Method
Bake the pumpkin spice cake
- Preheat the oven to the temperature listed on the spice cake mix box and grease a 9x13 baking dish.
- Make the spice cake batter per box instructions, then stir in pumpkin puree and pumpkin pie spice until smooth.
- Bake in the 9x13 pan for 30 minutes, or until a toothpick inserted in the center comes out clean and the top springs back when lightly pressed.
Soak with milk and caramel
- While the cake is hot, use the handle of a wooden spoon to poke holes all over the surface, spacing them evenly so the soak reaches everywhere.
- Pour the sweetened condensed milk over the hot cake, letting it flow into and down through the holes.
- Pour the caramel sauce over the top evenly.
- Refrigerate for 60 minutes until the caramel has started to absorb and the surface looks set.
Finish with whipped topping
- Spread the whipped topping over the chilled cake in an even layer.
- Scatter the toffee bits over the whipped topping, then drizzle with extra caramel sauce.
- Refrigerate at least 60 more minutes before serving so the layers firm up and slice cleanly.
Notes
For the best soak, wait until the cake is hot from the oven before poking holes and pouring the condensed milk—this helps everything absorb without pooling. Refrigerate leftovers covered for up to 4 days; freeze is not recommended because whipped topping texture can break down. For a lighter option, use sugar-free caramel sauce and a reduced-sugar whipped topping if desired.
