Jam Sandwich Cookies

Makes 18
4 cups Everyday Baking Mix, spooned and leveled
1 cup (2 sticks) cold unsalted butter, cut into pieces
1/2 cup whole milk
3/4 cup seedless jam or jelly

Preheat oven to 350°F. Line two baking sheets with parchment paper. In a food processor, pulse baking mix and butter until mixture resembles coarse meal. Add milk; pulse until a dough forms. Drop dough by heaping tablespoons onto sheets, 4 inches apart. (You will fit about 9 cookies to a sheet; bake in two batches to make a total of 36 cookies.) Bake until cookies begin to turn golden but center is still pale, 12 to 14 minutes, rotating sheets halfway through. Transfer to a wire rack to cool completely. Spread flat side of half the cookies with 2 teaspoons jam each; sandwich with remaining cookies.
