A fizzy, fluffy cake bursting with strawberry soda flavor and sweet candy charm!
This is a fun, easy strawberry sheet cake made with soda, jello, and a fluffy marshmallow frosting. It’s got a pink and green candy shop look and comes together with a box mix and a few simple add-ins. It has all the fun of a retro candy counter and the charm of a vintage soda fountain—sweet, nostalgic flavor.
FAQ
Can I use a different soda flavor?
Absolutely! Cherry soda or even pink lemonade soda would work beautifully. Just be sure to adjust the extract to match if you’re swapping out strawberry.
What’s the best way to store this cake?
Keep it covered in the fridge for up to 3 days. Let it sit out at room temp for 20–30 minutes before serving so the frosting softens a bit.
Do I need to pipe the frosting like the photo?
Not at all! You can keep it simple with just one frosting color, spread it on with a spatula, or swirl it with a spoon. But if you want that wow factor, the criss-cross pink and green combo really pops!
What candies work best on top?
Any strawberry-flavored candies work great—sour gummies, Jolly Ranchers, strawberry marshmallows, or even chewy pink taffy pieces.
Sprinkle of Fun
Bring back the charm of vintage soda fountains and drive-in theaters with a strawberry-themed movie night that’s straight out of the ’50s. Think: checkerboard napkins, pink paper plates, and retro music playing in the background.
Set the mood with classic flicks like Bye Bye Birdie, Grease, Beach Blanket Bingo, or Hairspray (the original or the musical—your call). Serve this fizzy pink sheet cake alongside strawberry soda floats in tall glasses with whipped cream and striped straws.
Pass out paper menus with “concession stand” snack options (like licorice laces, popcorn, and candy buttons), and invite your friends or family to dress in vintage-inspired outfits. Add a bubblegum pink backdrop for photo ops and you’ve got yourself a full-on strawberry soda shop experience.
Lights, frosting, action.
Strawberry Soda Shop Sheet Cake
Ingredients
For the cake:
- 1 box white cake mix
- 3 large eggs
- 1/3 cup vegetable oil
- 1 cup strawberry soda (like Crush or Fanta)
- 1 (3 oz) box strawberry gelatin mix
For the frosting:
- 2 sticks salted butter, softened
- 1 (7 oz) jar marshmallow fluff
- 1½ cups powdered sugar
- 2–3 tbsp strawberry soda
- ½ tsp strawberry extract
- Pink and green food coloring (optional)
Toppings:
- Strawberry candies (I used sour Jolly Ranchers)
Tools
- Wilton 1M piping tip
- Piping bags
- Chefmaster gel colors in Rose Pink and Leaf Green
Instructions
- Preheat the oven to 350°F. Spray a 9×13-inch pan with baking spray.
- In a large bowl, mix together cake mix, eggs, oil, soda, and strawberry gelatin until smooth.
- Pour into the prepared pan and bake according to the box directions. Let cool completely.
- In a mixing bowl, beat the butter until smooth. Add marshmallow fluff and mix well.
- Add powdered sugar, strawberry soda, and extract. Beat until fluffy and smooth.
- Divide the frosting into three bowls. Leave one white, tint one pink, and one green. Spread the white frosting over the entire surface of the cooled cake. Fill a piping bag fitted with a Wilton 1M tip with green frosting and pipe a basic shell border around the edge. Using another piping bag with a 1M tip, pipe pink frosting in angled “V” shapes (like a braided or chevron pattern) just inside the green border, layering in a criss-cross motion along all four edges.
- Press strawberry candies gently into the pink piping to complete your soda shop look.
