GRILLED CHEESE CAKE

Steps:

• Preheat the oven to 350 degrees F. Coat a 9-inch square, 2 1/4-inch-deep cake pan with cooking spray. Prepare the cake mix as directed; pour the batter into the pan. Bake 30 to 35 minutes. Cool slightly, then invert onto a rack; cool completely.
• Meanwhile, make the "soup": Combine the strawberries, peaches, sugar and lemon juice in a large saucepan. Cook over medium heat until the fruit breaks down, about 15 minutes.
• Puree the sauce with an immersion blender (or in a blender) until mostly smooth. Transfer to a bowl.
• Prepare the pudding as directed; tint with yellow and red food coloring to resemble melted cheese.
• Trim the top of the cake with a large serrated knife to make it level.
• Cut the cake in half horizontally.
• Preheat the broiler. Put the cake on a foil-lined baking sheet and brush the top with the melted butter. Broil until toasted, about 4 minutes.
• Cut the cake in half diagonally. Spread the pudding on the bottom triangles, almost all the way to the edge.
• Cover with the toasted top triangles, pressing gently so the pudding oozes out. Serve with the fruit sauce.
