Ingredients:
- 2 cups All-Purpose Flour (plus extra for dusting)
- 1 cup Blanched Ground Almonds (Almond Flour)
- 3/4 cup Confectioners' Sugar, sifted
- 1/2 tsp Fine Sea Salt
- 1 tsp Lemon Zest (zest of 1 small lemon)
- 1 cup (2 sticks) Unsalted Butter, cold and cubed
- 1 large Egg Yolk
- 1 tsp Vanilla Extract
- 1/2 cup Seedless Raspberry Jam
- 1/2 cup Confectioners' Sugar (for dusting)
Instructions:
- Combine Dry Ingredients: Whisk together the flour, ground almonds, sugar, salt, and lemon zest in a large bowl or the bowl of a stand mixer.
- Cut in the Butter: Add the cold, cubed butter. Mix on low speed until the mixture resembles coarse sand and no large pieces of butter remain.
- Add Wet Ingredients: Add the egg yolk and vanilla extract. Mix briefly until the dough just comes together into a cohesive mass. Do not overmix.
- Chill: Divide the dough in half. Shape each half into a flat disk, wrap tightly in cling film, and refrigerate for a minimum of 90 minutes, or up to 2 days.
- Preheat and Prep: Preheat the oven to 170°C (340°F). Line baking sheets with parchment paper.
- Roll the Dough: Remove one disk from the fridge. Working quickly, lightly flour a surface and roll the dough out to an even thickness of about 3 mm (1/8 inch).
- Cut the Bases: Use the large heart cutter to cut out half of your required bases (solid hearts). Transfer carefully to the prepared baking sheets.
- Cut the Lids: Roll out the second dough disk. Cut the remaining halves with the large cutter. Then, use the small heart cutter to punch out the centre from these 'lids'.
- Second Chill (Mandatory): Place the trays of cut cookies back into the refrigerator for 15 minutes before baking to prevent spreading.
- Bake: Bake the cookies for 12–15 minutes, rotating the tray halfway through, until the edges are lightly golden brown. The centres should remain pale.
- Cool Completely: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them gently to a wire rack to cool completely. They must be entirely cool before assembly.
- Dust the Lids: Place the cooled cookies with the heart cut-outs (the 'lids') on a flat surface. Using a fine mesh sieve, generously dust them with confectioners' sugar.
- Fill the Bases: Warm the raspberry jam slightly. Spread about 1 teaspoon of jam onto the solid cookie bases, keeping the jam within the edges.
- Assemble: Gently place the dusted, cut-out lids on top of the jam-covered bases. Serve immediately or store in an airtight container.
