Ingredients & Equipment needed

  • Dry Ingredients: You’ll need all-purpose flour, pumpkin pie spice, baking soda, baking powder, and salt.
  • Wet Ingredients: You’ll need vegetable oil (or melted butter), granulated sugar, light brown sugar, eggs, vanilla extract, sourdough starter discard, pure pumpkin purée (not pumpkin pie filling), and whole milk.
  • Crumble Topping: You’ll need butter, light brown sugar, all-purpose flour, ground cinnamon, and chopped pecans. If you don't have any pecans on hand, walnuts can be used in place of them.
  • Pumpkin Pie Spice Sugar Filling: A simple mix of light brown sugar, all-purpose flour, and pumpkin pie spice.

Homemade Pumpkin Pie Spice

You can use your favorite store-bought pumpkin pie spice, but we highly recommend making your own. Our pumpkin pie spice recipe has the perfect balance of cinnamon, ginger, nutmeg, allspice, and cloves.

Let it cool completely before slicing, and enjoy!

How to Store

Once the sourdough pumpkin coffee cake has cooled completely, wrap the slices tightly in plastic wrap or place them in an airtight container.

Room Temperature: Keep the cake at room temperature for up to 2 days. It will stay soft and flavorful, making it perfect for a quick slice with your morning coffee.

Refrigerator: For longer storage, refrigerate the cake for up to 5 days. The texture will remain tender, but allowing it to sit at room temperature for a few minutes before serving helps it regain its soft, cake-like texture.

Freezer: You can also freeze the cake for up to 3 months. Slice it before freezing for easy portioning, then wrap each piece individually in plastic wrap, then in foil or a freezer-safe bag. Thaw at room temperature before serving.

    Amazing flavor and texture!! The pecans add the perfect extra crunch to the top. The batter is rather thick, so take your time spreading it in the pan. I’d suggest using a small offset spatula. Also, for the second layer of batter, drop it in dollops to help with spreading around. Make this!!!!!

    Hey there! I haven’t made this yet but am planning to this weekend! I was wondering if you could do an overnight ferment with it? If so, would you leave anything out of the batter until the next morning? Thanks!:)

    1. Hi Katie! We typically recommend leaving the leavening agents out and adding them back in right before you bake. Sometimes the fermentation process can weaken the leavening agent
