First of all...
Happy Birthday, Ana!
Sorry there aren't any balloons or buns, but I do have a good birthday recipe to share. I tried it out after having a piece of this cake at a restaurant, but I've only made it once and didn't take a picture. Basically, you substitute the water and oil the cake mix calls for with a can of cherry pie filling. It's incredibly good and moist!
Chocolate Cherry Cake
1 box chocolate cake mix
1 can cherry pie filling
I noticed some other versions calling for a tsp of either vanilla extract or almond extract. You can add it if you like, but I'm not sure it needs it.
Mix by hand and pour into a greased and floured 9 X 13 pan. Bake at 350 for 30-35 min or until a toothpick inserted in the center comes out clean. Frost when cooled. I used chocolate icing, but I'm thinking cream cheese would be incredibly good on this.
