Optional: powdered sugar or melted chocolate for finishing
Instructions
Cream butter and sugar: In a large bowl, beat the butter and granulated sugar together until light and fluffy, about 1–2 minutes.
Add egg yolk and vanilla: Mix in the egg yolk and vanilla extract until smooth and fully combined.
Combine dry ingredients: In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder.
Make the dough: Add the dry ingredients to the wet ingredients and mix just until a soft dough forms. The dough will be thick but pliable.
Chill: Cover and refrigerate the dough for 30 minutes to prevent spreading.
Preheat oven: Preheat oven to 350°F and line baking sheets with parchment paper.
Shape cookies: Scoop dough into 1½ tablespoon-sized balls and place them about 2 inches apart on the baking sheet.
Create thumbprints: Use your thumb or the back of a rounded teaspoon to press an indentation into the center of each cookie gently.
Fill with jam: Spoon about ½–1 teaspoon of raspberry jam into each indentation.
Bake: Bake for 10–12 minutes, until the edges are set and the cookies look slightly soft in the center.
Cool: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
Notes
Tips for Best Results:
Use thick jam so it stays neatly in the center while baking. If cracks form when making the thumbprint, gently press the dough back together — totally normal. Cookies will firm up as they cool, keeping the centers soft and fudgy.
