like your desserts sweeter, you can increase the sugar by a teaspoon.
- Use almond butter or other nut butters: If you’re not a fan of peanut butter, almond butter or cashew butter can be a great alternative.
- Add more texture: Add chocolate chips, chopped nuts, or even marshmallows for extra texture and flavor.
Variations:
- Vegan version: Use a non-dairy milk (like almond or oat milk) and replace the butter with coconut oil. Also, opt for a plant-based peanut butter.
- Gluten-free option: Swap the all-purpose flour with a gluten-free flour blend. Make sure to check your baking powder is gluten-free too.
Storage & Make Ahead
This Chocolate Peanut Butter Mug Cake Recipe tastes best fresh for optimal texture and flavor. The batter can be prepared ahead and stored in an airtight container in the fridge for up to 24 hours.
Before microwaving, stir the batter briefly to mix. Cooked mug cake leftovers can be covered and refrigerated for up to 2 days.
Warm the Chocolate Peanut Butter Mug Cake Recipe in the microwave for 20–30 seconds to enjoy it warm again.
FAQs
Can I make this mug cake without peanut butter?
Yes, you can replace the peanut butter with other nut butters like almond or cashew butter, or even use sunflower seed butter if you’re allergic to peanuts.
Can I make this mug cake gluten-free?
Absolutely! Simply swap the all-purpose flour with a gluten-free flour blend. Just make sure the baking powder you use is also gluten-free.
How do I adjust the sweetness of the cake?
If you prefer a sweeter mug cake, you can increase the sugar by a teaspoon or try adding a bit of honey or maple syrup for a different sweetness profile.
Can I double the recipe to make two servings?
While you can double the ingredients, I recommend making two separate mugs instead of doubling everything in one mug. This ensures the cake cooks evenly.
How long should I microwave the mug cake if my microwave is lower wattage?
If your microwave has lower wattage, try microwaving the mug cake in 10-15 second intervals, checking after each interval until the cake is set and a toothpick comes out clean. It might take 1.5–2 minutes.
