When I decided to bake the Pisces Cake, I wanted it to reflect both the characteristics of the zodiac sign and the vastness of the universe. Using a swirling technique allowed me to blend shades of blue, purple, and black, mimicking the beautiful cosmos. I experimented with adding a hint of lavender to the frosting, which paired surprisingly well with the chocolate cake underneath.

One unique tip I learned was to use edible glitter to give the cake a galaxy-like shimmer. This simple addition transformed a regular dessert into something truly magical. Watching the cake come together was such a rewarding experience, and I can't wait to share this creation with others!

Understanding the Ingredients

The choice of cocoa powder in this Pisces Cake is essential for achieving a rich chocolate flavor and a deep, dark color. Unsweetened cocoa provides the necessary balance to the sweetness from other ingredients, ensuring the cake doesn’t become overwhelmingly sweet. If you prefer a different chocolate flavor, consider using Dutch-processed cocoa for a smoother, milder taste.

Lavender extract adds a floral note that beautifully complements the chocolate in the frosting. Be cautious with the amount; start small and taste as you go. If fresh lavender is accessible, a few sprigs can be infused in the heavy cream for a natural flavor boost. Just strain it out before mixing to avoid any texture issues.

Tips for Perfecting Your Technique

When mixing the cake batter, it’s important to follow the order of ingredients for the best results. Mixing in the dry ingredients first helps evenly distribute the leaveners, while adding boiling water at the end ensures all ingredients are combined smoothly, resulting in a moist cake. Use a rubber spatula to gently fold in any remaining streaks of flour, avoiding overmixing which can lead to a tough texture.

Creating the galaxy swirls is a fun technique that allows for artistic expression. After crumb coating, use a clean spatula to dip into each color of frosting and apply them on the cake simultaneously. By rotating the spatula in swirling motions, you can achieve a beautiful marbling effect. Don’t worry if it doesn’t look perfect right away—practice makes progress!

Ingredients

Gather these high-quality ingredients before you start baking for the best results.

For the Cake

2 cups all-purpose flour
1 ½ cups granulated sugar
¾ cup unsweetened cocoa powder
1 ½ teaspoons baking powder
1 ½ teaspoons baking soda
1 teaspoon salt
2 large eggs
1 cup whole milk
½ cup vegetable oil
2 teaspoons vanilla extract
1 cup boiling water

For the Frosting

1 cup unsalted butter, softened
4 cups powdered sugar
¼ cup heavy cream
2 teaspoons lavender extract
Food coloring (purple, blue, black)
Edible glitter for decoration

Ensure all ingredients are at room temperature for a smooth batter and frosting.

Instructions

Before starting, make sure your workspace is clean and organized. Preheat your oven to 350°F (175°C).

Prepare the Cake Batter

In a large bowl, mix together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Add the eggs, milk, oil, and vanilla extract, and mix until well combined. Carefully stir in the boiling water until the batter is smooth.

Bake the Cakes

Pour the cake batter evenly into two greased 9-inch round cake pans. Bake in the preheated oven for 30–35 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool completely.

Make the Frosting

In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar, alternating with the heavy cream, beating until smooth. Add lavender extract and beat until well combined.

Divide frosting into three bowls for coloring.

Color the Frosting

Color one bowl of frosting blue, another purple, and leave the third bowl black. Use food coloring to achieve the desired shades.

Assemble the Cake

Level the cooled cakes and place one layer on a serving plate. Spread a layer of frosting on top and place the second cake layer over it. Crumb coat the cake with a thin layer of frosting and refrigerate for 30 minutes.

Create Galaxy Swirls

After chilling, use a spatula to apply blue, purple, and black frosting, swirling them together to create a galaxy look. Add edible glitter for a shimmering effect.

Once completed, let the cake set for a bit before slicing to ensure it holds its shape.

Pro Tips

For added texture, consider adding crushed graham crackers or chocolate wafers to the frosting between the layers. Don’t forget to give the frosting a quick whip before applying for that airy texture.

Storage and Make-Ahead Tips

This cake can be made a day in advance, which can enhance its flavor as the ingredients settle together. Store the un-frosted cake layers wrapped in plastic wrap at room temperature. Once frosted, refrigerate the cake to keep it fresh, as the frosting can soften if left out too long. Before serving, allow the cake to sit at room temperature for about 30 minutes to make slicing easier.

If you have leftover cake, it freezes well for up to three months. Wrap individual slices tightly in plastic wrap and place them in an airtight container. You can thaw them at room temperature or heat them in the microwave for a few seconds for a freshly-baked taste, perfect for a midweek treat.

Serving Suggestions

For an extra touch, pair your Pisces Cake with a scoop of vanilla ice cream or a dollop of whipped cream to contrast the rich chocolate flavor. The cold creaminess of ice cream can add another dimension to the overall experience, making it feel more indulgent.

To enhance the galaxy theme when serving, consider decorating the dessert table with starry motifs or using galaxy-themed plates. Not only will this elevate your presentation, but it creates an immersive experience for guests, making every bite more memorable.
