Sweet Potato Purée

  • 1 large sweet potato, at least 1 pound


  • ¾ cup (157g) packed light brown sugar
  • 2 large eggs (100g)
  • ½ cup (107g) olive oil
  • 3 tablespoons (41g) whole milk
  • 1 tablespoon (6g) pumpkin pie spice

  • ¼ cup cream cheese, softened
  • 2 tablespoons confectioners’ sugar

  • Bake cake until puffed and golden, and a toothpick inserted in center comes out clean, about 40 minutes. Cook cake in pan, on wire rack, for 15 minutes. Carefully remove cake and allow to cool completely on wire rack.

  • Drizzle glaze over cake and enjoy.

To make lifting the cake out of the pan easier, we recommend laying a long thin strip of parchment paper underneath the parchment paper round in the cake pan. This way, when you're ready to life the cake out of the pan, you can use the strip of paper as handles. 
Storage: If you make this ahead of time, we recommend waiting to add the drizzle until right before serving. Store the cake at room temperature overnight or in the refrigerator for up to 3 days. Right before serving, reheat the cake in a low oven (300-degrees) until warmed through. Drizzle the cream cheese glaze over top and serve. 
Wrap leftover cake in plastic wrap and store in the refrigerator for up to 4 days.
