Homemade Moon Pies

Preheat oven to 350°F. Line 2 baking sheets with parchment paper. Stir together flours, brown sugar, baking soda, salt, and cinnamon in a large bowl until well combined. Cut in cold butter with a pastry cutter or your fingers until butter pieces are pea-sized and fully coated in flour. Fold in honey, water, and vanilla until dough just comes together.

Transfer dough to a lightly floured surface. Pat dough together until a cohesive ball is formed, and no dry bits of flour remain. Roll half of dough 1/4-inch thick. Using a 21/2-inch round cutter, cut 8 rounds of dough, rerolling scraps as necessary. Place dough rounds on 1 prepared baking sheet; repeat with remaining half of dough and baking sheet. Bake in preheated oven 10-12 minutes or until tops are just set, rotating pans halfway through baking. Let cool on pans 3 minutes before transferring to a wire rack to cool completely, about 30 minutes.

Once cookies are cooled, spread about 11/2-2 tablespoons marshmallow creme on the flat sides of 8 of the cookies. Place remaining 8 cookies on top of marshmallow creme, creating 8 sandwiches. Place sandwich cookies on a baking sheet and freeze 30 minutes or until marshmallow creme is set.

Meanwhile, place chocolate and canola oil in a medium microwave-safe bowl. Microwave on 50% power until melted, stirring at 30 second intervals, about 11/2 minutes. Once sandwich cookies are chilled, dip 1 sandwich cookie at a time in melted chocolate. Transfer dipped moonpie to a parchment-lined baking sheet. Repeat with remaining moonies. Let chocolate fully set before serving, about 30 minutes.
