Strawberry Pop Tart Slab Pie Recipe – Easy Flaky Jam Dessert

There’s nothing quite like the sweet aroma of warm jam mingling with flaky pastry to draw you into the kitchen. My Strawberry Pop Tart Slab Pie Recipe starts with golden puff pastry singing softly as it bakes, a glossy white drizzle crowning its surface. After three rounds of tweaks—flouring the board slightly less, stretching the jam a hair thinner, and dialing the bake time to the minute—I discovered how to get those perfect golden edges and a silky-smooth glaze every time.

A Little Background

On a rainy spring afternoon, I first paired strawberry jam with puff pastry for a playful riff on classic toaster pastries. The idea fluttered in my mind until I tested it again and again, perfecting the jam-to-pastry ratio so each forkful is tender with a slight bite and a gentle steam of fruity warmth.

Key Ingredients for Strawberry Pop Tart Slab Pie Recipe

  • Frozen puff pastry sheets (2): Flaky base—thaw in the fridge to keep them firm.
  • Strawberry jam (1 cup): Use a fruit-forward variety for best texture.
  • Egg + water (1 egg beaten with 1 Tbsp water): Creates a glossy seal around the filling.
  • Powdered sugar (1½ cups): Sift first for a lump-free glaze.
  • Heavy cream or milk (2 Tbsp): Adjust for glaze thickness; milk lightens flavor.

How to Make Strawberry Pop Tart Slab Pie Recipe

  1. Preheat the oven to 400°F and line a rimmed baking sheet with parchment. Unfold one pastry sheet, lay it flat, and dollop the cup of strawberry jam, spreading to within a ½-inch border. (Prep note: in my first batch I spread too close to the edges—jam seeped out!)
  2. In a small bowl whisk the egg with 1 tablespoon water; brush this egg wash onto the exposed pastry border. Place the second sheet on top, pressing edges to seal and crimp with a fork. Cut four 1-inch slits across the top for steam to escape.
  3. Bake until puffed and golden around the edges, 18–20 minutes, watching for that nutty toasted scent and gentle sizzling at the corners. In one trial I found 19 minutes gave the most even color.
  4. Let the slab cool completely on the sheet (about 20 minutes). Meanwhile, whisk 1½ cups powdered sugar with 2 tablespoons cream until glossy and smooth. Drizzle generously over the cooled pastry and garnish with crushed freeze-dried strawberries if you like.

Pro Tips & Troubleshooting

  • Keep your work surface lightly floured so pastry doesn’t tear but still seals neatly.
  • If jam leaks, check that egg wash layer is even—add a second brush if needed.
  • Swap in mixed-berry preserves for a seasonal twist in late summer.
  • To halve the slab, cut pastry sheets in half and bake two smaller slabs, reducing bake time to ~15 minutes.

Storage & Make-Ahead Guide

Store cooled slices in an airtight container at room temperature up to 2 days or refrigerate up to 5 days (note: in my storage test they stay flaky through day 4). For longer keep in the freezer up to 1 month—thaw at room temperature, then crisp in a 350°F oven for 5 minutes. Always refrigerate within 2 hours of baking for food safety.

Serving Suggestions

Cut into rectangles and serve alongside a dusting of fresh mint leaves or with a scoop of vanilla ice cream for brunch. It also pairs beautifully with a café au lait or a tall glass of chilled milk.
