Pumpkin Smoothie

This pumpkin smoothie was one of my first experiments with pumpkin purée TEN years ago. I had a little bit of pumpkin leftover from another recipe and thought, “Hey, can I put this in my smoothie?” Yes, Beth, yes you can. And it will taste like a pumpkin pie milkshake. Forget the PSL, this is the pumpkin drink I want to be drinking. Especially if you live in the south and it’s still 80 degrees outside in October. :P

What’s in A Pumpkin Smoothie?

The ingredients for this smoothie are incredibly simple: pumpkin purée, frozen banana, ground flaxseed, pumpkin pie spice, milk, sweetener of choice, and vanilla extract. The frozen banana gives the smoothie an ice-cream-like texture and the ground flaxseed almost makes the smoothie taste like a graham cracker crust has been blended right into the drink. It’s magical!

Use the Milk of Your Choice

I used whole milk because it is the richest and creamiest, but you can use any non-dairy milk substitute in its place. If your non-dairy milk is already sweetened or vanilla flavored, you can reduce the added sweetener and or skip the vanilla extract listed in the recipe below.

Sweeten to Taste

The best part about making your own smoothie is that you can add as much or as little sugar as you want, and use whatever kind of sugar or sugar substitute that you like. I used brown sugar because it has a rich flavor that makes the smoothie even more pie-like, but you can use honey, white sugar, agave, stevia, or whatever you like. The frozen banana does offer some sweetness on its own, but I found the little extra sweetness really made a difference.

Pumpkin Pie Spice

If you don’t have store-bought pumpkin pie spice, you can use my recipe for homemade pumpkin pie spice here, or just sub in ¼ tsp cinnamon if needed. It’s such a small amount in the smoothie that it won’t make or break the smoothie.
