Prep Time: 5 minutes
Bake Time: 20 minutes
Serves: 16

Ingredients

Told you there were only a few ingredients!

1 package plain yellow cake mix
1/2 cup butter, melted
1 cup creamy peanut butter
2 eggs
1 (12 oz) package semi-sweet chocolate chips
1 (14 oz) can sweetened condensed milk
2 tbsp butter
2 tsp vanilla

Instructions

1. Preheat oven to 325°F. Set aside an ungreased 9″x13″ metal pan.

2. Stir and combine cake mix, melted butter, peanut butter, and eggs in a large bowl using an electric mixer or a wooden spoon. The batter will be thick. Press this into the pan, reserving 1 1/2 cup of the mixture to crumble on top.

3. In a small pot, melt chocolate chips, sweetened condensed milk, and butter. Remove from heat and stir in the vanilla.

4. Spread chocolate mixture over the cookie crust in the pan, and then crumble the 1 1/2 cups of reserved cake mixture on top evenly.

5. Bake for 20-25 minutes. Cool completely before cutting into bars.

Variations

This recipe lends itself well to the bulk section of your grocery store. One reader added M&Ms to the bottom layer of the cake. I have yet to try this but it sounds amazing (and crunchy!). And while I sing the praises of the yellow cake mix, you can replace it with other cake mixes, such as chocolate, devil’s food, or even a flavored cake mix like peanut butter or chocolate fudge. Depending on just how much you love chocolate and peanut butter, you may want to adjust the amount of both if you go with flavored mixes. If you would like a slightly healthier option, use all-natural peanut butter.

FAQs

Can I use crunchy peanut butter?

Yes. In fact, that’s what I used. Totally delicious and provides an enticing texture change.

Can I substitute a different milk for the sweetened condensed stuff?

You could, though I recommend sticking with what the recipe calls for. Doing so delivers the sweetness and texture you’ll enjoy. Evaporated or fat-free milk is thinner and not as sweet. Healthier? Yep. But not as tasty.

Can I scale up the recipe?

Yes, but you may need to extend the cooking time. Use the toothpick test to tell whether it’s done. I would also recommend rotating the pan halfway through baking to ensure it’s done evenly.

These cookie bars will stay soft and chewy, even after they cool. Just make sure that you store them cooled in an airtight container or wrap them individually in plastic or aluminum. If you plan on eating them in a couple of days, store the cookies in a cool, dry place, like a cupboard or pantry. You can refrigerate them to keep them fresh for a few days longer. You can also freeze the cookies. Store them as you would above (you can also place the wrapped cookies inside an airtight container for double the protection) then place them in the freezer, where they should last for up to 3 months. To thaw, move them from the freezer to the fridge, keep them there overnight.

  • I’m making them now. The chocolate filling is to die for. This is my new go to recipe. So easy and I can keep ingredients on hand.

  • I’m not rating this. I had no idea this would have so much chocolate I should’ve read the recipe better before buying and starting to make this. I think the chocolate layer could be reduced by half. For sure not a diabetic friendly cookie bar lol

  • I making these now. It’s the third time. I send them to my son’s job, the guys there love them. I felt peanut butter and chocolate ratio were perfect. The only difference is I used a glass cake because that is all I had, obviously they came out perfect.
