Why are my brownies hard around the edges and not set in the center?
We always recommend checking your oven temperature by baking a cake mix cake. If the cake is done within the timings on the package, your oven temperature is ok. If not, check your manufacturer's guide as to how to adjust your oven's temperature, or call a local appliance repair shop. If your oven temperature is ok, check to make sure you are using the correct pan called for in the recipe. Also make sure you measure your ingredients correctly.
