There have been a few rainy days this season so I’ve been doing some baking projects with my daughter here and there. One of them has been this root beer float cake-in-a- jar. We found it hilariously fun because you really add root beer to cake mix (mind blown!) and bake it up in jars. Then we added a thick topping of whipped vanilla frosting to make it look like an actual mug of root beer. So fun!
I’ll admit I was totally skeptical that this would work and was really surprised when it actually did. The cake honestly had a mild root beer flavor. Since I used vanilla cake mix, it kind of tasted like a root beer float. Wild! My daughter asked to have a scoop of ice cream on top of her cake, but I just ate mine plain. It was plenty rich enough and tasted so good I didn’t want to dilute it with ice cream or any other add-on. This super fun summer project would be ideal for a rainy day, or heck, just a day you want to hang out in the kitchen!
Root Beer Float Cake-in-a-Jar
1 box white cake mix
1 1/4 cups root beer
1/3 cup vegetable oil
3 egg whites
1 container whipped vanilla frosting
1. Preheat the oven to 350° F. Lightly oil the inside of 6 half-pint glass jars.
2. Whisk the cake mix, root beer, vegetable oil, and egg whites until smooth and light. Divide the batter evenly amongst the jars so they are each about 3/4 full. Place the jars on a baking sheet and bake for 25 to 30 minutes, or until the cake is done and a tester inserted into the middle comes out clean.
3. Carefully move the hot jars to a wire rack to cool. When they are at room temperature, top each one with a thick layer of vanilla frosting. Serve!
