Grease a 9x13-inch pan with butter. Arrange pieces of bread in a single layer close together. Pour egg mixture over the bread. Cover and refrigerate several hours or overnight.
Pour off extra egg mixture. Sprinkle 1 Tablespoon sugar over the top. Bake 25-30 minutes until golden brown and a toothpick comes out clean when inserted. Cut into individual portions.
While the French toast is baking make the syrup by combining the Mimosa Brunch Jam, orange juice, lemon juice and butter in a small saucepan. Heat over medium heat until jam and butter are melted. Serve over baked French toast. Garnish with sour cream and mint leaf.
