# Directions:

02 - Whisk together flour, baking powder, and salt in a medium bowl until well combined.
03 - Beat butter and sugar in a large bowl until light and fluffy, approximately 3-4 minutes.
04 - Add eggs one at a time, beating thoroughly after each addition. Mix in vanilla bean paste until 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 using an offset spatula.
07 - Bake for 30-35 minutes until a toothpick inserted into the center emerges clean.
08 - Let cakes rest in pans for 10 minutes, then invert onto wire racks to cool completely before frosting.
09 - Beat butter on medium speed until creamy, about 2 minutes. Gradually incorporate powdered sugar on low speed. Add milk, vanilla, and salt. Beat on high speed for 3 minutes until light and fluffy.
10 - Place first cake layer on serving plate. Spread generous layer of buttercream over top. Position second layer. Frost top and sides of cake completely.
11 - Apply sprinkles or arrange edible flowers on top of frosted cake as desired.
