Ingredients
Preparation
Step 1
Preheat oven to 350Ā°F. On a lightly floured surface, roll out dough 1/8 inch thick. Fit dough into twenty-four 3-inch fluted tart pans, or the cups of a standard muffin tin. Place pans on a rimmed baking sheet; refrigerate or freeze until firm, about 30 minutes. Bake until dry, 18 to 20 minutes. Let cool completely; unmold shells from pans.
Step 2
Place chopped bittersweet chocolate in a heatproof bowl. In a small saucepan over medium heat, bring cream and espresso powder to a simmer. Pour over chopped chocolate, and let stand 5 minutes. Stir until smooth. Fill baked and cooled tart shells with chocolate mixture.
Step 3
Meanwhile, in a heatproof bowl set over (not in) a pan of simmering water, melt white chocolate, stirring. Transfer to a resealable plastic bag; snip a small opening in the corner. Working quickly, pipe 6 dots of melted white chocolate on filling in each tartlet. Using a wooden skewer or toothpick, swirl dots to marbleize. Gently tap tartlets on work surface to settle filling. Refrigerate until set, 1 hour or up to 1 day.
