Instructions:
- Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
- Cream the 225g unsalted butter and 400g granulated sugar until pale and fluffy. Beat in the 4 eggs one at a time.
- Alternate adding the dry ingredients (cake flour, baking powder, salt) and the whole milk, stirring until the batter is smooth.
- Divide batter evenly between pans and bake for 30-35 minutes until a toothpick comes out clean.
- Cool cakes in the pan for 10 minutes, then transfer to a wire rack to cool completely.
- Use a serrated knife to slice off the domed tops of the cakes to create a level surface.
- Prepare buttercream by whipping 450g softened butter, 720g powdered sugar, heavy cream, vanilla extract, and salt.
- Apply a thin crumb coat of buttercream over the entire cake and chill in the refrigerator for 30 minutes.
- Apply the final thick layer of buttercream, smoothing the sides with an offset spatula.
- Mix blue frosting and pipe a curving stethoscope line around the side of the cake.
- Use white fondant to create a graduation cap and apply gold luster dust for detail.
- Pipe the graduate's name and 'RN' or 'BSN' using the remaining buttercream.
