Step 1

Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line three 6-inch round cake pans with baking or parchment paper.

Step 2

In a large mixing bowl, add flour, sugar, baking powder and salt. Whisk briefly. Add butter and beat with an electric mixer on low speed, until butter is broken into small pea-sized pieces and completely covered in flour.

Step 3

Next, add eggs, one at a time, while continuing to mix on low speed. Then, pour in milk and vanilla. Start to beat on low speed and then turn up to medium speed. Finally, add Greek yogurt. Mixture should be creamy and smooth.

Step 4

Divide cake batter between prepared pans. Bake for approximately 25-30 minutes or until a skewer inserted in the middle comes out clean. Carefully transfer cakes to a wire rack to cool completely.

Step 5

To make the frosting, add butter to a large mixing bowl. Beat with an electric mixer for 2 minutes or until smooth and creamy. Add vanilla.

Step 6

Add 2 cups of sugar, along with 2 tablespoons of milk, and continue to beat. Add remaining 2 cups of sugar and beat briefly until smooth. If the frosting is too thick, add an extra tablespoon of milk.

Step 7

Spread frosting on one cake layer, add the cake layer on top. Repeat. Then cover top and sides with frosting.
