In a medium sized saucepan over medium heat, warm the heavy cream (or milk or half and half) and butter together on the stove. You’ll want the cream to become warm enough to melt the butter, but not so hot that it scalds or boils. When the butter is melted, remove from the heat and set aside to cool.
½ cup heavy cream, 6 tablespoons unsalted butter
In a large mixing bowl, or the bowl of a stand mixer, whisk together the pumpkin puree, egg, sugar and pumpkin pie spice.
¾ cup pumpkin puree, 1 large egg, ½ cup granulated sugar, 2 teaspoons pumpkin pie spice
Whisk the melted cream and butter in until fully combined.
In another mixing bowl, whisk together the flour, instant yeast and salt, then add it to the pumpkin mixture about ½ cup at a time, scraping down the sides and bottom of the bowl as needed.
3 cups all-purpose flour, 2¼ teaspoons instant yeast, ¼ teaspoon fine sea salt
When the mixture has formed a dough ball that is pulling away from the sides of the bowl, cover it with a clean dish towel or plastic wrap and set aside to rise for about 45 minutes to 1 hour.
