Preheat & Prep Pan: Preheat your oven to 350°F. Grease a 9×5-inch loaf pan and set aside.
Mix Wet Ingredients: In a large mixing bowl, combine ½ cup melted butter, 1 cup pumpkin, 1 cup sugar, and 1 box (3.4 oz) dry butterscotch pudding mix. Stir until smooth.
Add Eggs & Buttermilk: Beat in 2 eggs and ⅓ cup buttermilk until fully combined.
Add Dry Ingredients: Add 2 ½ cups flour, 1 ½ tsp pumpkin pie spice, ½ tsp cinnamon, 2 tsp baking powder, and 1 tsp baking soda. Stir gently until smooth and there are no dry pockets.
Bake: Pour the batter into the prepared loaf pan. Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
Cool & Drizzle: Let the bread cool completely in the pan. In a small microwave-safe bowl, melt ½ cup butterscotch chips with 1 tsp coconut oil. Drizzle the melted butterscotch over the cooled loaf.
