Preheat oven to 325 °F. Spray a 9×13 cake pan or an 8-cup bundt pan with nonstick baking spray and flour. In a large bowl, combine cake ingredients and fold together until combined.
Pour batter into prepared pan and bake for 35 to 50 minutes until golden brown. When a toothpick inserted into the center comes out clean or with just a few crumbs, the cake is done.
While the cake is in the oven, combine the glaze ingredients. Whisk to blend. Remove cake from oven. Whisk the glaze mixture again, and carefully spoon 1/2 of the glaze over the cake.
Let the cake cool in the bundt pan for 10 minutes. Loosen the edges of the cake and turn it out onto a serving plate. Slowly drizzle the remaining glaze over the top of the warm cake.
