When it comes to fall recipes, these pumpkin crumb muffins are a must-make!
They’re easy to make, pull double duty as breakfast and dessert, and just like my New York crumb cake, make an excellent companion to a cup of coffee.
Crumb Ingredients
All ingredients for this recipe are shown in the pic below and special notes are made in this bulleted list to assist you.

- Flour. All-purpose flour is used for the crumb topping.
- Butter. Use unsalted butter for the topping.
- Spices. I’m using a combo of cinnamon and pumpkin pie spice, which is typically a blend of nutmeg, allspice, cloves, ginger, and cinnamon. These same spices are also included in the muffin ingredients.

Muffin Ingredients
All ingredients for this recipe are shown in the pic below and special notes are made in this bulleted list to assist you.

- Pumpkin. Be sure to use pumpkin puree and not pumpkin pie filling for these pumpkin crumb cake muffins.
- Oil. Use a neutral oil such as vegetable, canola, or avocado oil.
- Buttermilk. If you don’t have buttermilk you can use regular milk with a little white vinegar, about 1 tablespoon per cup of milk is the rule of thumb.

How to make it
- Melt 1/2 cup (113g) of butter and allow to cool slightly. In a large bowl combine 1 1/2 cups (195g) of all-purpose flour, 1/3 cup packed (66g) of dark brown sugar, 2 tablespoons (26g) of granulated sugar, 1 teaspoon (3g) of ground cinnamon, 1 teaspoon (3g) of pumpkin pie spice, and a pinch of salt. Pour the melted butter into the bowl.
- Use your hands to toss the butter and dry ingredients together, forming large crumbs. Be careful to not overmix! If the crumbs are too small, you can squeeze together some smaller crumbs to make larger ones. If the crumbs are too wet, add 1 teaspoon of flour at a time and gently mix with your hands to form larger crumbs. Set the mixture aside.

- Preheat the oven to 350f and set the rack to the middle level. Grease or place jumbo muffin liners in a jumbo muffin pan. In a large bowl whisk together 2 1/2 cups (325g) of all-purpose flour, 1 teaspoon of baking soda, 1/2 teaspoon of baking powder, 1 tablespoon of ground cinnamon, 1 teaspoon of pumpkin pie spice, and 1/2 teaspoon of fine sea salt. In another large bowl, whisk together 1 cup (200g) of granulated sugar, 1/4 cup packed (50g) of dark brown sugar, 1/2 cup (120g) vegetable oil, 2 large room temperature eggs, 1 room temperature egg yolk, 1/2 cup (115g) buttermilk, 2 teaspoons of vanilla extract, and 1 1/4 cups (300g) of pumpkin puree. Add the wet ingredients to the dry ingredients and fold gently until no specks of flour appear. Be careful not to overmix.
- Divide the batter into 10-12 prepared jumbo muffin pan(s) (the batter should come about 3/4 high) and bake for 10 minutes.
- Remove from the oven and allow the muffins to sit for 3-5 minutes.
- After 3-5 minutes distribute the crumb mixture evenly on top of the muffins and return to the oven.

- Bake for an additional 20-25 minutes or until a toothpick inserted in the center comes out clean.
- Place the pumpkin crumb muffins on a wire rack to cool completely. Once cool, prepare the icing by whisking together 1 1/4 cups (140g) of powdered sugar, 1 teaspoon of vanilla extract, and 3 tablespoons of milk. Use a spoon to drizzle the icing on top of each muffin. Enjoy!
Top tips
- Muffin size. This recipe is written for and makes ~10 jumbo muffins. For standard muffins (approximately 30), you will need to reduce the baking time to roughly 14-20 minutes total.
- Don’t overmix. Similar to quick breads, like banana bread, the batter for these pumpkin crumb muffins should not be overmixed as it can lead to tough muffins.
- Use a kitchen scale. When it comes to baking and bread or pizza making, I strongly recommend using a kitchen scale. It’s the only way to ensure consistent results and accurate measurements.
