Preheat the oven to 350 degrees F. Line a baking sheet with a Silpat or parchment paper and set aside.
In a medium bowl, whisk together the flour, baking soda, cinnamon, nutmeg, ginger, allspice, and salt. Set aside.
In the bowl of a stand mixer, add the butter and sugars. Beat until creamy and smooth, about 3 minutes. Add the pumpkin and Biscoff spread and mix until combined. Add the egg and vanilla extract and beat until smooth.
Reduce the mixer speed to low and slowly add the dry ingredients, beating only until blended. Stir in the oats.
Form the cookie dough into rounded tablespoons and place them 2 inches apart on the baking sheet. Bake for 10-12 minutes or until cookies are golden and just firm around the edges. Let the cookies cool on the baking sheet for 5 minutes and then remove with a spatula onto a cooling rack.
Note-you can also use Trader Joe's Cookie Spread in this recipe. I prefer Biscoff Spread though:)
