    Enjoy these delicious chocolate magic bars with a cookie cake base topped with caramel, peanuts, Reese's Pieces, and chocolate peanut butter glaze. These gooey magic bars are quick and easy to make for Halloween, a bake sale, or dessert tonight.

    Magic bar recipes are super easy. You just layer ingredients in a pan and bake.

    I love baking them for Halloween. My Halloween Cookies and Cream Magic Bars made with OREO Cookies and chocolate chips and Candy Corn Magic Bars made with Nutter Butter Cookies and candy corn were so popular that I thought I'm try a new combination of ingredients.

    Today, I'm sharing my recipe to make decadent Chocolate, Caramel, and Peanut Butter Magic Bars. Each ooey gooey bar starts with a layer of chocolate cake and is topped with caramelized sweetened condensed milk, lots of peanuts, and chocolate chips.

    A closeup of magic cookie bars with layers of chocolate cookie cake, peanuts, caramel, Reese's Pieces, and chocolate peanut butter glaze.

    To give the bars a robust peanut butter flavor, I sprinkled on Reese's Pieces, but I only used the orange candies to make my bars magical for Halloween. If you make them any other time of year, you can use the yellow and brown ones too.

    Then, I drizzled some chocolate peanut butter sauce over top to make the bars even more amazing!

    So, let's bake some layer bars.

    Ingredients

    Devil's Food Cake Mix and the ingredients listed on the box (eggs and oil)
    peanuts - I used roasted and salted peanuts.
    sweetened condensed milk - This will caramelize while baking turning into gooey caramel.
    semi-sweet chocolate chips - Use your favorite brand. I love Hershey's Special Dark.
    orange Reese's Pieces (or orange M&M's)
    creamy peanut butter - You'll mix this with chocolate to make a delicious chocolate peanut butter glaze to drizzle over the bars.

    Supplies

    9 by 13-inch baking pan
    non-stick aluminum foil or parchment paper

    Instructions

    Step 1 - Prep the pan.

    Preheat your oven to 350 degrees Fahrenheit (325 for dark or non-stick pans)

    Line a 9-inch by 13-inch baking pan with non-stick aluminum foil or parchment paper. This will make removing the bars so much easier! The gooey caramelized sweetened condensed milk will be very sticky.

    Pouring sweet and condensed milk over a layer of cake mix and peanuts and adding chocolate chips.
    Orange Reese's Pieces layered on top of chocolate chips, sweet and condensed milk, peanuts, and a layer of chocolate cookie cake in a 9 by 13 pan.

    Step 2- Layer the ingredients.

    1. Stir together cake mix, egg, and oil until well combined. Press it into an even layer in the bottom of the baking pan.
    2. Sprinkle peanuts on top.
    3. Pour sweetened condensed milk over top.
    4. Sprinkle on chocolate chips.
    5. Bake for 25 minutes. Remove from oven and sprinkle on orange Reese's Pieces.
    6. Bake for 5-8 more minutes until the sweetened condensed milk caramelizes and turns golden brown. The edges of the bars should look set. The center will still jiggle a bit but should firm up as it cools.
    stirring melted chocolate and peanut butter together to make a glaze.
    Drizzling chocolate peanut butter glaze over Reese's pieces topped magic bars.

    Step 3 - Make the glaze and drizzle it over the bars.

    1. Allow the magic bars to cool completely.
    2. Cut into squares.
    3. Pour ¼ cup chocolate chips and ¼ cup peanut butter into a microwave-safe bowl.
    4. Heat on high for 20-second increments, stirring after each until melted.
    5. Drizzle peanut butter chocolate glaze over the top of the bars, allowing it to drip over the sides of your bars.

    Storage

    Serve or keep stored in an airtight container for up to 4 days.

    You can wait to drizzle on the glaze until you eat the bars. It tastes great warm.

    Variations

    The beauty of magic bars, also known as, layer bars is that you can layer just about any ingredients on top of a crust and a layer of sweetened condensed milk.

    Halloween magic bars with an OREO Cookie crust, caramel, chocolate chips, orange chips, and cookie pieces.

    You can make Halloween Magic Bars with an OREO Cookie layer topped with caramelized sweetened condensed milk, chocolate chips, orange chips, and OREO cookie pieces.
