Ingredients
For this cake I rely on a handful of pantry staples that work together to create a moist crumb and a striking color. The cake batter uses cake flour, sugar, butter, and buttermilk for tenderness, while cocoa powder and blue spirulina provide depth and hue. The frosting is a classic cream cheese blend brightened with lemon zest, giving the dessert a fresh finish that cuts through the richness.
Cake Batter
- 2 ½ cups cake flour
- 1 ½ cups granulated sugar
- ¼ cup unsweetened cocoa powder
- 1 tsp baking soda
- ½ tsp fine sea salt
- ½ cup unsalted butter, softened
- 2 large eggs, room temperature
- 1 cup buttermilk, chilled
- 2 tbsp natural blue spirulina powder
- 1 tsp vanilla extract
- 1 tbsp white vinegar
Cream Cheese Frosting
- 8 oz cream cheese, softened
- ¼ cup unsalted butter, softened
- 3 cups powdered sugar, sifted
- 1 tsp vanilla extract
- ½ tsp lemon zest
Garnish (Optional)
- Edible silver pearls
- Fresh berries for contrast
These ingredients work in harmony to give the cake its signature texture and color. The combination of buttermilk and vinegar creates a tender crumb while reacting with the baking soda for a gentle rise. Blue spirulina adds a natural, vivid hue without the artificial aftertaste of food coloring. The cream cheese frosting, enriched with lemon zest, adds a bright tang that cuts through the chocolate‑blue base, making each bite feel balanced and luxurious.
Step-by-Step Instructions
Preparing the Batter
Start by preheating the oven to 350°F (175°C) and greasing two 9‑inch round cake pans. In a large bowl whisk together cake flour, cocoa powder, baking soda, and salt. In a separate bowl, cream butter and sugar until light and fluffy, about 3‑4 minutes. Add the eggs one at a time, beating well after each addition, then stir in vanilla and vinegar. Finally, blend the dry ingredients with the wet, alternating with the chilled buttermilk, and fold in the blue spirulina until the batter is a uniform sapphire shade.
Baking the Cake
- Divide the batter. Evenly spoon the batter into the prepared pans, smoothing the tops with a spatula. This ensures both layers bake at the same rate and achieve an even crumb.
- Bake. Place the pans on the middle rack and bake for 22‑25 minutes, or until a toothpick inserted into the center comes out clean. The edges should be set while the center remains slightly springy.
- Cool. Allow the cakes to cool in the pans for 10 minutes, then invert onto a wire rack to cool completely. Cooling fully prevents the frosting from melting when spread.
Frosting & Assembly
- Make the frosting. Beat cream cheese and butter together until smooth. Gradually add the powdered sugar, mixing on low speed to avoid a sugar cloud. Once incorporated, blend in vanilla and lemon zest for a fresh zing.
- Level the layers. Using a serrated knife, trim the tops of each cake layer so they are flat. This creates a stable base for stacking.
- Assemble. Place the first layer on a serving plate, spread a generous dollop of frosting, then top with the second layer. Apply a thin “crumb coat” over the entire cake, chill for 15 minutes, and finish with a smooth final coat of frosting.
- Garnish. Sprinkle edible silver pearls around the edge or scatter fresh berries for a pop of color. Refrigerate the finished cake for at least 30 minutes before slicing to set the frosting.
Tips & Tricks
Perfecting the Recipe
Room‑temperature ingredients. Keep butter, eggs, and buttermilk at room temperature to ensure a smooth batter and even rise.
Do not over‑mix. Once the dry ingredients are added, stir just until combined; over‑mixing creates a dense crumb.
Use a light hand with spirulina. Too much can turn the cake gray; start with 2 tbsp and adjust for desired intensity.
Chill the crumb coat. A short chill solidifies the first frosting layer, preventing cracks when you apply the final coat.
Flavor Enhancements
Add a tablespoon of almond extract to the batter for a subtle nutty note, or fold in finely chopped white chocolate chips for extra texture. A drizzle of raspberry coulis on the plate adds a tart contrast that brightens the blue hue.
Common Mistakes to Avoid
Skipping the cooling step before frosting can cause the butter in the frosting to melt, resulting in a runny finish. Also, avoid opening the oven door during the first 15 minutes of baking; temperature fluctuations can cause the cake to sink.
Pro Tips
Use parchment paper. Lining the pans ensures a clean release and protects the delicate edges.
Invest in an offset spatula. It makes spreading frosting evenly and creating smooth swirls effortless.
Measure flour correctly. Spoon the flour into the measuring cup and level it; packing flour leads to a dry cake.
Finish with a chill. A final 30‑minute chill before slicing locks in moisture and gives a clean cut.
Variations
Ingredient Swaps
Replace the spirulina with natural blueberry puree for a slightly sweeter hue, or use matcha powder for a green velvet twist. For a dairy‑free version, substitute butter with coconut oil and cream cheese with a vegan cream cheese alternative.
Dietary Adjustments
Swap all‑purpose flour for a gluten‑free blend that includes rice flour and tapioca starch. Use a sugar substitute like erythritol in the frosting for a low‑sugar option, and add a splash of almond milk if you need a dairy‑free liquid.
Serving Suggestions
Serve the cake with a dollop of lightly sweetened whipped coconut cream for extra fluffiness, or accompany it with a scoop of vanilla bean ice cream. Pairing with a glass of chilled rosé or a citrusy mocktail highlights the cake’s bright flavors.
Storage Info
Leftover Storage
Allow any leftover cake to cool completely, then wrap each slice tightly in plastic wrap and place them in an airtight container. Store in the refrigerator for up to four days. For longer keeping, freeze the wrapped slices in a freezer‑safe bag for up to three months; thaw in the fridge overnight before serving.
Reheating Instructions
Reheat individual slices in a preheated 300°F (150°C) oven for 10‑12 minutes, covering loosely with foil to prevent the frosting from drying. Alternatively, microwave a slice on medium power for 20‑30 seconds, adding a splash of milk if the cake feels dry. Serve immediately for the best texture.
