Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
Cream the butter and sugar together until it’s fluffy like a cloud — about 2-3 minutes.
1 cup unsalted butter, softened, 2/3 cup granulated sugar
Add vanilla and almond extract (if using). Mix until smooth.
1/2 tsp vanilla extract, 1/4 tsp almond extract
Add flour and salt. Mix on low speed or by hand until the dough comes together. It should be soft but not sticky — if it's a bit crumbly, just knead it a little with your hands.
1/4 tsp salt, 2 cups all-purpose flour
Roll the dough into 1-inch balls and coat them in granulated sugar. Place them a couple inches apart on your baking sheet.
Press your thumb (or back of a teaspoon) into the center of each ball to make a little well. Be gentle so the cookie doesn't crack too much.
Spoon in the jam! Fill each indent with about 1/2 tsp of strawberry jam — not too much or it’ll overflow like a lava pit.
1/2 cup cup strawberry jam
Bake for 12–14 minutes, or until the edges are juuust turning golden. Let them cool on the pan for 5 minutes, then move to a wire rack.
Optional but fabulous: Once cool, dust with a light shower of powdered sugar like fairy dust.
