06 - Divide batter evenly between prepared pans. Smooth tops with a spatula.
07 - Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

# Expert Tips:

01 -
  • The vanilla bean paste creates these gorgeous little flecks throughout every bite, like edible confetti
  • Buttercream this smooth spreads like a dream and tastes like something from a proper bakery case
  • The cake itself is tender enough to slice cleanly but sturdy enough to survive being stacked twice by accident ask me how I know
02 -
  • Room temperature ingredients are not optional suggestions they are the difference between bakery beautiful and homemade disappointment
  • Overmixing after adding flour activates gluten and turns tender cake into something resembling sad cornbread
  • Simple syrup brushed on cooled layers keeps this cake moist for days which matters more than you think until its day three and someone wants another slice
03 -
  • Vanilla bean paste costs more but those visible seeds make people think you spent hours on something that actually came together in an afternoon
  • If your oven runs hot rotate the pans halfway through baking so both layers rise evenly
