How to Make It

Preheat
Preheat the oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.

In a large bowl, combine vegetable oil, butter, lemon zest, and sugar. Mix until smooth.
Add eggs
Add eggs one at a time, mixing well after each addition.
Stir in buttermilk
Stir in buttermilk, lemon extract, and vanilla extract until fully combined.
Combine dry ingredients
In another bowl, whisk together flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in blueberries
Fold in fresh blueberries gently to avoid breaking them.
Pour into pans
Divide the batter evenly between the prepared cake pans.
Bake
Bake in preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Cool cakes
Let cakes cool in the pans for 10 minutes, then turn out onto wire racks to cool completely.
Prepare icing
For the lemon icing, beat butter and cream cheese in a bowl until smooth. Gradually add powdered sugar and mix until creamy. Add enough milk to achieve desired consistency, then stir in vanilla extract, lemon zest, and a pinch of salt.
Assemble the cake
Once cakes are completely cool, spread the lemon icing between the layers and on top of the cake as desired.
