Steps:

• Heat oven to 350°F (325°F for dark or nonstick pan). In 13×9-inch pan, melt butter in oven. Sprinkle brown sugar evenly over butter. Arrange pineapple slices on brown sugar. Place a cherry in center of each pineapple slice, and arrange remaining cherries around slices; press gently into brown sugar.
• Add enough water to reserved pineapple juice to measure 1 cup. Make cake batter as directed on box, substituting pineapple juice mixture for the water. Pour batter over pineapple and cherries.

Baked Alaska:

Ingredients

Vegetable oil, for brushing

1-pint raspberry, passion fruit or other sorbet, softened

1-pint vanilla ice cream softened

1-quart chocolate ice cream softened

1 cup chocolate wafer crumbs (about 17 crushed wafers)

1 loaf pound cake

1 cup egg whites (about 6 large), at room temperature

Pinch of cream of tartar

1 cup sugar

Steps:

• Make the ice cream cake: Brush a 3-quart metal bowl with vegetable oil; line with plastic wrap. Fill the bowl with scoops of the sorbet, vanilla ice cream and half of the chocolate ice cream, alternating small and large scoops to create a mosaic of colors and shapes. Place a piece of plastic wrap on top of the ice cream; press down to close the gaps between scoops and even out the surface. Remove the plastic wrap, sprinkle the ice cream with the wafer crumbs and re-cover with the plastic wrap, pressing gently. Freeze until set, about 30 minutes.
• Remove the wrap and spread the remaining chocolate ice cream in an even layer on top of the crumbs. Cut the pound cake into 1/2-inch-thick slices; completely cover the ice cream with the slices, trimming as needed (you’ll use about two-thirds of the cake). Cover with fresh plastic wrap and freeze until firm, at least 2 hours or up to 2 days.
• Make the meringue: Whip the egg whites and cream of tartar in a large bowl with a mixer on medium-high speed until foamy, about 2 minutes. Gradually beat in the sugar on high speed until the whites are glossy and hold stiff peaks.
• Remove the top layer of plastic wrap, then invert the cake onto a parchment-lined baking sheet. (If necessary, let the cake stand overturned until it slips out.) Remove the rest of the plastic wrap and cover the ice cream completely with the meringue, making the dome-shaped top slightly thicker than the sides. Form swirly peaks in the meringue using the back of a spoon. Freeze for at least 3 more hours.
• Preheat the oven to 500 degrees. Bake the cake until the meringue peaks are golden, about 4 minutes, or brown the meringue with a blowtorch. Let the cake soften at room temperature for 5 to 10 minutes before slicing. Freeze any leftovers.
