Mom’s Flat Apple Pie

Mom’s Flat Apple Pie – A Simple, Comforting Classic

There’s nothing quite like the aroma of Mom’s Flat Apple Pie baking in the oven. This easy, sheet-pan version of the classic double-crust apple pie combines tart Granny Smith apples, a crunchy Corn Flakes base, and a delicate sweet frosting that perfectly balances the fruit’s natural tang. It’s a dessert that’s both nostalgic and effortlessly delicious, perfect for family gatherings, holidays, or just a cozy night at home.

Unlike traditional pies, this flat apple pie is simple to assemble, requires minimal rolling, and bakes evenly, making it a stress-free way to enjoy a homemade treat.

Ingredients and Their Roles

• 5–6 Granny Smith apples, thinly sliced: Tart and crisp, these apples provide structure and flavor that hold up perfectly in the oven.
• 2 cups Corn Flakes: Adds crunch to the pie base, giving a unique texture contrast to the tender apples.
• 1/2 cup unsalted butter, melted: Binds the Corn Flakes and adds rich buttery flavor.
• 1/2 cup brown sugar: Sweetens the base while caramelizing slightly in the oven for added depth.
• 1 tsp cinnamon: Classic spice that complements the tartness of the apples.
• 1/2 tsp nutmeg: Adds warmth and aromatic complexity.
• 1–2 tbsp all-purpose flour: Helps thicken any juices released from the apples during baking.
• 1 cup powdered sugar: For the thin frosting, adds sweetness without overwhelming the fruit.
• 2–3 tbsp milk: Creates a smooth, pourable consistency for the frosting.

Step-by-Step Instructions for Mom’s Flat Apple Pie

1. Preheat the Oven: Set your oven to 350°F (175°C). Lightly grease a 9x13-inch sheet pan or line it with parchment paper to prevent sticking.
2. Prepare the Corn Flakes Base: In a medium bowl, combine the Corn Flakes, melted butter, brown sugar, cinnamon, and nutmeg. Toss gently until the flakes are evenly coated and sticky.
3. Layer the Base: Press the Corn Flakes mixture firmly into the bottom of the prepared sheet pan, creating an even layer that will support the apples.
4. Prepare the Apples: Peel and thinly slice the Granny Smith apples. Toss them with 1–2 tablespoons of flour to help absorb excess juices during baking.
5. Assemble the Pie: Spread the apples evenly over the Corn Flakes base. Make sure the slices overlap slightly to create a uniform layer that will bake beautifully.
6. Bake: Place the sheet pan in the preheated oven and bake for 40–45 minutes, or until the apples are tender and slightly golden around the edges. The Corn Flakes base should be crisp and fragrant.
7. Make the Frosting: While the pie is baking, whisk together the powdered sugar and milk until smooth and pourable. Adjust the consistency with a little extra milk if needed.
8. Drizzle and Serve: Once the pie is slightly cooled (about 10 minutes), drizzle the frosting evenly over the top. Slice into squares and serve warm or at room temperature for a comforting, sweet treat.

Pro Tips for Perfect Mom’s Flat Apple Pie

• Use Tart Apples: Granny Smith or Honeycrisp apples give a nice balance of sweetness and tang.
• Even Slices: Slice the apples uniformly to ensure consistent baking and texture.
• Prevent Sogginess: Toss apple slices with flour to thicken juices and keep the Corn Flakes base crisp.
• Optional Enhancements: Sprinkle a pinch of cinnamon sugar over the apples before baking for extra flavor.
• Make Ahead: Assemble the pie and store in the fridge for a few hours before baking — perfect for busy mornings.

Serving Suggestions

• Serve warm with a scoop of vanilla ice cream for a classic dessert pairing.
• Drizzle with caramel sauce for an extra indulgent twist.
• Perfect for brunch alongside coffee or hot tea.
• Cut into small squares for easy serving at parties or potlucks.
