Ingredients:
- 2 ½ cups (310g) All-purpose flour
- 1 ½ cups (300g) Granulated sugar
- 1 tbsp (12g) Baking powder
- ½ tsp (3g) Salt
- ¾ cup (170g) Unsalted butter, softened
- 1 cup (240ml) Whole milk, room temperature
- 3 large eggs, room temperature
- 1 tbsp (15ml) Vanilla bean paste
- 2 cups (450g) Unsalted butter, softened
- 6 cups (720g) Powdered sugar, sifted
- 3 tbsp (45ml) Heavy cream
- 1 tsp (5ml) Vanilla extract
- 1 drop (1ml) Red food coloring
Instructions:
- Preheat the oven to 350°F (175°C). Grease a 9x13 inch baking pan and line it with parchment paper.
- In one large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt.
- Add softened butter, room-temperature milk, eggs, and vanilla bean paste to the dry ingredients. Beat on medium speed for 2 minutes until the batter is smooth.
- Pour the batter into the prepared pan, smoothing the top with a spatula, and bake for 30-35 minutes until the edges pull away from the pan and a toothpick inserted in the center comes out clean.
- Allow the cake to cool completely before frosting.
- Whip together the buttercream ingredients (butter, powdered sugar, heavy cream, and vanilla extract) until fluffy.
- Apply a thin crumb coat of buttercream to the cake and chill in the refrigerator for 30 minutes.
- Apply a final thick layer of white frosting, smoothing with an offset spatula. Use red-tinted frosting to pipe a heart or medical cross, and white frosting to pipe 'RN' or 'Congrats Grad!'.
