The one I made was 4 Tbsp flour, 4 Tbsp sugar, 2 Tbsp unsweetened cocoa. Pinch of salt, dash of vanilla. 2 Tbsp water, 2 Tbsp vegetable oil. Give it a good stir and micro for one minute.
My husband didn't think we had all the ingredients, and I was like "um, hello? I'm a baker now, remember? OF COURSE we have the ingredients!"
