I was given a complimentary copy of the Simple & Delicious cookbook to review, with no obligation. All opinions are my own. 

After my kids went back to school, I wanted to make a new treat for them when they came home “starving”. I was looking for really easy and also did not want to go to the store for any ingredients. I know, a tough bill to fill.

So, I took to my preview copy of the Simple & Delicious Cookbook. This recipe spoke to me…easy, cake mix, white chocolate chips, jimmies (or sprinkles). Lo and behold, I had all of the ingredients so I set off to make it.

When my kids arrived home from school, “starving”, they were pleasantly surprised with their festive treat. These cake mix bars are also perfect for a birthday or holiday. They are so festive with the addition of jimmies.

Mix up the jimmies (you may call them sprinkles), using red, green and white for Christmas or pastels for spring. I also think they would make a great base for an ice cream sundae.

Tips and Tricks to Making Easy Cake Mix Bars

  • Using a yellow cake mix makes this recipe more flavorful. You could choose to use a butter yellow cake mix but I don’t suggest a white cake mix. White cake mixes are softer when made. Yellow has more substance which you need with the addition of the white chocolate chips and jimmies, also known as sprinkles.
  • Make sure all ingredients are room temperature.
  • It’s OK to use whole or 2% milk. I have used both of these when I’ve made this recipe. I have not tried this recipe with non-dairy milk products.
  • You may also know these treats as funfetti cake bars due to the addition of the sprinkles. These cake bars travel well making them perfect for a potluck party.

What Are Sprinkles Made Of?

The simple answer is a number of things including sugar, corn syrup, cornstarch, wax and artificial flavors, though rainbow sprinkles really don’t have any flavor. Chocolate ones have the addition of cocoa and mildly taste like chocolate.
