The cake has four thick orange-brown sponge layers, each separated by creamy off-white frosting with small bits of nuts visible inside. The top layer is fully covered with the same smooth frosting and sprinkled generously with chopped pecans. The background and surface are changed to a white marbled texture, soft and out of focus, highlighting the cake's rich colors and textures. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 2/3 cups (425g) fresh pumpkin puree
15 oz / 425g canned pure pumpkin (1 can)
4 large eggs (50 – 55 g/2 oz each), at room temperature
1 3/4 cups white sugar (or caster/superfine sugar)
1 cup vegetable or canola oil (or other neutral flavored oil)
2 cups plain/all-purpose flour
3 tsp baking powder
2 tsp cinnamon powder
1 tsp cooking/kosher salt
500g / 16oz cream cheese (block type), at room temperature (2 blocks)
250g / 18 tbsp unsalted butter, softened (US: 2 sticks + 2 tbsp)
3 cups (360g) soft icing sugar / powdered sugar, sifted
1 1/2 tsp vanilla extract
1/2 tsp cooking/kosher salt
1 cup pecans
2/3 cup white sugar (superfine/caster sugar works too)
1/4 tsp cooking/kosher salt

Instructions

Step 1: Preheat the oven to 180°C/350°F (160°C fan-forced). Lightly grease two 38 × 25 cm (10 x 15″) baking trays about 2.5 cm (1″) deep with oil or butter, then line with baking paper.
Step 2: In a large bowl, whisk together the fresh and canned pumpkin with the eggs, sugar, and oil until combined. In a separate bowl, mix the flour, baking powder, cinnamon, and salt. Add the dry ingredients to the wet and whisk until smooth.
Step 3: Divide the batter evenly between the two trays (about 735g each). Spread it out to the edges using a spatula, then tap the trays firmly on the counter to level the batter.
Step 4: Bake for 15 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes, then invert the cakes onto cooling racks. Cool completely for at least 1 hour or refrigerate overnight.
Step 5: Once cooled, invert a cake layer onto a cutting board and cut in half lengthwise. Trim edges if needed for even layers. Cover each piece with a trimmed sheet of baking paper to make handling easier.
Step 6: To make the toffee pecan crumble, preheat oven to 180°C/350°F (160°C fan-forced). Spread pecans on a tray and toast for 10 minutes. Let cool for 5 minutes.
Step 7: In a saucepan over medium-low heat, spread the sugar and let it melt slowly without stirring. Once edges melt into syrup and sugar turns pale golden, remove from heat. Quickly stir in pecans and salt, coating them evenly.
Step 8: Spread the coated pecans on baking paper to cool and harden for about an hour. Break into chunks and chop into small pieces or dust for garnish. Set aside.
Step 9: For the cream cheese frosting, beat cream cheese and butter together on medium-high speed until smooth and fluffy, about 2 minutes.
Step 10: Gradually add sifted icing sugar in three batches, starting the mixer on low each time to avoid a sugar cloud. Scrape sides as needed. Add vanilla and salt, then beat on high for 1 minute until fluffy.
Step 11: Assemble the cake on your serving platter. Spread one-fifth of the frosting on the first cake layer, sprinkle about 1/4 cup of pecan crumble, then add the next layer. Repeat with frosting and pecan crumble for all layers.
Step 12: Frost the top and sides with the remaining frosting and sprinkle with the remaining pecan crumble. Refrigerate for at least 1 hour to set before slicing and serving.

Tips & Variations

Use fresh pumpkin puree if possible for the best flavor, but canned pumpkin works well in a pinch.
Adjust the cinnamon amount to your taste or add a pinch of nutmeg and cloves for a spicier kick.
For a nut-free version, omit pecans and add toasted coconut flakes or seeds instead.
If the frosting thickens after refrigeration, let it come to room temperature and beat it briefly to regain fluffiness.

Storage

Store the cake covered in the refrigerator for up to 4 days. Bring to room temperature before serving for the best texture and flavor. The cake can also be frozen, wrapped tightly, for up to 1 month; thaw overnight in the fridge and re-fluff the frosting if needed.

FAQs

Can I make this cake gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free blend that measures cup-for-cup, but make sure it contains xanthan gum or another binder for best results.

How do I prevent the cake layers from drying out?

Be careful not to overbake; check the cake with a toothpick at 15 minutes. Also, fully cool the layers before wrapping or assembling to keep moisture locked in.
