Store-bought piecrust is the secret to this dessert. Just brush with melted butter, sprinkle with brown sugar and spices, cut in squares and pop in the oven for a few minutes.
Preheat oven to 400°F. Unroll piecrust according to package directions using the microwave method. Place on a lightly floured surface. Brush piecrust with melted butter. Sprinkle with brown sugar and pie spice.
Use a pastry wheel or pizza cutter to cut dough into 1 1/2- to 2-inch squares (some of the edges may be smaller). Place on an ungreased large cookie sheet, leaving a small space between pastries.
Bake about 8 minutes or until golden brown. Serve warm or cool.
