Common questions about microwave brownies

What type of chocolate can I use? You need unsweetened cocoa for this recipe which is a type of dark chocolate. It ’ randomness besides called acerb chocolate, cooking chocolate or baking cocoa. Can I use cocoa instead of unsweetened chocolate? Yes. Use 1/2 cup unsweetened cocoa. Can I replace the butter with oil? Yes. Use 1/2 cup oil ( or 1/3 if you want a cakier brownie ) Is it OK if my brownies are slightly wet in the middle when they come out of the microwave? Yes, flimsy under baking is good for fudgier brownies arsenic long as they are not crude. The brownies will finishing setting while they cool. If you prefer cakier brownies, add a few more seconds at a time ( say, a total of 10-30 seconds ) until a examiner comes out dry. Will the microwave cook time be different if my microwave power/wattage is lower? Yes. These brownies used to take me 6 minutes in my old 600 watt microwave back in the day. See respective watts and times in the recipe notes. What makes a brownie fudgy or cakey? Fudginess and chewiness in a elf comes from the fat ( butter and chocolate ) a well as under baking. Brownies will get more chewy the future day. If you prefer a cakier brownie, I suggest reducing the butter fair a little, skipping the chocolate chips and adding a few more seconds in the microwave.
