Pumpkin Spice Lava Cake
Warm pumpkin spice cake with a molten center. Autumn in a crock pot.

Pumpkin spice has become a punchline, but the actual combination — cinnamon, ginger, nutmeg, clove and allspice against sweet squash — has been a fixture of American baking since long before it was a coffee flavor.
This is the molten cake structure applied to it. Batter in, hot water over the top, no stirring. The pumpkin makes it denser and moister than the chocolate versions, and the spice comes through warm rather than sharp.
One thing that trips people up: buy pumpkin purée, not pumpkin pie filling. Pie filling is already sweetened and spiced, and using it here makes something cloying.
Why you'll love it
Autumn in a bowl.
The whole house smells like it for two hours.

The pumpkin keeps it soft and dense.
Feeds eight for a holiday table.
An easy dessert on a day when the oven is full.

On Thanksgiving that's worth more than the dessert itself.

Done when
Edges set; center soft. Pumpkin holds more moisture, so give it the full rest.

Toppings & mix-ins
Whipped cream and a dusting of cinnamon is the simplest finish and hard to beat.
Before anything goes in the pot
- 1
Whisk the batter in a bowl, not in the crock
Lumps mixed in the pot stay lumps. A bowl and a whisk take one minute and the difference is visible in the finished cake.
These happen outside the crock pot, before it's switched on.
Tonight's Plan
- 1
Grease the crock pot or drop in a liner.
This batter sticks.
- 2
Whisk the packet, pumpkin, eggs, milk and melted butter together until smooth.
In a bowl. Pumpkin needs proper whisking to blend evenly.
- 3
Pour the batter into the crock pot and spread it flat.
Even layer.
- 4
Pour the hot water gently over the top and do not stir.
Same rule as every molten cake.
Right before you serve
Finishing touches
Turn it off and let it stand 15–20 minutes with the lid off.
Pumpkin cake needs slightly longer to set than chocolate.
Spoon from the pot, scooping sauce from the bottom over each serving.
Dig deep.
Stirring
Do not stir once the lid is on
Cakes, cobblers and puddings set in layers. Stirring collapses the separation between the cake and the sauce underneath, and you end up with one uniform wet layer instead of two good ones.
Swaps and add-ins
Add pecans.
Half a cup over the batter before the water.
Make it a pumpkin cheesecake version.
Dollop four ounces of softened cream cheese on the batter before the water.
Add chocolate chips.
Half a cup. Pumpkin and chocolate is underrated.
Use maple instead of some sugar.
Two tablespoons of maple syrup in the batter.
Tips for success
- Purée, not pie filling. Pie filling is pre-sweetened and pre-spiced. Using it makes the dessert cloying and throws off the balance.
- Do not stir after the water. Same rule as every molten cake in this book.
- It needs a little longer to set. Fifteen to twenty minutes resting, versus fifteen for the chocolate versions.
- Drop in a liner before anything else. Smooth it against the sides and fold the edges over the rim. When you're done, lift it out and throw it away — the crock never needs scrubbing.
Finish it right
Whipped cream and a dusting of cinnamon.
The simplest finish and genuinely the best one for this cake.
Toasted pecans.
Crunch against a very soft dessert.
A drizzle of caramel.
Pumpkin and caramel is a natural pairing.
