Lemon Blueberry (box) cake

I made this for a little Mother's Day dinner with our friends. It turned out fantastic.

This box mix. It's my dirty little secret. This particular box mix I just followed the instructions on the back. It was super moist and light. I used that and added lemon zest to the mix, threw some blueberries in as well and called it a day. I know that you would probably prefer accurate measurements however I just threw things in all willy nilly like. So I apologize for that.  

The frosting..I would do cream cheese icing next time.. Just add some lemon juice (fresh) and zest. This was just milk/vanilla/powdered sugar/lemon juice/lemon zest. Mix it to the consistency of your choosing and pour it over that beautiful blueberry filled cake.
