Ingredients
2 ½ cups All-purpose flour
1 ¾ cups Granulated sugar
1 tablespoon Baking powder
½ teaspoon Salt
1 cup Unsalted butter
4 Large eggs
1 cup Whole milk
2 teaspoons Vanilla extract
Gel variety Blue food coloring
6–8 cups Powdered sugar
1 ½ cups Unsalted butter
4–6 tablespoons Heavy cream or milk
1 teaspoon Vanilla extract
Optional Edible pearls
Optional Crushed graham crackers
Optional Candy fish/seashells
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line them with parchment paper circles. This prevents sticking and ensures easy removal of your lovely cake layers
- In a large bowl, whisk together the sifted all-purpose flour, granulated sugar, baking powder, and salt. Make sure these ingredients are thoroughly combined to ensure an even rise and flavor distribution throughout your Water Themed Cake
- In a separate, larger bowl, or the bowl of a stand mixer, cream the softened unsalted butter until it becomes light and fluffy, about 2-3 minutes. Gradually add the room temperature eggs, one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. This step incorporates air, making your cake tender
- Add about one-third of the dry ingredients to the butter mixture, mixing on low speed until just combined. Next, pour in half of the room temperature whole milk and vanilla extract, mixing until smooth. Repeat with another third of the dry ingredients, then the remaining milk, and finally the last of the dry ingredients. Mix until *just* combined; overmixing develops gluten and can lead to a tough cake
- Divide the cake batter evenly between your two prepared cake pans. Smooth the tops with a spatula. Bake for 30-35 minutes, or until a wooden skewer inserted into the center of the cakes comes out clean. Baking times can vary, so keep an eye on your Water Themed Cake layers
- Remove the cakes from the oven and let them cool in their pans on a wire rack for about 10-15 minutes. Then, invert them onto the wire rack to cool completely. Cooling thoroughly prevents the frosting from melting
- While the cakes cool, prepare your buttercream. In a large bowl, beat the softened unsalted butter until creamy. Gradually add the powdered sugar, one cup at a time, mixing well after each addition. Once all the sugar is incorporated, add the vanilla extract and 4 tablespoons of heavy cream or milk. Beat on medium-high speed for 3-5 minutes until the frosting is light, fluffy, and smooth. Add more cream or milk, one tablespoon at a time, if you need a thinner consistency
- Divide the buttercream into 2-3 bowls. Leave one bowl white or a very light blue. In the other bowls, add varying amounts of blue gel food coloring to create different shades of blue (light blue, medium blue, dark blue). Mix each bowl well. These shades will create the beautiful ombré effect for your Water Themed Cake
- Once the cakes are completely cool, level them if necessary using a serrated knife. Place one cake layer on your serving platter or cake stand. Spread a generous layer of your darkest blue frosting on top. Place the second cake layer on top. Apply a thin "crumb coat" of the medium blue frosting all over the top and sides of the cake. This traps any loose crumbs. Chill the cake in the refrigerator for 15-20 minutes
- Apply the remaining frosting in your desired ombré pattern, or use different shades to pipe waves. Start with the darkest blue at the bottom, moving to lighter shades towards the top. Smooth with an offset spatula or bench scraper. Finally, decorate with edible pearls for bubbles, crushed graham crackers for sand, or candy fish to bring your Water Themed Cake to life
- Chill your decorated Water Themed Cake for at least 30 minutes before slicing and serving. This helps the frosting set and makes for cleaner cuts
Notes
Always use room temperature ingredients for your cake batter to ensure proper emulsification and a tender, even crumb.
Avoid overmixing the batter once flour is added to prevent a tough, chewy cake.
Sift powdered sugar for the buttercream to prevent lumps and achieve a smooth, silky frosting.
Use gel food coloring for vibrant hues without watering down the frosting; start with a tiny amount.
For the ombré effect, apply frosting in bands and smooth with a bench scraper or offset spatula.
Allow cake layers to cool completely on a wire rack before frosting to prevent melting.
Store frosted cake in an airtight carrier at room temperature for up to 2 days, or refrigerated for up to 5 days, covered tightly. Before serving a refrigerated cake, let it sit at room temperature for 30 minutes to an hour to soften the buttercream.
