Just mix and microwave! Kids can make these because there's no need to cook anything over heat. They are cute and colorful!
I was looking for a recipe for microwaved cookies that even kids could make, and I tried this! I often used to make pancake mix this way too.
The cookies will bake from the inside, so even if the surface isn't baked, they might still be done. Check on them and adjust the time between 3 - 3.5 minutes as necessary.
Enjoy Japanese food around the world.
