15 X 21 BAKING SHEET RECIPES

Steps:

• Heat oven to 200C/180C fan/gas 6 and lightly butter and flour a 12 hole fairy cake tin. Lay a sheet of puff pastry on a floured surface and use a rolling pin to roll it out a little, so it's 5 cm bigger than your fairy cake tin.
• Lay the sheet onto the tin, pushing it into the holes. Spoon 1½ tbsp of mincemeat into each hole, then use some of the beaten egg to brush around all of the holes. Lay the other sheet of pastry on top and press to seal. Lightly dust the top with flour.
• Use an 8cm cookie cutter to cut circles around each of the holes, peeling away the excess puff pastry. You will be left with 12 flat-topped pies. Place a flat baking tray over the pies and flip the fairy cake tin upside-down. The pies should slip out of the tin, leaving you with 12 puff pies on a baking tray.
• Press each one around the edges to make sure they're well sealed. Brush them with more of the beaten egg, sprinkle with demerara sugar. Bake for 20 mins, until risen and golden. Allow to cool a little, then serve warm.

Steps:

• Position a rack in center of oven; preheat to 325°F. Very generously butter an 18x13" rimmed baking sheet (do not line with parchment).
• Melt remaining 1/2 cup butter in a small heatproof bowl in the microwave or set over a pot of barely simmering water. Mix sugar, cocoa powder, vanilla, and salt in a medium bowl. Pour butter over and stir until smooth. Add eggs one at a time, stirring vigorously with a wooden spoon or rubber spatula after each addition, until batter is thick, shiny, and smooth. Stir in flour until well incorporated, then beat vigorously for 30–40 strokes. Stir in nuts or chocolate chips.
• Using a spatula, spread batter into a thin, even layer to edges and into corners of prepared sheet (batter will seem scant but brownies will rise to about 1/4" thick).
• Bake brownies until firm to the touch and a tester inserted into the center comes out with moist crumbs (not runny batter) attached, 15–18 minutes.
• Transfer to a wire rack and let cool completely. Cut into 36 pieces and serve.
• Brownies can be made 5 days ahead. Store in an airtight container at room temperature, or freeze up to 6 months.
