    How to Make Easy Pumpkin Squares

    Numbered process collage showing the four steps to making this Pumpkin Squares Recipe.

    Split Cake Mix.  Open the box of yellow cake mix and take out one cup of the Mix and put it into a small bowl. Set aside to use later.

    1. Bottom Layer.  In a different bowl, combine the remaining yellow cake mix, with the 8 tablespoons of melted butter, and 1 egg. Spread this mixture out, covering the bottom of the prepared baking sheet.
    2. Middle Layer.  Next, mix together in a small bowl, 16 ounces pumpkin butter, the remaining 2 eggs, and the 2 tablespoons of milk. Layer this mixture evenly on top of the mixture already covering the bottom of the baking sheet.
    3. Topping.   Mix 1 cup of yellow cake mix previously set aside with 1 tablespoon of flour, ¼ cup of sugar, and 1 teaspoon of cinnamon. Then, using a pastry cutter or a fork, cut in 4 tablespoons of cold butter until all the butter is about pea-sized and mixed in evenly throughout the topping. Next, layer the Topping evenly over the top of the previously layered ingredients on the baking sheet.
    4. Bake.  Bake at 350°F  for 35 minutes until golden brown and delicious.

    Expert Tips

    • Don't overmix. Overmixing the batter can lead to tough squares. Mix just until the ingredients are combined.
    • Let them cool completely. Allow the squares to cool completely before frosting or cutting them. This will prevent them from crumbling.

        Thanks JoLynn! No, they do not. Countertop is fine. I do love to freeze them, however. They're delicious cold, right out of the freezer.

      Is 16 oz pumpkin butter by weight or 16 oz liquid measure? Thank you!

        Hey Lynn, By weight. 16 Ounces of Pumpkin Butter plus or minus will work fine. This ingredient amount is pretty flexible. Now you've got me craving these!
