A guest at my show last night asked how long to bake brownies in this stone. I haven't ever done it and knew this lady well enough to know that "Just keep an eye on it the first time to get a feel for how long" wasn't going to be an acceptable answer, so I guessed twenty-five, thirty minutes? I am going to test it myself but thought I would throw out the question here in case somebody knows from personal experience.
25-28 minutes There's a recipe for Truffle Brownies in Stoneware Inspirations that calls for baking the brownies 25-28 minutes at 325 degrees in the medium bar pan, so I think you made a great guess! HTH, Diane P.S. The recipe is AWESOME
I bake my brownies in my medium bar pan all the time. I bake them at 350* for 28 minutes. I have an electric stove and I believe every stove is different. I always recommend to guests, if recipe says bake for 25-28 minutes, to bake them for 28 minutes and test with toothpick or cake tester to see if its really done!
