Preheat oven to 350 degrees. Line a baking sheet with parchment paper or silicone baking mat and set aside.
In a large bowl, stir butter, oil, pumpkin, sugars, vanilla, and eggs together until incorporated and smooth. Slowly mix in all dry ingredients until completely incorporated.
Scoop onto prepared baking sheet using 1.5 TBSP scoop and flatten to 1/2in thick using the bottom of a glass. If the dough is sticking to the glass, press the bottom the glass in granulated sugar before flattening. Bake 8-9min.
While cookies bake, stir all ingredients together for glaze until smooth.
Once cookies are finished baking, cool 3min on baking sheet before transferring to a cooling rack. Spread 1.5 TSP glaze over each warm cookie. Let glaze harden 2-3hrs before serving (or eat them warm with runny sticky glaze).
