Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt until well combined.

In a large mixing bowl, cream together unsalted butter, granulated sugar, and powdered sugar using an electric mixer.

Add in the egg, vanilla extract, and almond extract, mixing until smooth and creamy.

Gradually fold the dry mixture into the wet ingredients until just combined.

Scoop tablespoon-sized balls of dough, flattening them to form discs, and create a well in half of them for the filling.

Fill each well with a teaspoon of strawberry jam and top with another disc, sealing the edges.

Bake in the preheated oven for 10-12 minutes until edges are lightly golden. Allow to cool before transferring to a wire rack.

Optionally, drizzle icing and sprinkle colorful decorations before serving.
