I am a bit of a gooey bar aficionado – you can see that I have a ton of gooey bar recipes. These are so good and full of chocolate!

This bar cookie recipe is easy because it starts with a cake mix. I make yellow cake mix cookie bars, but you could also use a white cake mix or any flavor you want. I just love cake mix cookie bar recipes because they’re easy, and you only need a handful of ingredients.

I like Betty Crocker cake mix cookie bars and have made all kinds of versions like chocolate cake mixbrowniesred velvet, and lemon cake mix. But you can use any cake mix brand that you like.

If you’ve never made gooey bars, the secret ingredient is sweetened condensed milk. It’s a type of canned milk where 60% of the water has been removed, and sugar is added. It’s cooked to a thick and gooey state before being canned. There is no substitution – the only way to make ooey gooey cake is with condensed milk!

When you combine the milk and chocolate chips, you get the best cookie bars made with cake mix. No one will ever guess they’re semi-homemade.

I’ve made chocolate chip cookie bars with cake mix for potlucks, class parties, holidays, and they’re always a hit! They’re the perfect cookies bars for any occasion, and this recipe makes a big batch that’s great for sharing.

Have I mentioned they have chocolate chips? Every bite is a gooey combination of chocolate and yellow cake.

They are easy and fast to make and have just a few ingredients. And look how gooey they are!

  • Cake Mix: One 15-ounce box of yellow cake mix – or use your favorite cake flavor to change it up.
  • Softened unsalted butter: Soft butter helps it mix easier – you can substitute salted if needed
  • Large egg
  • Sweetened condensed milk: Be sure to get a 14 ounce can
  • Chocolate chips: Any size or flavor are fine

  1. Combine the cake mix, egg, and butter in the bowl of a stand mixer fitted with the paddle attachment.
  2. Mix the ingredients until they form a crumbly-looking batter.
  3. Mix in some of the chocolate chips.
  4. Press 2/3 of the batter in the bottom of a prepared 9×13” baking pan. It will be a thin layer.
  5. Pour the sweetened condensed milk over the batter, leaving a 1” border around the edge. Sprinkle the rest of the chocolate chips over the top.
  6. Scoop one tablespoon of the batter and press it between your hands. Lay it on the chocolate chips. Repeat this with the rest of the batter. Try to cover the edges as much as possible, but it’s okay if there are gaps between the pieces in the center of the bars.
  7. Bake the bars at 350°F for 20 to 30 minutes, or until the top is golden brown and milk is bubbling up.
  8. Cool the cookie bars at room temperature, and then chill them until they are set before slicing and serving.

Expert Tips for Making Cake Mix Recipes

  • Don’t forget – you can use any cake flavor that you like for these chocolate chip bars with cake mix. Just be sure to buy a box that is approximately 15 ounces.
  • Using a stand mixer makes it easier and faster to mix the batter. You can use a hand mixer, but it will take longer, so keep mixing until your batter looks like the photo in step two.
  • Beware: condensed or sweetened condensed milk is NOT evaporated milk. Do not substitute one for the other.
  • When you add the condensed milk, be sure to leave a one-inch border around the edge. You want the milk to stay away from the foil – otherwise, it will caramelize and stick to the foil, making it hard to remove the bars.
  • Line your pan with foil and coat it with spray to make it easy to remove the bars in one piece before slicing. Make sure there is some foil overhanging the pan to make it easy to lift the bars out.
  • I know it’s hard to wait, but don’t skip the chilling step. The bars won’t slice nicely unless they are really cold, so be patient, and you’ll be rewarded!

Variations

I’ve already mentioned it, but switching up the cake mix is the easiest way to change the recipe. Oh, the possibilities!

  • You can also use any chocolate chip flavor that you like – try dark chocolate, semi-sweet, milk chocolate, or even white chocolate chips.
  • Or skip the chocolate and use other baking chips like peanut butter or butterscotch.
  • You can also add chopped nuts sprinkles and omit the chocolate if you want.

How to Store Cake Mix Bars (And Freeze Them)

Store the bars in a single layer in an airtight container for up to three days.

You can also freeze them! For best results, store them in layers with paper towels in between each layer. They will keep for up to three months.

Leave them out at room temperature to thaw. The paper towels will absorb the excess moisture, so your bars are perfect when they’re thawed.

Believe me when I say: these are the best cookie bars made with cake mix and sweetened condensed milk!This recipe is always one that gets rave reviews. People love cake mix gooey bars, especially with chocolate. I know you’re going to love them!

Ingredients

  • 1 about 15 ounce box yellow cake mix
  • ½ cup (113g) unsalted butter softened
  • 1 large egg
  • 1 14 ounces can sweetened condensed milk
  • 2 cups (340g) chocolate chips

Instructions

  • Preheat oven to 350°F. Line a 9×13-inch pan with foil and spray well with nonstick cooking spray.
  • Place cake mix, egg, and butter in the bowl of a stand mixer fitted with the paddle attachment. You can also use a hand mixer but it will take longer (just keep mixing!)
  • Press 2/3 of the batter in the bottom of the prepared pan. It will be a thin layer.
  • Top with the can of sweetened condensed milk, leaving a 1-inch border around the edges. If it’s touching the foil it has more chances of bubbling up and/or sticking.
  • Sprinkle chocolate chips over sweetened condensed milk.

  1. Just made the gooey chocolate chip bars. I think the video and written recipe are different. I added all the chocolate chips at once over the condensed milk like the recipe called to do. But the video does it differently Haven’t tasted them yet as they are in fridge chillin

  2. I will never use a store bought cake mix. Do you have a recipe for a cake mix made from scratch? I’m not a great cook so this might be obvious for many but not to me.
    Thank you.

  3. I think add 1 cup as in video then add 1 cup chips after condensed milk, top with last dough. I’m making for Xmas 2018 I’ll do like video.

  4. Extra gooey gooey bars AND they have choc chips?? Obviously I’m all about it!

  5. These look incredible and I have made your gooey bar recipes before…so good. I also just realized I ate a dessert at your house when you hosted the big blogger group, and I can’t remember what it was, but it was so good I wanted to hoard it all. I even made it at home in San Diego…if only I can remember. Getting old lol.
