Why We Love It

Is it just me, or is pumpkin season creeping up earlier and earlier each year? I swear I saw pumpkin lattes and donuts in late June/early July. Now, as I write this, it's the middle of September and you can just forget it: pumpkin everything is practically everywhere.

Apple season is definitely getting eclipsed by pumpkins. And although I'm still making my apple faves like Baked Apple Crisp and Apple Cinnamon Kuchen, I must admit there is one pumpkin recipe that I do sneak in fairly early into my fall baking rotation.

It's this delicious Pumpkin Spice Crumble. Just thinking about it makes me want to stop what I'm doing, get into the kitchen and make one right now! My family loves this recipe so much, we're seriously considering replacing a pumpkin pie at Thanksgiving with this tasty dessert.

That might be unheard of and downright forbidden in some houses, but I'm pretty sure I could get away with it here. Pumpkin Spice Crumble is always a crowd pleaser. It's rich and packed full of pumpkin pie flavor, yet easier to make, serve and eat than a pie.

That's because this delicious dessert is a box cake hack. Rather than a crust, we use a yellow cake mix, butter and an egg to create a rich bottom layer. This then gets topped with all the best parts of a pumpkin pie (including milk, sugar and spice). And the trifecta?--that buttery, spiced crumble on top!

Pumpkin pie lovers enjoy Pumpkin Spice Crumble because it tastes like their favorite dessert--only richer. I like making it because it tastes great and is way easier to serve than a pie. It feeds a crowd and tastes incredible!

So yeah, it just might become my new Thanksgiving go-to. Sorry, pumpkin pie. I think we might be on the outs.

Why You'll Love It

No crust, no hassle: Delicious homemade pumpkin pie taste without the added task of dealing with a crust.

Bakes in 45: This is ready in less time than a pie and can be served shortly after coming out of the oven.

Feeds a crowd: Because it bakes in a 13x9 pan, you can easily serve 12 people with this one!

Tastes great served warm or cold: Want to make it ahead of time? No problem! Simply reheat it or serve it cold. It tastes great either way!
