Delicious apple pie bars inspired by Ina Garten’s recipe featuring a buttery shortbread crust, warmly spiced apple filling, and a rustic crumbly topping. Baked in an 8×8 inch pan, easy to slice and serve warm with ice cream or at room temperature.
Choose firm, slightly tart apples like Braeburn, Pink Lady, or Granny Smith, or a mix, for great texture and balanced sweetness., Don’t skip lining your pan with parchment and leaving an overhang—it makes removing and cutting the bars much easier., Chilling the crust after pressing it into the pan helps it hold its shape and prevents shrinking during baking., Add cornstarch at the end of cooking the apples to thicken the filling without making it gluey or too stiff., If topping browns faster than rest, tent bars with foil for last 10 minutes of baking., Let bars cool completely before slicing to get clean edges; best warm but slice tidier when cooled., Nut-free option: skip walnuts and add 1-2 tablespoons extra flour., Oat streusel topping alternative: rolled oats, brown sugar, melted butter sprinkled over apples instead of crumb topping., Caramel apple bars: drizzle warm caramel sauce before serving., Spice variations: swap cinnamon for cloves (1/4 tsp) or pumpkin pie spice (1/2 tsp)., Fruit swap: pears or mix of apples and pears can be used., Store at room temp airtight container up to 2 days; refrigerate up to 5 days; or freeze up to 2 months., Reheat in 325°F oven 10-15 minutes or microwave 20-30 seconds (watch for sogginess).
