If the name of this recipe doesn’t already have your mouth watering, just wait until we get into the nitty-gritty details. Or should we say, plummy-crumbly details. Slab pies are about the most genius culinary invention since sliced bread—and dare we say, way more fun. This recipe is a glorious creation made with fresh red plums, peaches, our easy homemade Slab Pastry Crust, and only five more simple ingredients you definitely already have in your kitchen (think flour, sugar, and butter). And trust us, everyone will swoon over the cinnamon-spiced crumble topping, especially with a scoop of vanilla ice cream on top. Test Kitchen Tip: Because this crumb-topped pie requires only one portion of pastry, use the leftover dough to make piecrust cookies. Roll out the dough, cut out shapes with cutters, brush with butter, and sprinkle with cinnamon sugar. Bake at 375 ̊F for 10 minutes or until golden brown. Bam! Double the dessert.

Instructions Checklist
  • Preheat oven to 375°F. Unwrap the larger Slab Pastry Crust disk; roll dough out on a lightly floured work surface into an 18- x 13-inch rectangle. Wrap dough around rolling pin; gently fit inside a 15- x 10-inch jelly-roll pan. Turn edges under; crimp. Prick bottom and sides of dough with a fork. Line with parchment paper, leaving a 3- to 4-inch overhang around pan edges. Fill with pie weights or dried beans. Bake 10 minutes. Remove parchment and pie weights. Return crust to oven; bake at 375°F for 5 minutes. Transfer to a wire rack; cool completely, about 30 minutes. (Reserve smaller Slab Pastry Crust disk for another use.)
