Cake mix cookie bars are the ultimate semi-homemade dessert. These lazy cookie bars are filled with colorful chocolate candy and are always a winner with the kids.
Cake mixes can be used in so many different ways than the recipe on the box. I love using it for cookies like these lemon cookies and strawberry cookies.
Have you ever been invited to a party or gathering last minute and need something quick to make and bring over? Or have your kids shown up with a group of starving friends ready for a snack?
These cookie bars are just the thing to make for these type of situations. Four ingredients, about 30 minutes and you have a treat that everyone will be asking for the recipe.

- Mix: Put cake mix, melted butter and eggs into a large bowl. Mix until combined.
- Stir: Stir candy in with the batter.
- Spread: Spread batter evenly in a 9 x 13 ban lined with parchment paper or foil. The batter is very thick so use a spatula or your hands to get the batter pressed down and spread.
- Bake: Bake cookie bars for about 20 – 25 minutes or until starting to turn golden brown.
- Cool: Make sure to let the bars cool before cutting.
How to store
These will stay good at room temperature in an airtight container. They will last about one week, but mine always get eaten way before that.
To freeze, make sure they completely cool. I like to cut mine into squares and then place them on a baking sheet in the freezer. Once they have frozen, place the squares in a freezer safe container. Thaw in the refrigerator.
Variations
The awesome thing about these cookie bars is that you can use most any candy. I love the colorful M&M’s but here are some other delicious options:
- Chocolate Chips
- White Chocolate Chips
- Butterscotch Chips
- Chopped Heath Bar
- Reeces Pieces (Love this one)
- Butterfinger
Can I use a different cake mix?
Yes, you can use white, chocolate, even red velvet. I prefer the rich vanilla flavor the yellow mix gives these bars.

I followed the recipe to a T. Perfect conditions, turned out as just cake. Fluffy. Airy. Not dense or chewy like anything resembling a cookie. Tasty, but not at all what I was looking for. Would’ve just made regular cake tbh.
