1 cup pumpkin puree
1 cup all-purpose flour
1/2 cup granulated sugar
1/2 cup brown sugar
2 large eggs
1/2 cup vegetable oil
1 tsp baking powder
1 tsp baking soda
1 tsp ground cinnamon
1/2 tsp salt
Preheat the oven to 350°F (175°C).
Prepare the muffin tin by lining it with paper liners or greasing it with non-stick spray.
In a large bowl, combine flour, baking powder, baking soda, cinnamon, and salt. Whisk them together.
In another bowl, whisk together the pumpkin puree, granulated sugar, brown sugar, eggs, and oil until well combined.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined.
In a small bowl, mix together flour, sugar, and cold butter for the crumb topping until crumbly.
Scoop the muffin batter into the prepared muffin tin, filling each cup about 2/3 full.
Generously sprinkle the crumb topping over each muffin.
Bake in the preheated oven for 18-22 minutes, or until a toothpick comes out clean.
Allow to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
