Chef Tips from the Video
- Use pumpkin puree that is 100 % pure pumpkin, not pumpkin pie filling, for a less sweet base.
- Add a pinch of cinnamon or nutmeg to the batter for extra warmth.
- For a shinier finish, lightly brush the top with a thin glaze made from 1 tbsp milk and 1 tbsp powdered sugar.
Troubleshooting
Cake is dense or sinks in the middle.
Do not over‑mix the batter and ensure the oven is fully pre‑heated. Also, check that baking powder is fresh.
Whipped cream is too runny.
Make sure the cream and bowl are well chilled; add a tablespoon of powdered sugar and whip a little longer.
Jam slides off the frosting.
Pat the cake surface dry with a paper towel before spreading jam, and apply a thin layer of whipped cream as a “glue” before the jam.
Storage
Refrigerator: Store in an airtight container for up to 3 days.
Freezer: Wrap tightly in plastic wrap and foil; freeze for up to 1 month.
Room temperature: Not recommended; cake may soften and jam can spoil.
Make-Ahead Tips
- Bake the cake layers up to 2 days ahead and store wrapped in the fridge.
- Whipped cream frosting can be made 24 hours ahead; keep chilled.
- Jam layers can be prepared and refrigerated separately.
