It’s hard to know when to take things out of the oven, at least for me. I’m constantly peeking into the oven and thinking to myself “maybe just a few more minutes…” Often our fear of under baking trumps our concern of over baking and we bake things a little longer than we should.
Sometimes it’s not really noticeable, other times it is. If you bake these gooey cinnamon squares for too long, you lose the gooey layer and the best thing about them. Take these out of the oven when the cinnamon sugar is crisp, the edges have browned, but the gooey layer is still very gooey and seemingly under baked. It will firm up when it cools, I promise.
