Preheat the oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing and lightly flouring them.

In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.

Add one egg at a time, mixing well after each addition. Stir in the vanilla extract and orange zest.

Gradually add the dry mixture to the wet ingredients, alternating with the milk. Be and end with the flour mixture. Then stir in the fresh orange juice until just combined.

Divide the batter evenly between the prepared pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Let them cool in the pans for about 10 minutes before transferring to wire racks to cool completely.

In a large bowl, beat the softened butter until creamy. Gradually mix in the powdered sugar, orange juice, and zest, and beat until the frosting is fluffy.

Once the cake layers are completely cool, frost the top of one layer, place the second layer on top, and frost the top and sides of the cake.

Slice the cake and serve chilled for the best flavor, and enjoy the memories it brings!
