A winner in ice cream aisles from coast to coast, this combination is both kid-friendly and well-liked by the grown-ups, too. Once the yellow-cake mixture is scraped into a buttered baking pan and smoothed with a spatula, you simply scatter broken Oreo cookies over the top for an easy and playful decoration.

  • Whisk together flour, baking powder, and salt. Combine eggs and sugar in the bowl of a mixer fitted with the whisk attachment. Beat on high speed until thick and pale, about 4 minutes. Add flour mixture; beat just to combine. Add butter and vanilla; beat to combine. Add sour cream; beat until smooth.

  • Scrape batter into prepared pan, smoothing top with a spatula. Sprinkle with cookie pieces. Bake until top springs back when lightly touched and a tester inserted in center comes out clean, 30 to 35 minutes (for 9-by-13-inch) or about 40 minutes (for 8-by-12).

  • Let cool in pan on a wire rack 10 minutes. Using parchment overhangs, lift out of pan and let cool completely on rack. Cake can be stored at room temperature, wrapped in plastic, up to 1 day.
