1-First Step: Prepare the Cookie Dough Cream ½ cup softened butter with ½ cup sugar in a large bowl using a hand mixer until light and fluffy, about 2-3 minutes. This builds air for tenderness. Beat in 1 egg yolk and 1 tsp vanilla extract until smooth. In a separate bowl, whisk 1 cup flour, ¼ cup cocoa powder, and ½ tsp baking powder. Gradually add dry mix to wet ingredients, stirring until a dough forms. Avoid overmixing to keep cookies soft. Wrap dough in plastic and chill for 30 minutes; this prevents spreading.

2-Second Step: Shape and Bake the Cookies Scoop dough into 1-inch balls (about 1 tbsp each) and place 2 inches apart on sheets. Gently flatten slightly with your palm or glass bottom dipped in sugar for even baking. Bake at 350°F for 10-12 minutes until edges firm but centers soft. Cookies will set as they cool. Let rest on sheet 5 minutes, then transfer to wire rack. Cool completely, about 20 minutes.

3-Third Step: Make the Mascarpone Filling While cookies bake, whip 8 oz mascarpone, ¼ cup powdered sugar, and 2 tbsp cooled espresso in a clean bowl until creamy and spreadable, 1-2 minutes. Taste and add more espresso for stronger coffee flavor if desired. Chill filling 10 minutes to firm up for easier sandwiching.

4-Fourth Step: Assemble the Tiramisu Cookies Pair cooled cookies by size. Spread or pipe 1-2 tsp filling on flat side of one cookie. Top with matching cookie, pressing gently. Prepare ¼ cup brewed espresso in a shallow bowl. Quick-dip sandwich bottoms in espresso for 1-2 seconds no soaking to avoid sogginess. Place on rack to set.

5-Final Step: Dust and Serve Sift cocoa powder over tops generously. Let sit 10 minutes for flavors to meld. Serve at room temp or chilled. Pairs well with coffee or milk. Store extras as noted below. Pro tip: For no bake tiramisu cookies recipe vibes, try chilling dough balls without baking for energy bites.
