Equipment

  • Hand Mixer or Stand Mixer
  • 8x8 Baking Pan

Ingredients

  • 15.25 ounces chocolate cake mix 1 box dry mix*
  • ½ cup unsalted butter melted & slightly cooled
  • 1 large egg room temperature
  • 1 teaspoon pure vanilla extract
  • ⅓ cup white chocolate chips **
  • ⅓ cup milk chocolate chips **
  • ⅓ cup semi sweet chocolate chips **
  • ½ cup sweetened condensed milk ***

Instructions

  • Preheat oven to 350℉.
  • Line an 8”x8” baking pan with parchment paper. Leave the sides a little higher than the pan so the bars can be lifted out easily after they’ve cooled. Spray the parchment paper lined pan with non-stick cooking spray and set aside.
  • In a large bowl, beat together dry cake mix, butter, egg, and vanilla extract until fully combined (about 30 seconds).

  • Stir in all chocolate chips.

    White, milk, and semi-sweet chocolate chips added to chocolate cake bar batter.
  • Press about ⅔ of the dough mixture into the bottom of the prepared pan. This dough will be a thick, cookie dough consistency.

  • If spreading the dough gets tough, lightly spray a spatula with non-stick cooking spray to help spread out the bottom layer.
  • Spread the sweetened condensed milk evenly over the first dough layer.

  • Press the remaining ⅓ of dough into super flat pieces and cover as much of the sweetened condensed milk layer with the dough as possible.

  • Place baking tray in oven and bake for 29 to 31 minutes. The middle will look set and edges will be slightly browned.

  • Be careful not to over-bake or these bars will lose the ooey gooey texture.
  • Let brownies cool in the pan for at least 60 minutes before removing from pan and slicing into 16 squares. For clean edged squares, wipe the knife with a damp cloth in between cutting each row.

Notes

*You can use any brand or type of chocolate cake mix you prefer. Double check the box and make sure it contains 15.25 ounces. Add the dry mix only -- you do not need additional ingredients listed on the box.
**You can use all one type of chocolate chip, or any combination you prefer. Butterscotch or peanut butter chips could be used as well.
***This ingredient is key for an ooey gooey texture. Without it, these bars will be more cake-like.
Becky's Top Tips:
  • Prepping the pan with parchment and non-stick spray really makes it easy to get these brownie bars out of the pan later.
  • This recipe is quick to mix with an electric mixer, but you can mix by hand using a little elbow grease.
  • Mix just until the batter is well-combined. Too much mixing and the dough may bake up a little tough or dry.
  • The longer these bake, the more they will lose the gooey texture. So check for doneness a little early. If a toothpick inserted in the center comes out with wet batter instead of crumbs, it needs to keep baking.
Storage: Store cake mix bars in an airtight container at room temperature for up to 3 days, or in the fridge for up to 1 week.
