In a large bowl, whisk together the all-purpose flour, powdered sugar, baking powder, and salt.
Add the cold butter, and using your fingertips or a pastry blender, cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
Add the lemon juice, lemon zest, and egg. Knead until a dough forms. Wrap in plastic wrap and refrigerate for 30 minutes to rest.
Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper.
On a lightly floured surface, roll out the dough to a thickness of 3-4 mm. Use cookie cutters to cut out round shapes. Cut a smaller hole in the center of every other circle.
Place the cookie rounds onto the prepared baking sheet and bake for 10-12 minutes, or until lightly golden brown.
Let the linzer cookies cool completely. Spread the plain rounds with vanilla pastry cream, and then top with the cookies that have holes in the center.
Before serving, dust with powdered sugar and garnish with thin lemon slices or a vanilla bean.
