This Ultimate Root Beer Float Layer Cake brings the classic soda shop favorite to life in cake form, featuring moist, root beer–infused chocolate layers paired with a light, fluffy root beer–flavored whipped topping. The cake delivers the airy, creamy root beer float experience in every bite—a perfect treat for birthdays, cookouts, or nostalgia seekers. Optimized for search-friendly terms like "root beer float cake," "root beer layer cake," and "southern root beer cake," this dessert blends retro charm with modern simplicity.
Based on a trusted Taste of Home recipe—where root beer is incorporated into both cake and frosting—this version remains faithful to the beloved float flavor while elevating the presentation with layered structure.
Ingredients
-
1 package white cake mix
-
1¾ cups cold root beer, divided
-
¼ cup canola oil
-
2 large eggs
-
1 envelope whipped topping mix (Dream Whip)
Directions
Preheat your oven to 350°F (175°C).
In a large bowl, combine the cake mix, 1¼ cups of cold root beer, oil, and eggs; beat on low speed for 2 minutes—alternatively stir by hand for 3 minutes.
Pour the batter into a greased 13×9‑inch pan and bake until a toothpick comes out clean, about 30–35 minutes. Let the cake cool completely on a wire rack.
While the cake cools, whisk together the Dream Whip topping mix and the remaining root beer until soft peaks form.
Frost the cooled cake generously with this root beer–flavored whipped topping. Refrigerate until ready to serve.
Recipe Note
10 Frequently Asked Questions
Can I use homemade cake instead of a mix?
Yes! A scratch cake with root beer in the batter or buttercream works beautifully—see Cake by Courtney’s layered version.
Do I have to use Dream Whip?
It’s easy and gives light texture, but you can substitute stabilized whipped cream with root beer flavor.
Can I use diet root beer?
Regular is recommended for best flavor and texture, especially in the Dream Whip frosting.
Can I turn this into a layer cake?
Definitely—bake in round pans and layer with root beer buttercream or whipped topping, as shown in Cake by Courtney’s version.
How far ahead can I make it?
Bake and frost up to a day ahead. Store in the fridge, and bring to cool room temperature before serving for best texture.
Can I add crushed root beer candies?
Yes—sprinkle over the frosting for crunch and garnish, like Betty Crocker suggests.
Is this recipe kid-friendly?
Absolutely—nostalgic flavor and fluffy frosting make it a favorite among kids and adults alike.
Can I reduce sugar?
The cake mix and Dream Whip are premade, so reduction may affect structure—try lighter toppings instead.
What’s the best root beer to use?
A flavorful, not too sweet brand works well. For purer flavor, frost with extract-enhanced whipped topping.
How should leftovers be stored?
Keep covered in the refrigerator for up to 3 days. Serve cold or slightly softened.
