Instructions
 

Make Cake Batter

  • I preheat the oven to 350°F (175°C), grease and line three 8-inch pans, and mix 2 ⅔ cups flour, 2 cups sugar, 1 tsp baking powder, ½ tsp baking soda, and 1 tsp salt in a mixer for these Key Lime Cake. I add ½ cup butter gradually, then ¼ cup oil and 1 tbsp lime zest. I whisk 1 ½ tbsp lime juice, 1 ½ cups milk, 2 eggs, and 1 tsp vanilla, then combine with dry mix until smooth.

Bake Cakes

  • I divide batter (~460g per pan) and bake for 26–28 minutes until a toothpick is clean for these zesty baked cakes.

Make Lime Curd

  • I whisk 2 egg yolks, ⅓ cup lime juice, 2 tbsp sugar, and ¼ tsp salt in a saucepan, add 2 tbsp butter, and cook until thickened, then strain and cool for these tangy lime treats.

Prepare Frosting

  • I beat ¾ cup butter and 6 oz cream cheese, add 4–5 cups powdered sugar, and mix in cooled curd for this simple recipe.

Assemble Cake

  • I level cakes, spread frosting and curd between layers, frost the outside, and decorate with ¼ cup graham crumbs for these citrusy dessert cakes.

Chill and Serve

  • I chill the cake for 30 minutes before slicing for these zesty baked cakes.
