Let me share my favorite fall treat these Apple Harvest Squares bring back such wonderful memories of apple picking with my family. Every autumn when the apples are perfectly crisp and sweet I whip up a batch and the whole house smells like warm cinnamon and butter. The combination of tender apples buttery crust and that crunchy coconut walnut topping is pure comfort food magic.

What Makes These So Special

These squares are like having the best parts of apple pie in an easy-to-serve bar. The buttery cookie crust is so much simpler than pie dough but tastes just as amazing. My kids love helping arrange the apple slices and sprinkle on that irresistible coconut walnut topping. It's become our favorite way to use up apples from our weekend orchard visits.

What You'll Need

  • Fresh Apples: Cortland or other firm varieties, sliced thinly for even baking.
  • Lemon Juice: Adds a tart balance to the sweetness of the apples.
  • Granulated Sugar: Sweetens the apple layer and enhances the topping.
  • Cinnamon: Brings warm, spiced notes to the baked apples.
  • All-Purpose Flour: Forms the base of the buttery cookie crust.
  • Butter: Adds richness and structure to the crust.
  • Chopped Walnuts: Provides a crunchy texture for the topping.
  • Flaked Coconut: Adds a touch of sweetness and a chewy texture.
  • Vanilla Extract: Enhances the overall flavor of the dessert.

Let's Get Baking

Prepare the Crust
Combine flour and butter in a bowl, mixing until crumbly. Press the mixture into the bottom of a greased 9x13-inch baking dish to form an even crust.
Layer the Apples
Arrange thinly sliced apples evenly over the crust. Drizzle with lemon juice and sprinkle with cinnamon and sugar to taste.
Prepare the Topping
Mix chopped walnuts, flaked coconut, and a touch of vanilla extract in a bowl. Sprinkle the mixture evenly over the apples.
Bake
Preheat the oven to 350°F (175°C). Bake for 35–40 minutes or until the topping is golden brown and the apples are tender.
Cool and Serve
Allow the squares to cool in the pan before slicing into bars. Serve warm or at room temperature.

My Pro Tips

After making these countless times I've learned a few tricks. Cortland apples are my favorite but any firm baking apple works great. Really press that crust firmly into the pan it makes such a difference in the final texture. And don't skip the lemon juice it keeps the apples from browning and adds the perfect hint of tartness.

Perfect Pairings

We love serving these squares warm with a scoop of vanilla ice cream the way it melts into the warm apples is heavenly. For breakfast (yes I said breakfast!) they're amazing with a hot cup of coffee. And when I'm feeling extra indulgent I'll drizzle some caramel sauce over the top.

Keep Them Fresh

These squares stay delicious for days when stored properly. I keep them in an airtight container at room temperature they'll last about three days though they rarely make it that long in my house. For longer storage pop them in the fridge and just warm them up slightly before serving.

Mix It Up

Don't be afraid to experiment with this recipe. Sometimes I'll swap the walnuts for pecans or add some dried cranberries to the topping. For my gluten-free friends I use a cup-for-cup gluten-free flour blend in the crust and it works beautifully. The basic recipe is so solid you can really make it your own.

Why They're Special

These Apple Harvest Squares have become our family's favorite fall tradition. There's something about the combination of fresh apples warm spices and that nutty coconut topping that just makes everyone happy. Plus they're so much easier than pie but just as impressive.

Make Them Your Own

The topping is where you can really get creative. Try a maple glaze drizzle some crushed toffee bits or a dusting of powdered sugar. Each variation adds its own special touch. My daughter loves sprinkling extra cinnamon sugar on her portion before it goes in the oven.

Perfect for Any Occasion

Whether you're hosting a fall gathering needing a potluck dish or just craving something sweet these squares never disappoint. They're casual enough for an after-school snack but special enough for holiday dessert tables. Once you try them you'll understand why they've become such a beloved recipe in our house.
