BEST EVER Pumpkin Butter Cake is easy to make, luxurious, rich and perfectly moist. It is absolutely divine covered in a boozy and sweet rum glaze.
In a medium bowl combine powdered sugar and rum, mix with a whisk or spoon until fully blended and without lumps. Mixture should be a stiff glaze, but still pourable. If the glaze is too thick, thin with a bit of rum or milk. Using a spoon, drizzle the glaze all over the cooled cake. Let the cake sit until the glaze has hardened.
