Ingredients

• 2 cups All-purpose flour
• 1.5 cups Granulated sugar
• 2 teaspoons Baking powder
• 1 teaspoon Baking soda
• 0.5 teaspoon Salt
• 0.5 cup Unsalted butter, softened
• 1.5 cups Root beer (not diet)
• 2 teaspoons Vanilla extract
• 2 large Eggs
• 0.25 cup Cream soda
• 1.5 cups Powdered sugar
• 3 tablespoons Heavy cream
• 2 scoops Vanilla ice cream

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and lightly flour a 9x13-inch baking pan and set aside.

Step 2

In a large mixing bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt.

Step 3

Add the softened butter to the dry ingredients. Use a hand or stand mixer on medium speed to blend until the mixture becomes coarse and crumbly.

Step 4

Slowly pour in the root beer and beat until the batter becomes smooth and well combined.

Step 5

Add the vanilla extract and eggs. Beat for about 1-2 minutes until fully incorporated.

Step 6

Pour the batter into the prepared baking pan and smooth the top with a spatula.

Step 7

Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Step 8

While the cake bakes, prepare the glaze by combining cream soda and powdered sugar in a small bowl. Mix until smooth and thickened. Add heavy cream and stir until you achieve a glossy consistency.

Step 9

Remove the cake from the oven and allow it to cool for 10-15 minutes.

Step 10

Drizzle the cream soda glaze evenly over the cake while it’s still warm.

Step 11

Serve slices of cake warm or at room temperature, topped with a dollop of vanilla ice cream for that classic root beer float vibe.

Step 12

Refrigerate leftovers in an airtight container for up to 3 days.
