Step 1

In a medium bowl, stir together flour and salt. Set aside.

Step 2

In a large mixing bowl, use an electric hand mixer or stand mixer to beat softened butter on medium speed until very creamy. Add the sugar and cream together until fluffy, about 3-4 minutes.

Step 3

Add the egg and vanilla extract and mix until combined. Add the flour and mix on low speed until just combined. The dough should be very crumbly but holds together when squeezed. Some dry flour patches are fine.

Step 4

Divide the dough into three bowls, about 400g each. Set one bowl aside. Add cocoa powder to one bowl and matcha powder to the other. Use a gloved hand to knead the powders into the dough until just combined.

Step 5

Place each portion of dough in between two sheets of parchment paper. Use a rolling pin to roll out the dough until about 1/8" thick. Transfer all three rolled out cookie doughs to the fridge to chill laying flat for at least 1-2 hours until solid.

Step 6

Line a baking sheet with parchment paper and set aside. Starting with your first sheet of dough, peel the parchment paper off of both sides of the dough but leave the dough sitting on the bottom sheet. Working quickly, use cookie cutters of your choice to cut out shapes from the dough and transfer the cutouts to your lined baking sheet, leaving about 1/2" between each cookie.

Step 7

Chill the entire baking sheet in the fridge while you preheat the oven to 350°F. Re-roll the scraps between the same parchment paper and chill again until solid while you repeat with another sheet of dough.

Step 8

Bake cookies for 12-15 minutes depending on size until slightly golden brown on the edges. Transfer to a cooling rack to cool completely before decorating.

Step 9

To decorate your cookies, dip your cookies in melted chocolate or drizzle it across the cookies in a piping bag with the tip snipped off. Sprinkle crushed nuts on top before the chocolate hardens.

Step 10

Add dollops of jam and melted nutella or biscoff spread on half the sandwich cookies. Sprinkle the top cookies with powdered sugar before pressing on top of the filling.

Step 11

Arrange a selection of cookies in your cookie tin or box starting with the large cookies and filling in the gaps with smaller cookies.
