Conversation Hearts Recipes

Steps:

• Whisk together flour, baking powder, and salt in a large bowl. Cream butter and sugar with a mixer on medium speed until pale and fluffy. With mixer running, add egg and vanilla. Reduce speed to low. Add flour mixture gradually, beating until just incorporated. Divide dough in half; flatten each half into a disk, and wrap each in plastic. Refrigerate until firm, at least 1 hour (or overnight).
• Preheat oven to 325 degrees with racks in top third and lower third. Let 1 disk of dough stand at room temperature just until soft enough to roll, about 10 minutes. On a lightly floured work surface, roll out dough to just under 1/4-inch thickness, adding more flour as needed to keep dough from sticking. Cut out cookies with a 2-inch heart cutter, and place them 2 inches apart on a parchment-lined baking sheet. Roll out scraps once, and repeat. Repeat with remaining disk of dough. Freeze cookies until very firm, about 15 minutes.
• Bake cookies, rotating sheets halfway through and switching from top to bottom, until edges turn golden brown, 14 to 16 minutes. Let cool on sheets on wire racks. Cookies will keep, covered, for up to 1 week.
• Divide royal icing into 1/2-cup portions in small bowls. Tint each with a different gel-paste food coloring, starting with just a drop, mixing well, and adding more, drop by drop, to reach desired shade. Transfer 1 bowl of icing to a pastry bag fitted with a 1/8-inch round plain tip. Pipe the outline around edge of each cookie, then fill in with frosting. Poke air bubbles with a toothpick. Transfer decorated cookies to a parchment-lined baking sheet, and let stand uncovered overnight until dry.
• Arrange stamp letters to create desired phrases. (We stamped LUV U, UR A QT, BFF, LYLAS, B MINE, and 2GTBT.) Fold a paper towel into quarters. Squeeze a small amount of red gel-paste food coloring onto a paper towel, and press stamp in coloring. (You may need to blot stamp a few times on a clean paper towel if coloring is too thick.) Lightly press stamp on top of icing in center of each cookie. Let stand until dry, about 30 minutes. Stamped cookies will keep, covered, for up to 3 days.

Steps:

• Preheat the oven to 350˚ F. Coat a 9-inch round and a 9-inch square cake pan (2 inches deep) with cooking spray. Prepare the cake mixes as directed; divide between the pans. Bake until a toothpick comes out clean, 30 to 35 minutes.
• Let the cakes cool, then remove from the pans. Trim the tops of the cakes with a long serrated knife to make them level. Cut the round cake in half as shown.
• Working on a cake board (you can cut the board into a heart shape to fit the cake) or a cutting board, position the 2 half circles of cake against 2 sides of the square cake to make a heart.
• Cover the cake with the white frosting, using the frosting to fill in any gaps between the cakes.
• Combine the marshmallows and water in a large microwave-safe bowl. Microwave, stirring with a rubber spatula, until melted and smooth, 1 to 2 minutes. Add the green food coloring and stir until smooth.
• Transfer the marshmallow mixture to a stand mixer. Gradually add all but 1/2 cup of the confectioners' sugar and beat until combined. Beat in the butter.
• Scrape the marshmallow fondant onto a sheet of parchment and knead in confectioners' sugar until it's no longer sticky. Dust the parchment with more sugar; roll out the fondant until it's large enough to cover the cake, at least 13 by 16 inches.
• Carefully flip the parchment and fondant onto the cake; peel off the parchment. Gently press the fondant against the sides of the cake and smooth with your hands; trim the excess. Brush off the extra sugar.
• Use the wide end of a chopstick to press letters into the fondant (it's best to do this before the fondant dries out). Use a small brush to paint hot pink or red food coloring in the letter indentations.
