- Large mixing bowl
- Rolling pin
- 9×13-inch baking pan

- ¾ cup very cold water (helps bind the dough)
- 3 ½ to 4 pounds apples, peeled, cored and chopped into approximately ½-inch chunks (about 10 cups) (brings sweetness and moisture)
- Squeeze of lemon juice (prevents browning)
- ⅔ to ¾ cup sugar (sweetens the apple filling)

How to Make Apple Slab Pie Bars
Step 1. Begin by measuring the flour into a large bowl. Whisk in the sugar and salt thoroughly to combine them evenly. This initial mixture ensures that the dry ingredients are well-distributed, which is essential for the crust’s flavor and consistency.
Step 2. Next, add the very cold butter cubes to the flour mixture. Coat the butter with the flour before using a pastry blender or a dough cutter to mash the butter into smaller pieces. Aim for a texture similar to coarse crumbs, as this will contribute to a tender, flaky crust.
Step 3. Gradually stir in ½ cup of very cold water into the flour mixture. Mix until the dough starts to come together; it should be moist but not sticky. If it feels too dry, add more water a tablespoon at a time until it holds together.
Step 4. Once the dough has come together, divide it into two equal portions. Form each piece into a disc, wrap them in plastic, and refrigerate for about two hours. Chilling the dough helps it relax, which makes it easier to roll out later.
Step 5. While the dough is chilling, prepare the apple filling. Toss the chopped apple chunks with a little squeeze of lemon juice to keep them fresh. This step also adds a slight tang that enhances the overall flavor of the filling.
Step 6. In a separate bowl, mix together the sugar, cornstarch, and spices. This combination will create a flavorful coating that will enhance the apples and help thicken the filling as it bakes.
Step 7. After the dough has chilled, preheat your oven to 375°F. On a lightly floured surface, roll out the larger piece of dough until it’s large enough to fit your baking pan. This will form the base crust for your slab pie bars.
Step 8. Carefully transfer the rolled-out dough into the baking pan, making sure it fits snugly into the corners. Allow any extra dough to hang over the edges; you can trim it later if needed. This crust will provide a sturdy base for the apple filling.
Step 9. Place the prepared apple filling into the crust, distributing it evenly. Ensure every bit of filling is well-coated with the sugar and spice mixture to enhance the flavor of the apples during baking.
Step 10. Roll out the smaller piece of dough and cover the apple filling. Seal the edges to prevent any juices from leaking out while baking. This will help to keep the filling contained and the crust intact.
Step 11. Brush the top crust with either the heavy cream or the egg wash to give it a lovely golden finish as it bakes. Make sure to cut slits in the top crust to allow steam to escape. This is an important step to prevent sogginess in the crust.
Step 12. Bake the slab pie bars for 40 to 45 minutes, watching for a golden-brown top and bubbling filling. The apples should be tender, and the crust should have a nice golden color. This is your cue that it’s ready to come out of the oven.
Step 13. Allow the pie bars to cool on a wire rack before cutting and serving. This time lets the filling set up a bit, making it easier to slice into neat squares.

Serving Suggestions
These Apple Slab Pie Bars are versatile for many occasions. They make for a pleasant breakfast enjoyed with coffee or tea, and they can be a delightful snack on a quiet afternoon.

Pro Tips for Best Results
- Use very cold butter: This ensures your crust will be flaky. Working with cold ingredients helps maintain that desirable texture in the baked pie.
- Don’t overwork the dough: Mixing too much can lead to a tough crust. Blend just until combined for the best results.
- Ensure proper chilling of dough: Chilling both the dough and the filling helps maintain structure during baking and improves texture.
- Cut slits generously: Adequate steam vents are essential for a crisp crust. Don’t skimp on cuts, or you may end up with a soggier filling.
- Let it cool completely before serving: This not only helps the bars set up nicely for cutting but enhances the flavor as well.
- Adjust sweetness to your taste: Feel free to modify the sugar based on the natural sweetness of your apples.
Common Mistakes to Avoid
- Not chilling the dough enough: This can lead to a tough crust. Always give your dough adequate time to chill, allowing the butter to firm up.
- Using warm butter: Warm butter will meld too much into the flour and can result in a dense crust. Make sure your butter is very cold.
- Skipping the slits in the crust: If you don’t provide steam vents, the pie can bubble over or become soggy. Always cut slits to allow steam to escape.
- Overfilling with apples: Adding too many apples can spill over during baking. Stick to the recommended quantity for the best outcome.
- Not allowing the pie to cool properly: Cutting into it while hot can lead to a messy presentation. Allow proper cooling for clean, recognizable bars.
- Ignoring the resting time after baking: Cutting too soon leads to a filling that leaks out. Always let your bars cool on a wire rack.
Variations & Substitutions
Consider adding a handful of dried cranberries or raisins to the apple filling for an additional texture element. If you enjoy nuts, chopped walnuts or pecans can add a pleasant crunch. You might also explore different spice blends, such as adding ginger for a bit more warmth. Feel free to experiment with the toppings, perhaps a light sprinkle of powdered sugar or a drizzle of caramel for extra flavor.
Storage & Reheating
Store leftover Apple Slab Pie Bars at room temperature for up to two days. For longer storage, place them in the refrigerator, where they’ll keep well for about a week. You can also freeze the baked bars for up to three months. When reheating, use the oven at a low temperature to preserve that flaky crust and warm the filling without making it mushy.
