This pumpkin coffee cake is moist with a beautiful crumb and a delicious cinnamon crumb topping. It's a cozy breakfast loaded with rich fall spices - a perfect morning treat!
Put butter all crumb topping ingredients in a small bowl.
Use a fork, pastry cutter or your hands to cut the butter into the dry ingredients until the mixture forms large crumbs, set aside.

In a large bowl, whisk together pumpkin, melted butter, sour cream, whole milk, eggs and vanilla until mixture is smooth.

Notes
Ingredient Substitution Notes
Pumpkin Puree. canned or homemade pumpkin puree both work well.
Salted Butter. unsalted butter, coconut oil or ghee are all good substitutes.
Sour cream. I recommend full-fat sour cream for the richest taste and best texture, however low fat can be used, or plain Greek yogurt.
Whole milk. half and half, heavy cream and 2% milk are al good substitutions.
Granulated sugar. Organic cane sugar and white sugar are the best choices.
Light Brown Sugar. If you like a little bolder, molasses taste, use dark brown sugar.
All-purpose flour. I recommend using an unbleached, all-purpose flour. Bread flour and cake flour also work well. You can substitute up to half the flour with whole wheat pastry flour. Or, use all-purpose gluten-free baking flour to make it gluten-free.
