I know you want to cut into it immediately. That smell of cinnamon and butter is practically a primal call. But please wait at least 20 to 30 minutes after taking it out of the oven.
Why? Because the filling needs to set. If you slice it hot, you’ll end up with a soupy mess that slides off your plate. Give it time to find its inner strength. Use those 20 minutes to brew some coffee or scoop some ice cream.
