Second Day Apple Squares

These apple squares have a secret weapon: patience.

A buttery brown sugar crumb mixture does double duty here. Part of it gets pressed into the pan as a shortbread-like base. The rest gets mixed with sour cream, egg, cinnamon, and vanilla to create a tender batter loaded with chopped fresh apples.

They’re good straight from the oven, but the real magic happens when you let them sit for a full 24 hours. That resting time lets the moisture from the apples seep into the crumb layers, creating a dense, chewy texture that’s miles ahead of day-one.

Hence the name.

Pro Tips

• Peel and chop the apples small so they bake through completely. Big chunks stay firm and can make cutting difficult.
• Use a tart apple like Granny Smith for the best contrast against the sweet brown sugar base.
• Store loosely covered at room temperature. Wrapping them tightly traps moisture and softens the crumb topping too much.
• Optional chopped walnuts or pecans in the crumb layer add a nutty crunch that pairs beautifully with the apple.
