Fantastic pie! I made this for a neighborhood gathering, and there wasn't a crumb left over. Even the men gave it fantastic reviews! The toffee looks strange when it comes out of the oven (more like a custard consistency), but I stirred it, put it in the fridge, then completed the pie and it wasn't an issue. I used a 9" cheesecake mold/pan, and changed up the recipe slightly. Used 1 1/2 cans FAT-FREE sweetened condensed milk in the pie, (took the leftover and mixed it with coconut, chocolate chips and corn flakes for the kids ----yummy!), used 4 cups graham crackers with 4 TB Butter instead. It came out more like a pie than a tart, but was better for me because it actually served 20! Huge hit! Will definitely make it again!
