  • Cake turntable (optional) optional
  • Piping bags and tips
  • Serrated knife or cake leveler

Ingredients
  

For the Cake Batter

  • 315 g all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 230 g unsalted butter softened
  • 400 g granulated sugar
  • 4 large eggs at room temperature
  • 1 tbsp pure vanilla extract
  • 240 ml whole milk at room temperature
  • Pink or blue gel food coloring for the reveal

For the Buttercream Frosting

  • 345 g unsalted butter softened
  • 750 g powdered sugar sifted
  • 45–60 ml heavy cream
  • 1 tbsp pure vanilla extract
  • A pinch of salt
  • Additional gel food coloring optional, for exterior design

For the Surprise Filling (optional)

  • 200 g colored sprinkles or candies in pink or blue

Instructions
 

Step 1: Prepare the Cake Batter

  • Preheat your oven to 350°F (175°C). Grease and line the cake pans with parchment paper.
  • In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
  • In a large bowl, beat the butter and sugar together on medium speed until fluffy, about 2–3 minutes. Add the eggs one at a time, then mix in the vanilla extract.
  • Gradually add the dry ingredients to the wet mixture, alternating with milk. Begin and end with the dry ingredients.

Step 2: Add the Surprise Color

  • Divide the batter into two bowls. Add pink or blue gel food coloring to one portion for the gender reveal layer. Mix until the color is uniform.
  • Pour the batter into the prepared pans (one plain and one colored) and smooth the tops with a spatula.

Step 3: Bake the Cakes

  • Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the cakes cool in the pans for 10 minutes, then transfer them to a cooling rack to cool completely.

Step 4: Prepare the Frosting

  • Beat the butter on high speed until creamy, about 2 minutes. Add the powdered sugar gradually, followed by the vanilla extract, heavy cream, and a pinch of salt. Beat until the frosting is smooth and spreadable.

Step 5: Assemble the Cake

  • Level the cakes with a serrated knife if needed. Place the plain cake layer on the bottom. If using a surprise filling, cut a small circle in the center of the colored layer, fill the cavity with sprinkles or candies, and cover it with the cut-out piece.
  • Stack the colored cake layer on top, ensuring the filling is sealed.

Step 6: Decorate

  • Use a crumb coat (thin frosting layer) to cover the cake and chill for 20 minutes. Apply a thicker frosting layer, smoothing it with an offset spatula. Add decorations such as piped designs or edible glitter as desired.
