Ingredients for the pumpkin layer and crunchy pecan topping
Pumpkin custard layer
- 1 (15-oz) can pumpkin puree (not pumpkin pie mix)
- 1 cup heavy cream
- 4 large eggs
- ½ cup granulated sugar
- ¼ cup light brown sugar
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- ½ teaspoon ground ginger
- ¼ teaspoon ground nutmeg
- Pinch of table salt (about 1/8 teaspoon)
Pecan crunch topping
- ½ cup unsalted butter, softened and cut into pieces
- ½ cup all-purpose flour
- ½ cup brown sugar, packed
- 1 teaspoon ground cinnamon
- 1½ cups chopped pecans
Serving additions
- Whipped cream
- Salted caramel sauce or vanilla ice cream
How to assemble and bake this pumpkin-pecan cake
- Preheat oven to 350°F. Grease a 9 x 13-inch baking dish with cooking spray.
- In a large bowl, whisk pumpkin puree with heavy cream, eggs, sugars, vanilla, spices, and salt until smooth.
- Pour the pumpkin mixture into the prepared pan. The mixture will be loose; that is expected.
- In a separate bowl, combine flour, brown sugar, and cinnamon. Cut the softened butter into the dry ingredients with a fork until crumbly.
- Scatter one-third of the crumb mixture evenly over the pumpkin layer.
- Stir the chopped pecans into the remaining crumb mix. Sprinkle that over the top.
- Bake 45–55 minutes, until the center is set but still slightly jiggly. A toothpick should come out mostly clean.
- Cool to room temperature on a wire rack. Serve with whipped cream or a drizzle of salted caramel.
Timing, yield, and practical tips for a perfect bake
- Prep time: about 10 minutes.
- Cook time: 45–55 minutes, depending on oven and pan.
- Total time: roughly 60 minutes including cool down.
- Yield: serves about 12–16 slices.
Smart tips
- Use canned pumpkin puree for consistent texture.
- Don’t overmix the pumpkin batter; stir until combined.
- If the topping browns too fast, tent the pan with foil for the last 10 minutes.
- Make it a day ahead; flavors deepen and slicing is easier when chilled slightly.
- Swap toasted walnuts for pecans if desired.
Make-ahead storage, reheating, and variations
- Refrigerate leftovers in an airtight container for up to 4 days.
- Freeze individual slices wrapped in foil for up to 2 months.
- Warm slices in a 325°F oven for 10–12 minutes before serving.
- For a lighter version, substitute half-and-half for the heavy cream.
- Add a pinch of cloves or allspice for extra autumn spice.
