Preheat oven to 375F. Prepare a 9 x 13 inch pan with cooking spray and line with parchment paper. Set aside.

In a large bowl, mix together the dry ingredients, the flour, sugar, baking powder and salt. Then cut in the butter with a pastry blender until the butter is mixed in and the mixture resembles small peas. You can also use a food processor.

In a small bowl, whisk together the egg, and the almond and vanilla extracts. Add to the flour mixture and stir to combine. The dough will still be crumbly.

Using clean hands, take 1/2 the mixture and pat into the bottom of the prepared pan. Then spread an even layer of jam over the crust, sprinkle raspberries over the top of the jam. Crumble the remaining shortbread dough over the pan and sprinkle with almonds. Bake in a preheated oven until the bars are golden brown about 30-35 minutes. Let cool on wire rack.

While bars are cooling, mix the ingredients for the glaze. Once bars are cooled drizzle with glaze.
