How to Melt Caramels

There are few ways you can make a caramel sauce for cookies and/or ice cream topping.

You can make a simple caramel recipe and cook it just under the softball stage, you can purchase pre-made caramel sauce, (Mrs. Richardson's caramel sauce is the best for this recipe. It's smooth, creamy and has a perfect consistency) or you can melt down some wrapped caramel candy.

For this recipe, I melted down some caramel candy. It was easy, it only took a few minutes, and turned out perfect for this cookie bar recipe.

The first thing you will want to do is unwrap the caramels. Add them to a microwave safe bowl, add 1 teaspoon of evaporated milk and melt the caramels on 50% heat for 1 minute. Stir the caramels.

Be sure to stir the caramels every time you melt them in the microwave. Some caramels retain their shape even though they are melted. You also want to incorporate the evaporated milk in with the caramel.

Cook for 30 seconds on 50% heat and stir, repeat 4-6 times or until the caramel is smooth and all melted.

This cookie bar recipe has a few steps but each one of the steps is easy and only takes a few minutes. The result is these incredible Caramel Peanut Butter Cookie Bars. One of the best cookie bar recipes of all time!

Oatmeal cookie bar recipe: This cookie bar recipe has oatmeal, flour, butter, and sugar... the perfect combo! You are only going to use about ¾ of the recipe on the bottom of the cookie sheet. You will save the last ¼ oatmeal cookie bar recipe for the crumble topping after you've added all the other ingredients. Bake for 13 minutes.
Peanut butter mixture: This is a simple mixture, only 2 ingredients. Add the white chocolate chips to a microwave safe bowl, melt on 50% power, stir, and repeat for 4-6 cycles or until the white chocolate chips are melted. (You can also substitute the white chocolate chips for regular milk chocolate chips in this cookie bar recipe. Add the peanut butter to the melted chocolate chips and stir until smooth.
Caramel Sauce: I added the instructions to the caramel sauce recipe above, or you can use the Mrs. Richardsons caramel sauce which turns out amazing every time.
Add the chocolate chips. I like to use Guittard Chocolate chips because they are BIG. For whatever reason, it's really fun to have huge chocolate chips in this Peanut Butter Caramel Cookie Bar Recipe.
Add the remaining oatmeal cookie bar recipe to the top of the cookie bars and bake for an additional 15 minutes. It makes a delicious crumble topping!
Bake for another 8-10 minutes or until it is just golden on the edges.
