• Sift together the flour, baking powder, and sugar in a mixing bowl.
• Cut in the butter, and mix with a dough hook or by hand until the butter is the size of small peas. You can also add the mixture to a food processor.
• Add in one beaten egg and mix until the dough comes together. It will still be a bit crumbly, but it should generally form a ball.
• Add ⅔ of the shortbread mixture in a 9 in round pan or 8x8 pan.
• If you are using store-bought marzipan, roll it out until it is the shape of your pan, then add it on top of the. shortbread.
• Use the remaining shortbread to create a lattice pattern on top of the marzipan.
• Brush the strips of the lattice with an egg wash
• Bake at 350° for 35-40 min

Homemade marzipan

• To make marzipan from scratch, combine the blanched almond flour, powdered sugar, egg white, and water in a bowl and mix well until it forms a paste. Use this for the marzipan filling between shortbread layers.
