Instructions

Blueberry Banana Cake:

  • Preheat oven to 350F. Grease and flour three 6" cake rounds, line with parchment.

  • In a medium bowl, whisk cake flour, baking powder, and salt. Set aside
.
  • Beat butter until smooth. Add sugar and beat on med-high until pale and fluffy (2-3mins).

  • Reduce speed and add eggs one at a time, fully incorporating after each addition. Add vanilla and mashed bananas and mix until well combined.

  • Alternate adding flour mixture and buttermilk, beginning and ending with flour (3 additions of flour and 2 of milk). Fully incorporating after each addition. Do not overmix.
  • Gently fold in blueberries, being careful not to break them.

  • Spread batter evenly into prepared pans and bake for 30mins or until a toothpick inserted into the center comes out mostly clean.

  • Place cakes on wire rack to cool for 10mins then turn out onto wire rack to cool completely.


Cream Cheese Frosting:

  • Using a stand mixer or hand mixer beat butter until pale and creamy.
  • Reduce speed to low. Add powdered sugar 1 cup at a time and mix on low until well blended. Increase speed to medium and beat for 3 minutes. Add vanilla and continue to beat on medium for 1 minute.
  • Slowly add chilled cream cheese one cube at a time (about 1 tablespoon at a time). Beat well until blended and ensure no lumps of cream cheese remain.
  • If needed, add cornstarch or meringue powder 1 tablespoon at a time to stiffen the frosting (I didn't but this is an option).
  • Run mixer on low for a couple of minutes to remove any air bubbles.

Assembly:

  • Place one layer of cake on a cake stand or serving plate. Top with 2/3 cup of frosting. Repeat with remaining layers and apply a thin coat of frosting all over the cake. Chill for 20mins. 
  • Use the remaining frosting to frost the cake, and do a rustic swirl on the sides and top with an offset spatula if desired.
  • Top with fresh blueberries and thyme sprigs if desired.
