Horizontal slices of rich brownie cake make dramatic stripes in this striking frozen dessert, which features all the fixings of an old-fashioned sundae -- and then some. Two kinds of ice cream -- vanilla and strawberry -- are used as the fillings, along with crunchy peanut butter and crushed raspberries. Everything is layered in a loaf pan before freezing, slicing, and serving -- with whipped cream, sugared peanuts, and cherries on top.

Ingredients

Cake

Vegetable-oil cooking spray
⅔ cup all-purpose flour
¼ cup Dutch-process cocoa powder
¾ teaspoon coarse salt
½ teaspoon baking powder
1 stick unsalted butter, room temperature
1 cup sugar
2 large eggs, room temperature
1 teaspoon pure vanilla extract
⅓ cup whole milk
4 ounces bittersweet chocolate, preferably 61% cacao, melted

Assembly

½ cup crunchy peanut butter
1 ¼ cups vanilla ice cream, softened
⅓ cup crushed raspberries
1 ½ cups strawberry ice cream, softened
Lightly sweetened whipped cream
Sugared Peanuts
Maraschino cherries, for serving

Directions

Cake: Preheat oven to 375 degrees. Coat a 9-by-13-inch baking pan with cooking spray. Line with parchment, leaving overhang on long sides; coat parchment with cooking spray. Whisk together flour, cocoa, salt, and baking powder in a bowl.
In a large bowl, beat butter with sugar on medium speed until pale and fluffy, about 3 minutes. Add eggs, one at a time, beating until smooth. Beat in vanilla. With mixer on low speed, add flour mixture in three batches, alternating with milk in two additions, beating until combined. Beat in melted chocolate.
Transfer batter to prepared pan, smoothing top with an offset spatula. Bake until set on top but still wobbly in center, about 15 minutes. Let cool completely in pan on a wire rack.
Assembly: Line an 8 1/2-by-4 1/2-inch loaf pan with plastic wrap. Use parchment to lift brownie from baking pan. Cut crosswise into 3 pieces, one piece cut to fit bottom of loaf pan exactly, the next slightly wider, and the last widest of all (to match size of pan, which gets wider toward top).
Place smallest brownie piece, top-side up, in bottom of lined loaf pan. Spread peanut butter over top, then vanilla ice cream. Place second-largest brownie piece, top-side down, on ice cream. Spread with raspberries, then strawberry ice cream. Top with final brownie piece, topside down. Cover with plastic wrap and freeze until firm, at least 6 hours and up to 1 day.
Run a butter knife around edges to release lined cake from pan, then use plastic to remove cake and place on a serving platter. Top with whipped cream and sprinkle with peanuts. Slice with a sharp knife, wiping blade clean between each. Serve each slice with more peanuts and a cherry.
