Orange Supreme Cake with Homemade Buttercream Frosting

Last night Mel, Kendra, and I were all hungry, so we decided to make a cake. We used an orange supreme cake mix, and then made homemade buttercream frosting. This is the recipe we used for the frosting (thanks to http://whisk-kid.blogspot.com):

5 egg whites

1 c sugar

2 sticks butter, room temp

1 tsp lemon extract (we used vanilla extract)

Cook the egg whites and sugar in a small saucepan over medium heat, whisking constantly, until the sugar is completely dissolved (test by rubbing some between your fingers. If it's completely smooth, it's done). Pour into another bowl (a stand mixer is preferable) and whip on high speed until room temp. Then, on a medium-slow speed, add the butter, waiting until each piece is completely incorporated before adding the next. After all the butter has been added, turn the mixer back to high speed and whip until it has come together, about five minutes. Add the extract, beat briefly and then use.

It was really good, though next time I would wait until the cake had completely cooled before putting the frosting on (we were just hungry and impatient).
