Baking Tips & Tricks

  • For the perfect crumb topping, mix it until you get those pea-sized crumbs, then sprinkle it all over your batter for that amazing crunchy contrast.
  • Mix the batter just enough to combine the ingredients—overmixing can make the cake dense, and we want it soft and fluffy like a warm hug for your taste buds.
  • Rotate your pan halfway through baking to make sure it cooks evenly. This trick ensures every slice of your pumpkin spice crumb cake is baked to perfection.
  • Don’t skip the toothpick test! Stick it in the center, and if it comes out clean, your cozy fall dessert is ready to enjoy.

How to Store Leftovers

After enjoying some cozy homemade pumpkin spice crumb cake, you’ll want to keep those leftovers fresh. For a few days, just wrap it in plastic or pop it into an airtight container, and it’ll stay moist at room temp.

Want to save some for later? Freeze slices by wrapping them in plastic and foil—they’ll last up to three months. Just thaw when you’re craving that fresh-out-of-the-oven taste.

Recipe Variations

  • Tossing in some nuts or chocolate chips into the crumb topping adds a fun crunch and extra sweetness that pairs perfectly with the pumpkin spice.
  • Swirl in some cream cheese into the batter for an extra moist cake with a tangy twist that balances all the sweet, spicy flavors.
  • Going gluten-free or vegan? No problem! Swap in gluten-free flour and plant-based ingredients, and you’ll still have a cozy, delicious dessert everyone can enjoy.
