In a large bowl, whisk together the pumpkin puree, granulated sugar, brown sugar, eggs, vegetable oil, and milk. You want it smooth and creamy, no sugar lumps! I usually go for about a minute, really getting it light and airy. It should smell sweet and earthy already, a little preview of the deliciousness to come.

In a separate medium bowl, whisk together the flour, pumpkin pie spice, baking soda, baking powder, and salt. Make sure it's all evenly distributed. This is where I always double-check I didn't forget the baking powder – oops, done that before! You want everything incorporated so your muffins rise beautifully.

Gently add the dry ingredients to the wet ingredients. Mix just until *just* combined. Seriously, stop mixing the moment you don't see any more streaks of flour. Overmixing is the enemy of tender muffins; you'll end up with tough, chewy muffins, and we want light, fluffy ones! A few small lumps are totally fine, even desirable.

In a small bowl, combine the flour, brown sugar, and cinnamon for the topping. Then, using your fingertips or a pastry blender, cut in the cold butter until you have a coarse, crumbly mixture. Some pieces will be pea-sized, others a bit smaller. This is the fun part, getting your hands in there! This crumbly goodness is what makes these Pumpkin Crumb Cake Muffins truly special.

Line a 12-cup muffin tin with paper liners. Fill each liner about two-thirds full with the muffin batter. Don't overfill, or you'll have muffin tops that spill over and merge into one giant muffin monster – I've been there! Then, generously sprinkle the crumb topping over each muffin. Don't be shy!

Pop the muffin tin into a preheated oven at 400°F (200°C) for 5 minutes, then reduce the temperature to 375°F (190°C) and bake for another 15-20 minutes, or until a toothpick inserted into the center comes out clean. The tops should be golden and the kitchen will smell absolutely divine. Let them cool slightly in the pan before transferring to a wire rack. These warm muffins are heavenly!
