A boxed spice cake mix gets a pumpkin boost, then topped with a butter-cream cheese frosting that bakes into gooey pockets. Serve warm with vanilla bean ice cream for a Halloween treat that's as fun to make as it is to eat.

Ingredients

Directions

  1. Set oven to 350°F. Coat a 9x13-inch pan with non-stick spray. Put aside.
  2. Combine spice cake mix, oil, water, eggs, pumpkin puree, and pumpkin pie spice using a spatula or hand mixer on low speed. Pour this batter into the pan. Set aside.
  3. In a saucepan, melt together butter and cream cheese, stirring often. Alternatively, microwave them in a bowl at 50% power for 3 minutes, then stir and add more time if needed until fully melted.
  4. Using a mixer on low, incorporate powdered sugar until thick. Transfer this frosting to a piping bag or zip-top bag and drizzle over the batter. Or drop spoonfuls over the batter, then swirl with a knife or spatula.
  5. Bake for 40 to 45 minutes. The cake is ready when it no longer jiggles when you shake the pan. A toothpick test won't work because the baked-in frosting keeps it gooey.
  6. Let cake cool. Serve with a scoop of Hudsonville Vanilla Bean ice cream. Store leftovers covered in the fridge.
