Preheat Oven and Prepare Muffin TinSet your oven to 350°F (175°C). Lightly grease a jumbo muffin tin with non-stick spray and dust with flour. This ensures the cookies bake evenly and the crumble crust holds its shape.
Make the Crumble BaseIn a large mixing bowl, cream together softened butter, granulated sugar, powdered sugar, vanilla, and almond extract for 1-2 minutes until smooth. Gradually add flour and salt, mixing just until combined. The dough should remain slightly crumbly—overmixing can lead to tough cookies.
Form Cookie BaseSpoon approximately 1/4 cup of dough into each muffin well. Press gently to line the bottom and sides, creating a small well in the center for the jam. Avoid overpacking to maintain a tender, crumbly texture.
Add Raspberry FillingFill each cookie center with 1/2 to 1 tablespoon of seedless raspberry jam. For more flavor, slightly overfill, but be careful of spilling during baking.
Top with Crumble and BakeSprinkle remaining crumble over each cookie to form a crunchy topping. Bake for 18-22 minutes, until the edges are lightly golden and the jam thickens. Check at 18 minutes to avoid overbaking.
Cool and ServeAllow cookies to cool completely in the tin. Use a knife to gently loosen edges before serving. Enjoy at room temperature for best flavor and texture.
Notes
Notes about the recipe: These cookies are flexible and forgiving, perfect for beginner and advanced bakers alike. The crumble topping can be adjusted for more or less crunch, and the jam center can be swapped for your favorite fruit preserves. Baking in a jumbo muffin tin ensures a perfectly thick crust to hold the jam filling, giving each bite a rich, decadent flavor.
