finally, add the buttermilk and mix until combined and smooth. this is the brownie layer.
pour the brownie mixture into the skillet and smooth out with a spatula. top with the pumpkin layer. using a knife, swirl the pumpkin mixture into the brownie mixture to get a pretty swirl effect. i went through the mixture a few times with my knife.
let cool for about 20 minutes, cut a pie sized piece and top with warm caramel sauce and a scoop of vanilla ice cream!
what a perfect little dessert. thanks for the recipe.
