Orange Cake with Orange Buttercream Frosting!

This is a cake I made for my boss' birthday tomorrow. He turns 65! It's an orange flavored white cake with marmalade filling and orange buttercream frosting, decorated with orange gummies. It's 100% homemade (except the gummies, of course). Here's the recipe:

Orange Cake

2 cups white sugar
1 cup butter
4 eggs
3 teaspoons orange extract
1 1/2 tablespoons orange zest
1/4 cup freshly squeezed orange juice
3 cups all-purpose flour
4 teaspoons baking powder
3/4 cup milk

Grease and flour two 9" cake pans and preheat the oven to 350 degrees.

Cream the sugar and butter and then add the eggs one at a time and beat till smooth. Stir in the orange extract and the orange zest. Add the orange juice and stir. Mix the flour and baking powder in a separate small bowl and then add to the batter. Add the milk, beat till smooth and then place in the two prepared pans. Bake at 350 for 30 minutes or until it tests done. Turn out onto wire racks after they cool for a few minutes and allow to cool thoroughly.

I filled my cake with marmalade (prepared) between the two layers. I then frosted the whole thing with buttercream frosting. I didn't measure anything so I can't exactly say how much sugar or milk I used in my buttercream, but I softened two sticks of butter and then added confectioner's sugar to make a stiff dough. I then drizzled in milk, maybe about 2 tablespoons' worth, mixed, and then added more sugar until it became the right consistency. I colored mine soft orange and then frosted the cake. I put orange gummies on, then piped leaves and writing onto the cake. Hope it tastes good!
