Ingredients for Chocolate Malt Sandwiches (from Martha Stewart Cookies)
Makes about 1 1/2 dozen
- FOR THE COOKIES
- 2 cups plus 2 tablespoons all-purpose flour
- 1/2 cup unsweetened Dutch-process cocoa powder
- 1/4 cup plain malted milk powder
- 1 teaspoon baking soda
- 1/2 teaspoon coarse salt
- 1 cup (2 sticks) unsalted butter, room temperature
- 1 3/4 cups sugar
- 1 large egg
- 2 teaspoons pure vanilla extract
- 1/4 cup creme fraiche
- 3 tablespoons hot water
- FOR THE FILLING
- 10 ounces semisweet chocolate, coarsely chopped
- 4 tablespoons (1/2 stick) unsalted butter, cut into small pieces
- 1 cup plain malted milk powder
- 3 ounces cream cheese, room temperature
- 1/4 cup plus 2 tablespoons half-and-half
- 1 teaspoon pure vanilla extract
- Preheat oven to 350 degrees. Make cookies: Sift together flour, cocoa powder, malted milk powder, baking soda, and salt. With an electric mixer, beat butter and sugar on medium-high speed until pale and fluffy. Mix in egg, creme fraiche, and hot water. Reduce speed to low; mix in flour mixture.
- Space tablespoon-size balls of dough 3 1/2 inches apart on parchment paper-lined baking sheets. Bake until flat and just firm, 10 to 12 minutes. Let cool on parchment on wire racks.
- Making filling: Melt chocolate and butter in a heatproof bowl set over a pan of simming water, stirring. Let cool. With an electric mixer, beat malted milk powder and cream cheese on medium speed until smooth. Gradually mix in half-and-half, chocolate mixture, and vanilla. Refrigerate, covered, until thick, about 30 minutes. Mix on high speed until fluffy, about 3 minutes.
- Assemble cookies: Spread a heaping tablespoon filling on the bottom of one cookie. Sandwich with another cookie. Repeat. Cookies can be refrigerated between layers of parchment in airtight containers at room temperature up to 3 days.
