Ingredients
Scale
- 1 box white cake mix (15.25 oz)
- 1 cup water
- 1/2 cup vegetable oil
- 3 large eggs
- 1/4 cup rainbow sprinkles (optional)
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- 1 tablespoon vanilla extract
- 1–2 tablespoons milk or heavy cream
- Optional Toppings: Extra rainbow sprinkles, Mini candies or cookies, Colorful whipped cream
Instructions
- Preheat your oven to 350°F (175°C). In a large bowl, combine the white cake mix, water, vegetable oil, and eggs. Beat the mixture on medium speed for about 2 minutes until the batter is smooth and well combined. If you’re using rainbow sprinkles for a fun confetti look, gently fold them in at the end.
- Pour the batter into a greased 9×13-inch baking pan and spread evenly. Bake for 25–30 minutes or until a toothpick inserted in the center comes out clean. Once baked, allow the cake to cool completely on a wire rack.
- In a clean bowl, beat the softened butter until smooth and creamy. Gradually add in the powdered sugar, one cup at a time, beating well after each addition. Mix in the vanilla extract and just enough milk or cream to reach your desired consistency. Beat for another 2–3 minutes until light and fluffy.
- Cut the cooled cake into small cubes or rounds using a cookie cutter that fits your jar. Begin layering the jars or cups: a layer of cake, followed by a swirl of frosting (use a piping bag for a clean look), and repeat until the jar is full. Finish with a decorative swirl of frosting on top and a generous sprinkle of colorful toppings.
- Place the dessert cups in the refrigerator for at least 30 minutes. This helps set the frosting and improves the overall texture.
Notes
- Always let the cake cool fully before assembling to prevent frosting from melting.
- Use a piping bag for cleaner, neater layers.
- Clear jars show off the layers beautifully.
- Store covered in the fridge up to 4 days.
- Variations: Try chocolate cake with mint frosting, red velvet with cream cheese, or lemon cake with blueberry filling.
