This recipe came from my friend Laura. I made only one minor change to the frosting. The original recipe uses orange juice instead of vanilla oat milk but I liked the sweeter taste with the vanilla oat milk. Thank you Laura for sharing this recipe!
Cream together butter, sugar, pumpkin, egg and vanilla.
Mix together flour, baking soda, baking powder, salt, and cinnamon.
Combine wet and dry ingredients. Drop by heaping teaspoonful onto greased baking sheet (grease between batches). Bake at 350 degrees for 10-15 minutes. Cookies will look cake like and have slightly browned edges. Cool slightly before moving to cooling rack.
To make frosting combine melted butter, vanilla oat milk, and powdered sugar. Add lemon juice 1 tablespoon at a time until desired taste and consistency (3-4 tablespoons total). Frost cookies while still hot.
