You are going to LOVE these ooey-gooey super delicious cake mix cookie bars! They are everything you want in a dessert and more.

Most pantries have a box of cake mix, or at least mine does! We have found more tasty ways to use cake mix that is just sitting in your pantry. 

 

While cookies are great, this recipe is an easy bar cookie for a crowd! They take no time to make and you don’t even have to roll the individual balls for the cookies. 

 

Just place the layers and call it good to go! It can’t get much easier than that to make an amazing dessert.

Tools you will need to make these cake mix cookie bars with peanut butter:

  1. 9 x 13 pan (like THIS one)
  2. Spatula 
  3. Large mixing bowl
  4. Microwaveable bowl (I like to use my Pyrex bowls)

 

What ingredients do you need to make white cake mix cookie bars?

 

  • White cake mix box
  • Canola oil
  • Eggs
  • Butter 
  • Milk chocolate chips
  • Peanut butter chips
  • Sweetened condensed milk

 

You can use olive oil instead of canola oil if you choose. However, if you are looking to replace the butter with margarine the bars will not set up as well. 

Start making these amazing cake mix cookie bars WITHOUT pudding mix

To begin, preheat the oven to 350 degrees. 

In a medium-sized mixing bowl, combine together the white cake mix, canola oil, and the eggs. You can use a hand mixer, stand mixer, or you can mix it by hand. 

Then, separate the batter in half. Take one half of the batter and press it evenly into the bottom of a greased 9X13 pan. 

Next, in a small microwaveable bowl, mix together the melted butter, chocolate chips, and peanut butter chips. Microwave everything for 30 seconds and then remove the bowl and stir it well. 

 

Repeat microwaving for 15 seconds and then stir the mixture until it is completely smooth.  

Then, pour in the sweetened condensed milk to the chocolate peanut butter mixture and stir it up until everything is well combined. Now you are going to pour this mixture over the cake mix crust in the 9×13 pan. 

Once you have the first to layers set, take the second half of the cake mix batter and drop it in spoonfuls over top of the chocolate peanut butter layer. 

Now, simply place it in the oven for 20-25 minutes or until the top turns a lovely golden brown. 

 

There is ONE trick to this recipe. You’ll want to make sure this cools completely before serving it to allow the chocolate to set back up.

    Ok, I had issues with this. I mixed up the box of cake mix with the eggs & oil & had trouble getting it to cover the bottom of the 9x13 pan. I ended up having to use a 2nd box of cake mix to put on the top. It looks like a hot mess! It tastes ok & is ooey, gooey but it just does not look right. Any suggestions?

    My family and I don't normally buy boxed cake mixes, but since my husband made a copy cat cake mix batter ice cream and only used 1/2 cup of the yellow cake mix that left us with 12.53 oz that I did not feel right throwing away. With this said I opted to go onto Pinterest and find something to make that my family could all enjoy. Thankfully I came across this recipe despite not having the exact ounce in cake mix nor a 9x13 pan. I was a little worried about the batter not working out, but I went ahead with the recipe so long as nothing else was tweaked i.e. oil and egg's. For those wondering I did used a 9x9 square baking pan that was perfect when it came to spreading my bottom layer of batter evenly. I used peanut butter and milk chocolate morsels that were already combined in one bag vs buying two separate bag's of each. After mixing, prepping, baking and cooling I decided I would then place my finished cookie bars in the fridge for later as a dessert and easier cutting. The cooked bars sat in the fridge for about 2 hours. And since the recipe said it serves 15, which I assume 1 cookie bar per person, I then cut each cookie square at exactly 2 & 1/8 inches - evenly. Having sat in the fridge and finally being able to dig into a bar my family and I can honestly say this recipe was AMAZING. We all loved the bars. So much gooeyness -even after being in the fridge. I opted to half the cooked bars and place some into the freezer for future as despite being a family of 5 we don't always eat sweets as dessert. This recipe is keeper!!! Notes: 9x9 square pan works best Cut each cookie bar 2 & 1/8 in for exact size You can get away with using, at minimum 12.53 ounces of boxed cake mix Still gooey if refrigerated & freezes well

    These cookie bars are DELICIOUS I put hafe on the bottom used my fingers to spread it and it worked great. Then for the top I took some dough and flattened it with my hands and layed it on top it works good that way. If you just put globs on top it won't spread out good. At least it didn't for me. This way worked for me!

      We have not made this with cookie butter. Cookie butter has a much thicker consistency than butter. It's more similar to the texture of peanut butter. I'm not sure where you were thinking to substitute it in. We are huge cookie butter fans. So we would love to hear how it all works out.

    Just made these, and they are mostly still cooling. I love that this was all stuff I already had! I made a double batch with one pan being a 9x13 and then two 8x8 pans. One of the 8x8 pans I put in the freezer for about 20 minutes and they are still a little gooey, but soooooo yummy!! I’m hoping the rest will set up a little harder since they are for a freedom celerbration tomorrow night, but even if they don’t, I know they will be as big of a hit there as they were with my family!
