Can I make these cookies ahead of time?
Yes. Bake and cool completely, then store in an airtight container at room temperature for up to 5 days. Add the almond glaze within 1–2 hours of serving for best texture.
What's the best way to create a uniform thumbprint indent?
Use the back of a measuring spoon or your thumb dipped lightly in flour to press a shallow well into each cookie before baking. Avoid pressing too deep, as the cookie will spread slightly in the oven.
Can I substitute the raspberry jam?
Yes. Strawberry, apricot, or blackberry jam work equally well. Use the same amount (1/4 cup) and ensure the jam is thick enough not to leak during baking.
How do I know when the cookies are done baking?
They should be pale golden at the edges and set but still soft in the center, typically 10–12 minutes. They will firm up as they cool.
Can I make this recipe without almond extract?
Yes. Omit the almond extract and use 1 tsp vanilla extract in the glaze instead, or use just powdered sugar and water for a plain glaze.
