Equipment

  • 1 9x9 inch square baking pan greased and floured
  • 1 electric mixer
  • 1 Mixing Bowl large
  • 1 Wire Rack
  • 1 Spatula

Ingredients
  

Dry Ingredients

  • 2 1/2 cups all-purpose flour
  • 2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt

Wet Ingredients

  • 1 cup unsalted butter softened
  • 2 cups granulated sugar
  • 4 large eggs room temperature
  • 1 tsp vanilla extract
  • 1 cup buttermilk

Frosting

  • 1 cup unsalted butter softened
  • 4 cups confectioners' sugar
  • 2 tsp vanilla extract
  • 2-4 tbsp heavy cream

Instructions
 

Preparation

  • Preheat your oven to 350°F and grease a 9x9 inch square baking pan. Line the bottom with parchment paper for easy removal.
  • In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
  • In another bowl, use an electric mixer to cream the butter and sugar until light and fluffy. This should take about 3-5 minutes.
  • Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
  • Alternately add the dry ingredients and buttermilk to the creamed mixture, starting and ending with the dry ingredients. Mix until just combined.
  • Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 35-40 minutes or until a toothpick inserted into the center comes out clean.
  • Remove the cake from the oven and let it cool in the pan for 10 minutes. Then, turn it out onto a wire rack to cool completely.

Frosting

  • In a large bowl, beat the butter until creamy. Gradually add confectioners' sugar, beating until smooth. Add vanilla and enough heavy cream to achieve desired consistency.
  • Once the cake is completely cool, apply a crumb coat and refrigerate for 20 minutes. Then, apply the final layer of frosting, smoothing it with a spatula.
  • Decorate with minimalist elements such as edible pearls or a small fondant graduation cap. Keep the design simple to maintain the minimalist theme.

Serving

  • Use a sharp knife to cut the cake into slices. Serve at room temperature for the best flavor and texture.

Storage

  • Store any leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, freeze individual slices and thaw before serving.

Notes

Pro Tips: Ensure even baking by rotating the cake halfway through. Use a bench scraper to smooth the frosting. Experiment with different minimalist designs for a unique look.
Ingredient Substitutions: Substitute buttermilk with a mixture of milk and vinegar. Use almond extract for a different flavor profile.
How to Serve: Best served at room temperature. Complement with a scoop of vanilla ice cream for added indulgence.
Storage & Freshness: Store in an airtight container to maintain freshness. Freeze for up to 3 months for make-ahead convenience.
Make-Ahead Tips: Bake the cake a day in advance and frost it on the day of the event for best results.
