Neptune's Culinary Wonders: An Intergalactic Gastronomy Guide

Ingredients

2 cups of all-purpose flour
1 teaspoon of baking powder
1/2 teaspoon of baking soda
1/2 teaspoon of salt
1 cup of unsalted butter, softened
1 and 1/2 cups of granulated sugar
2 large eggs
2 teaspoons of pure vanilla extract
1 cup of buttermilk
Blue and green food coloring
For the icing:
1 cup of unsalted butter, softened
4 cups of powdered sugar
2 teaspoons of pure vanilla extract
3-4 tablespoons of milk
Blue and green food coloring

Steps and instructions

Preheat your oven to 350°F (175°C). Grease and flour your baking pans.
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
In a large bowl, cream the butter and sugar together until light and fluffy.
Beat in the eggs, one at a time, mixing well after each. Then stir in the vanilla.
Gradually beat in the flour mixture alternately with the buttermilk.
Divide the batter into two. In one part, add blue food coloring and in the other part, add green food coloring. Mix each until the color is evenly distributed.
Drop spoonfuls of the blue and green batter alternately into the prepared baking pans and then swirl together with a knife to create a marbled effect.
Bake for 20-25 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
Allow the cakes to cool in their pans over a wire rack for at least 10 minutes. Then remove the cakes from the pans and let them cool completely on the wire rack.
While the cakes are cooling, you can make the icing. In a large bowl, cream together the butter, powdered sugar, and vanilla. Beat in the milk, one tablespoon at a time, until the icing reaches the desired consistency. Divide the icing into two. In one part, add blue food coloring and in the other part, add green food coloring. Mix each until the color is evenly distributed.
Once the cakes have cooled, spread the icing between the layers, on the top, and around the sides of the cake. Alternate the colors to create a marbled effect with the icing as well.
Chill the cake in the fridge for at least 1 hour before serving.

Common questions

Can I use salted butter instead of unsalted? Yes, you can use salted butter, but it's best to reduce the added salt in the recipe to balance the saltiness.

How can I create a stronger marbled effect in the cake? You can create a stronger marbled effect by using a knife or skewer to swirl the blue and green batters more vigorously before baking.
How should I store the cake? Store the cake in an airtight container in the refrigerator. It can be stored for up to 3-4 days.
Can I freeze the cake? Yes, you can freeze the cake. Wrap it tightly in plastic wrap and place it in a freezer-safe container. It can be frozen for up to 2-3 months. Thaw it in the refrigerator before serving.

Origin stories

While the Neptune cake doesn't hail from a specific region, its name and visual appeal certainly do take inspiration from the planet Neptune, the eighth and farthest-known Solar planet from the Sun. What's unique about Neptune, the planet, is its striking blue color caused by methane in its atmosphere. This captivating cosmic hue has been the muse for many art forms, including this delightful cake recipe. Just like the mesmerizing swirls of teal and deep blue on the planet's surface, this cake features a blue and green marbled effect, both in the cake itself and the icing, making it a visually stunning dessert to behold, much like gazing upon Neptune in the night sky.
