I love to bake. It's cathartic for me.
Many times I've baked a cake from scratch - and made a huge mess in the process.
I'm learning though that doctoring a store bought cake mix is faster, easier, and often just as tasty.
A few things you can do to make a cake from a box taste more like a cake from scratch.
1 - add a small package of instant pudding in a flavor that compliments the cake mix
2 - add one cup sour cream
3 - use buttermilk or milk instead of water
Not only is the batter absolutely fluffy, rich, and quite heavenly, but it bakes up well, too (but it does take a bit longer than the instructions on the box tell you so watch carefully.).
My first attempt at a doctored mix turned out fabulous. I had a regular yellow cake mix, did all of the above and for my pudding added a white chocolate instant pudding. I never actually got to eat one of the finished products but the batter was enough to satisfy my sweet tooth for the day.
