Step 1

Preheat the oven to 350 degrees Fahrenheit. Grease the bottom of a 10-inch bundt pan with butter or oil and lightly coat with flour.

Step 2

In a medium bowl, whisk together the cake mix, 12 ounces of root beer, oil, and eggs until the mixture is smooth and well-combined.

Step 3

Pour the batter into the greased bundt pan. Bake for 35 to 40 minutes. To check for doneness, insert a toothpick into the center of the cake - if it comes out clean, it’s done baking.

Step 4

Flip the pan onto a wire rack and let the cake cool completely while in the pan.

Step 5

Using a knife or skewer, poke holes into the cake, with a 2-inch space in between.

Step 6

Remove the cake from the pan. Loosen the sides with a knife or flat spatula if needed.

Step 7

Drizzle 3 tablespoons of root beer over the poked cake.

Step 8

If making a root beer glaze, stir together powdered sugar and 3 tablespoons of root beer until smooth. Spread glaze over the cake.

Step 9

Slice, serve, and enjoy!
