Almond Frangipane Cookies

For the almond filling:
2 cups almond flour (200g)
3/4 cup granulated sugar (175g)
1 large egg
3 tbsp unsalted butter, melted (42g)
1 T Bacardi rum
1/2 tsp almond extract

For the cookie dough:
2 sticks unsalted butter, melted (226g)
1 cup + 2 tbsp granulated sugar (220g)
1/2 cup powdered sugar (50g), plus more for garnishing
1 large egg
1 tsp almond extract
1/2 tsp baking soda
1/2 tsp kosher salt
3 cups all-purpose flour (390g)
1 cup sliced almonds

Make the filling : In a bowl, whisk the egg. Mix in the almond flour, sugar, rum, almond extract, and melted butter. Refrigerate until ready to use.

Make the cookie dough: In a large bowl, mix the melted butter, sugars. Add the egg, almond extract, baking soda, and salt. Add the flour and mix thoroughly.

Assemble the cookies: Weigh the dough and divide into 20 portions. Do the same with the almond filling from the refrigerator. Take a cookie dough ball and flatten it into a pancake in-between parchment or wax paper. Put a ball of the filling into the center of the dough pancake. Envelope the cookie dough around the almond filling and roll until smooth. Repeat for all dough balls. Dip in sliced almonds, pressing them into the top of each dough ball.

Bake: Preheat oven to 350F. Bake for 14-16 minutes, until the cookies are just turning golden at the edge. Remove from the oven and move to a wire rack. Dust with powdered sugar.
