pumpkin dump cake
-
2 1/2
cups
(20 1/2 oz; 580 g) pumpkin puree -
2
eggs - sugar substitute equivalent to 2 cups sugar
-
1/2
cup
sunflower oil -
1
teaspoon
salt -
1 1/4
tsp
pumpkin spice -
1
cup
all-purpose flour -
1
cup
whole wheat flour -
2
teaspoons
baking powder
-
Preheat the oven to 325°F (163°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper for easier cleanup.
-
In a medium mixing bowl, combine the pumpkin puree, eggs, sugar substitute (measured to equal the sweetness of 2 cups sugar), sunflower oil, salt and pumpkin spice. Mix until smooth and homogeneous.
-
Add the all-purpose flour, whole wheat flour and baking powder to the bowl. Stir just until the dry ingredients are incorporated and you have a uniform batter—avoid overmixing to keep the cake tender.
-
Pour the batter into the prepared 9×13-inch pan and spread it evenly. Place the pan on the middle rack of the preheated oven.
-
Bake for 50–60 minutes, or until the top is set and a toothpick inserted into the center comes out clean or with a few moist crumbs. Ovens vary—check at 50 minutes and add time as needed.
-
Allow the cake to cool for at least 15–20 minutes before slicing. Cooling helps the texture settle and makes serving easier. Serve warm or at room temperature.
Diabetic-friendly approach: This recipe replaces granulated sugar with a sugar substitute measured to the equivalent sweetness of two cups of sugar. Choose a substitute you are comfortable baking with—some are granular and behave much like sugar, while liquid sweeteners may change texture. Always follow manufacturer guidance for ratios when swapping.
Texture and flour blend: The mix of whole wheat and all-purpose flour gives a slightly heartier crumb and adds fiber without overpowering the pumpkin flavor. If you prefer a lighter cake, use 2 cups all-purpose flour instead, but expect a slightly less dense result.
Serving suggestions: Top slices with a small dollop of plain Greek yogurt, a light whipped topping, or a sprinkle of chopped nuts for contrast. A touch of cinnamon or extra pumpkin spice on top enhances aroma and presentation.
Storage: Store leftover cake in an airtight container in the refrigerator for up to 4–5 days. For longer storage, wrap tightly and freeze portions for up to 1–2 months; thaw in the refrigerator overnight before serving.
Variations: Add a handful of chopped pecans or walnuts to the batter for crunch, or gently fold in 1/2 cup of sugar-free chocolate chips for a different flavor profile. If you like more pronounced spice, increase pumpkin spice by 1/4 to 1/2 teaspoon.
Baking tip: Because pumpkin puree contains moisture, check doneness with a toothpick and avoid overbaking to keep the cake moist. If the top browns too quickly, tent loosely with foil during the final 10–15 minutes of baking.
