# Directions:

01 - Preheat oven to 350°F. Grease and line two 9-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt until evenly distributed.
03 - In a large bowl, beat butter and sugar together on medium-high speed until light and fluffy, approximately 3-4 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla bean paste until fully incorporated.
05 - Add flour mixture in three parts, alternating with milk, beginning and ending with flour. Mix until just combined; avoid overmixing to prevent tough texture.
06 - Divide batter evenly between prepared pans. Smooth tops with a spatula. Bake for 30-35 minutes until a toothpick inserted into the center comes out clean.
07 - Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely before frosting.
08 - Beat butter on medium speed until creamy, about 2 minutes. Gradually add powdered sugar on low speed. Add milk, vanilla, and salt; beat on high speed for 3 minutes until fluffy and smooth.
09 - Place one cake layer on a serving plate. Spread a generous layer of buttercream on top. Position second layer over first, then frost the top and sides evenly.
10 - Finish with sprinkles or edible flowers if desired.

# Expert Advice:

01 -
  • The buttercream is so pillowy you might find yourself eating it straight from the bowl when no ones watching
  • This cake manages to feel fancy enough for a wedding but humble enough for a Tuesday night birthday
02 -
  • Room temperature ingredients are the difference between a tender crumb and a dense disappointment so plan ahead
  • Overmixing once the flour is added develops gluten and makes the cake tough so stop as soon as you no longer see dry streaks
03 -
  • Rotate your cake pans halfway through baking for even layers since most ovens have hot spots
  • Tap the filled pans gently on the counter before baking to release any trapped air bubbles
