Kitchen Tools Needed For Loaded Cake Mix Cookie Bars:

How to Make Cake Mix Cookie Bars

To make these delicious cake mix cookie bars, it’s as simple as 1,2,3! 

  1. Use an electric hand mixer to combine your cake mix, eggs, and oil in a large mixing bowl.
  2. Gently stir in your mix-ins including chocolate chips, peanut butter chips, and mini M&M’s.
  3. Spread your batter in a 13×9 Glass Baking Dish with a rubber spatula and bake in the oven until a light golden brown. 

 

Helpful Tips for Spreading Your Batter

The batter for these cake mix cookie bars will be quite thick and it’s a little tricky to spread. 

To make it easier to spread, you should definitely use this rubber spatula.

Because it’s non-stick, it smooths out the batter with ease, unlike using a regular spoon. 

If you don’t have a rubber spatula, the next best option is to use your hands. 

If you use your hands to spread the batter, one little trick is to slightly dampen your hands first, so that it won’t stick to the batter.

Easy Cake Mix Cookie Bars FAQ’s

How to Serve Your Cake Mix Cookie Bars

These cake mix cookie bars are delicious both warm or at room temperature, and can be enjoyed either by themselves or topped with a scoop of your favorite ice cream and a chocolate drizzle. 

 

How to Store Leftover Cake Mix Cookie Bars

Store any leftovers in an airtight container or ziplock bag at room temperature for up to 1 week.

I actually prefer these the next day, as all the flavors taste better, and they’re perfectly soft and chewy. 

 

Can I Freeze Cake Mix Cookie Bars? 

Yes! You can freeze both baked and unbaked cake mix cookie bars.

To freeze baked cookie bars – After you have baked and cooled your bars, place in a freezer safe bag and freeze for up to 3 months. When ready to eat, thaw out on the counter

To freeze unbaked cookie bars – Prepare your batter as directed and place your covered casserole dish straight in the freezer. Once ready to bake, place the cookie bars in your preheated oven and bake for an additional 5 minutes, or until fully baked. 

 

Can I Use A Different Kind of Cake Mix? 

Yes, I prefer using a yellow or white cake mix for a more blondie style bar, but you can definitely use other cake mix flavors to switch it up. Chocolate, Strawberry, or Lemon would all be delicious – especially paired with different mix-ins!
