Instructions
- Prep the pan:
- Preheat the oven to 350°F (175°C). Grease and line a 9x13-inch (23x33 cm) sheet pan with parchment paper.
- Mix dry ingredients:
- In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
- Mix wet ingredients:
- In a separate bowl, whisk together soda, melted butter, eggs, and vanilla extract until well combined.
- Combine batters:
- Add the wet ingredients to the dry ingredients and mix gently until just combined. Do not overmix.
- Bake the cake:
- Pour the batter into the prepared pan and smooth the top. Bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean. Cool the cake completely in the pan on a wire rack.
- Make the frosting:
- Beat the softened butter until creamy, then gradually add powdered sugar. Mix in soda, heavy cream, vanilla, and salt. Beat until light and fluffy.
- Frost the cake:
- Spread the frosting evenly over the cooled cake. Garnish with maraschino cherries, sprinkles, and dollops of whipped cream, if desired. Slice and serve.

Common Questions About Recipes
- → Which type of soda is best to use?
Cream soda or root beer work well, providing sweet and distinctive float flavors.

Butter gives rich flavor and moist texture. Oil can be used, but the taste will differ.
- → Is the soda supposed to be flat?
Yes, let the soda go flat before mixing. This prevents excess bubbles in the batter.
- → How do I make the frosting fluffy?
Beat softened butter first, then add sugar and liquids gradually. Whip until light and creamy.

Keep sheet cake covered at room temperature for up to two days to maintain freshness.
