👨🍳 How To Make
Follow this easy recipe:
Step 1
Add all the ingredients to a large bowl.
Step 2
Mix well until well combined.
Step 3
Fill a mug with the batter – make sure to leave plenty of room because this cake expands a lot.
Step 4
Microwave on high for about 2 minutes. The best way to test if it’s ready is to insert a toothpick in the center and see if it comes out dry.
Step 5
Make the topping by melting the white chocolate chips in the microwave in a small bowl. Spread over the mug cake and enjoy!

💡Tips
1. Room in Your Mug
This is probably the most important tip for getting your mug cake right. The batter will expand a lot during cooking – sometimes it can double in size or even more. If you fill your mug too full, the cake will overflow all over your microwave, creating a big mess.
Use a large coffee mug or even a small bowl if that’s what you have. Fill it only about halfway with batter, even though it might look like there’s not enough.
Trust me, there will be plenty once it starts cooking. The cake needs space to rise and get fluffy.

2. Melt Your Coconut Oil Completely
Coconut oil is solid at room temperature, so you need to melt it before adding it to your batter.
If you add solid coconut oil, it will create lumps that don’t mix in properly. The easiest way to melt it is to put it in a small bowl and microwave it for about 10 seconds, just until it becomes liquid.
3. Let It Cool Before Adding Toppings
When your mug cake comes out of the microwave, it will be very hot, especially in the center.
If you try to add the melted white chocolate topping right away, it will just melt and run right off the cake instead of staying on top where you want it. Let the cake cool for at least 2-3 minutes before adding any toppings.

FAQ
Can I use a different sweetener instead of erythritol?

You can substitute erythritol with other keto-friendly sweeteners, but you’ll need to adjust the amounts because they have different sweetness levels.
