  • These apple bars will feed a crowd.

Just days ago it was hot and humid as I headed out to my morning yoga practice…but there was definitely a nip in the air today. Armed with just my car keys, mat, and towel, I had to buzz back inside for a jacket to warm my goose bump-covered bare arms.

The days were growing shorter, a sure sign that autumn was on its way. To usher in the season, I always turn to apples and cinnamon…so I whipped up this delightful pan of cinnamon apple squares for a neighborhood ‘Fall Crawl.”

Frequently Asked Questions

What is a Slab Pie?

A slab pie is a pie baked in an oblong, jelly-roll type pan. There is a bottom crust, a filling, and a top crust. Perfect for a crowd, square slices are served instead of the typical pie wedges.

How do You store a Slab Pie?

It will keep at room temperature for a day or two. But because of the fruit filling,  the crust will eventually soften. So to keep it fresh longer, store it in the refrigerator after a couple of days. Just gently warm the slices before serving.

Can You Freeze Apple Bars?

These bars will freeze well if wrapped airtight. Just defrost overnight in the refrigerator and rewarm to serve.

What Apples are Best for these Apple Squares?

My mom’s recipe called for Jonagolds, but I like a combination of Granny Smith and Golden Delicious apples. Any baking apple will work, but it’s nice to use more than one variety (sweet and tart, soft and firm) to make a more interesting, more flavorful filling.

How to Make Apple Pie Bars

This apple slab pie recipe will easily feed a crowd. And apples and cinnamon are such a delightful combination, especially when autumn arrives.

  • Make the crust recipe, cut in half, wrap and chill.
  • Peel, core, and slice the apples. Mix them with sugar, cinnamon, etc.
  • Preheat oven to 400º.
  • Roll one ball of dough large enough to fit the bottom of a jellyroll pan. Arrange apples over dough.
  • Roll out the second ball of dough and cover apples with a single layer of crust or strips if you want to make a lattice crust.
  • Pinch edges to seal. Whisk egg whites and brush over crust (only if you don’t want to use the glaze).
  • Cut vents in several places if needed. If you make a lattice topping, there will already be lots of vents!
  • Glaze with egg whites if desired. A sprinkle of coarse sugar is a nice touch, too.
  • Bake until the crust is brown and the apples are tender.
  • Make the powdered sugar glaze if you’d like (don’t sprinkle the crust with sugar if you want to glaze).
  • Serve warm or cold.

Tips for Making Apple Squares

  • This is an old recipe from my mom. I varied it today by making a lattice crust, but for years I topped it with a solid crust, like a large apple slab pie.
  • Note that butter gives a wonderful flavor to a pie crust. Shortening makes the dough easier to work with and makes more defined edges.
  • Make sure to use good pie apples. I like a combination of apples for the best flavor. If you can buy local apples, ask the proprietors about their favorite pie apples.
  • PRO-Tip: I’ll often combine firm, tart Granny Smith apples with a few sweet, softer Golden Delicious apples. Using a combination of baking apples gives a delicious depth of apple flavor.
  • I like to line up my apple slices in rows as it keeps the filling level. This makes it easier to weave the lattice topping. Remember, you can always make a solid top crust, but make sure to add a few slits so that the steam can release as it’s baking.
  • This apple slab pie is so much easier than baking up two apple pies, so it’s perfect if you’re making it for a gathering. Plus you still get all the same delectable flavors.
