Cream Butter & Sugar: In a stand mixer, beat the softened butter, cream cheese, and granulated sugar for about 3 minutes until the mixture is pale and fluffy.
Add Aromatics: Mix in the vanilla bean paste and almond extract until well combined.
Mix Dry Ingredients: Sift in the flour, cornstarch, and salt. Turn the mixer to low speed and mix just until the flour streaks disappear. Do not overmix.
Chill the Dough: Wrap the cookie dough in plastic wrap and refrigerate for at least 60 minutes. This is crucial for a no-crack finish.
Preheat & Prep: Preheat your oven to 350°F (175°C) and line a large baking sheet with parchment paper.
Shape & Press: Roll the dough into 1-inch balls (about 20g each). Use the back of a 1/2 tsp measuring spoon to press a clean "well" in the center of each ball.
Fill with Jam: Fill each indentation 3/4 full with your raspberry jam.
Bake: Bake for 11-12 minutes or until the edges are just set and barely golden.
The Glossy Finish: Remove from the oven and let cool on the pan for 10 minutes. Optional: Add a tiny drop of fresh jam to the centers for a professional, glossy look.
