7Up Sheet Cake

Preparation

1. Step 1

   Heat oven to 350 degrees. Grease a rimmed 13-by-18-inch half sheet pan and line with parchment paper.

2. Step 2

   In the bowl of a stand mixer, cream together the butter and granulated sugar at medium speed. Add eggs one at a time, blending until incorporated, then add extract and both zests.

3. Step 3

   Reduce mixer speed to low. Add about ⅓ of the cake flour, followed by half of the 7Up, blending until combined. Repeat with flour, then 7Up, then the remaining flour, until evenly blended.

4. Step 4

   Transfer the batter into the prepared pan, smooth the top with a spatula and bake until golden brown and set in the middle, about 35 minutes.

5. Step 5

   While the cake bakes, make the glaze: In a medium bowl, combine the confectioners’ sugar, 7Up, lemon juice and both zests. Whisk until smooth. (If a skin forms on top, give it a stir.)

6. Step 6

   Let the cake stand cool completely in the pan, then spread the glaze onto the cake, and serve directly from the pan.
