Bake at 300 degrees F for 60-70 minutes until a toothpick inserted into the middle of the cake comes out clean. Remove the cake from the oven and transfer it to a wire rack to cool completely (20-30 minutes).
While the cake is cooling, prepare the glaze. Whisk together the confectioner’s sugar, vanilla extract and milk. Gradually add the milk to the mixture until the glaze is the consistency that you prefer.
Once the cake has cooled completely, invert the cake onto your favorite cake pan. Drizzle the glaze on top.
