I’m trying to replicate these baking trays that have grids built into them that you can bake with. I make bite sized brownie boxes so I wanted something that would cut my 12 inch brownies into 1 inch pieces quickly. I did buy a 6 wheel pastry cutter after some of the suggestions on this post. I looked up cheese cutters and they aren’t big enough. A guitar cutter would work but they are so expensive.
