Chocolate-Peanut Butter Cake Mix Cookie Bars
Ingredients:
1 (18.25) package plain yellow cake mix
1/2 cup butter, melted
1 cup creamy peanut butter (I used crunchy- it was amazing)
2 eggs
1 (12 oz) package semi-sweet chocolate chips
1 (14 ounce) can sweetened condensed milk
2 Tablespoons butter
2 teaspoons vanilla
Directions:
1. Preheat oven to 325 degrees. Set aside an ungreased 9X13 inch 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.
These cookie bars are amazing when eaten warm, but are just as good cooled. Serve with a tall glass of milk, and enjoy. You know you want one!

I made these after seeing a recipe for Girl Scout Cookie Tagalong Cake Bars over at Kevin and Amanda. My version is a little different, because I don’t have any Girls Scout cookies.

Chocolate and peanut butter is the best combination of all time. These sound SO good.
Oh yum what a delicious sounding treat, would go really well with the cup of tea I currently have. x
Okay, those look amazing and if I could reach into the computer, they’d be gone. So funny because this is the first year we haven’t had any Girl Scouts trying to sell us cookies either. Probably better for us!
