Preheat oven to 350°F. Grease a bundt pan with cooking spray or butter.
Place all of the cake ingredients in a large bowl. Mix with a hand mixer for 3 minutes.
1 package yellow cake mix, 1 (3.4 oz) box instant vanilla pudding mix, ½ cup vegetable oil, 4 eggs, ¼ cup vodka, ¼ cup galliano, ¾ cup orange juice
Pour the batter into the greased bundt pan. Bake for 45–50 minutes, or until a toothpick comes out clean.
Let cake rest in the pan for 15 minutes after removing from the oven. Then, invert onto a wire rack.
In a medium bowl, whisk the glaze ingredients together until smooth. If it’s too thick to pour, add a splash more orange juice. Drizzle over the warm cake.
1 cup powdered sugar, 2 teaspoons vodka, 2 teaspoons galliano, 2 teaspoons orange juice
Let cool completely before serving.
Notes
How much alcohol is in this cake? There are 4.5 ounces of alcohol in this cake. That's the equivalent of three shots (1.5 ounces each). The cake serves 12, so that's a quarter of a shot per person (not much!). Where can I find Galliano? If your local grocery store doesn't have it, try a larger liquor store. I found it at Binny's in Chicago.Storage: store any leftovers in an airtight container for up to a week. You can also freeze this cake.Kate's note: I found recipes for Harvey Wallbanger Cake in various spiral-bound cookbooks ranging from 1965–1978. This was the most common recipe for it.
