    Ingredients to make cake mix cookie bars on the counter before mixing together.
    • Yellow Cake Mix: This serves as the base for your cookie bars. Any brand will work just fine! It's basically replacing all the ingredients you need to make cookie dough from scratch. Which means it also saves you time.
    • Large Eggs: Helps bind the mixture together while also adding some moisture.
    • Butter: Use salted butter to enhance the overall flavor. You'll need to melt the butter before combining it with the other ingredients.
    • Vanilla Extract: Vanilla is a universal crowd-pleaser, but feel free to add your desired extract flavor to your cake mixture like almond, coconut, peppermint, lemon, banana, maple, orange, or rum extract instead.
    • Chocolate Chips: We love semi-sweet but you can also use other candies such as chopped peanut butter cups, M&M's, peanut butter chips, chocolate chunks, caramel chips, or your favorite.

    Storage

    Leftovers: These lazy cookie bars will be fresh for up to 5 days when stored in an airtight container at room temperature. Ideally, in a cool, dry place away from direct sunlight and heat.

    If you'd like to keep them longer, consider wrapping them individually and freezing them for up to three months. Just remember to defrost them at room temperature before enjoying them!

    Warm Before Serving: If you want to enjoy them warm, place individual bars on a microwave-safe plate and heat for about 15-20 seconds just until warm.

    What to Serve with Cookie Bars

    Below are tasty options to serve with your Lazy Cookie Bars which can be enjoyed solo, with a beverage, or with other desserts. They're also perfect for parties and potlucks!

    • Hot or cold beverage: Consider a glass of cold milk, a caramel milkshake, Oreo Frappuccino, or a warm cup of tea or coffee.
    • Serve with Cream: Serve with whipped cream or a scoop of vanilla ice cream, hot chocolate ice cream, peanut butter cup ice cream, or your favorite ice cream flavor on the side of a warmed cookie with a drizzle of chocolate, strawberry, or caramel sauce.
    • Other Desserts: You might also enjoy it with an assortment of desserts such as this old fashioned fruit salad, banana pudding brownies, chocolate peanut butter trifle with brownies, chocolate peanut butter poke cake, or S'mores blondies recipe.

    Tips

    Here are some tips to help you master the art of making Lazy Cookie Bars:

    • Ensure your butter is completely melted to avoid lumps in your batter. We usually use our microwave and melt in 25-second intervals, stirring in between each until melted. Then allow it to cool before adding it to your cake mixture.
    • Stir your ingredients gently until just combined. Over-mixing can lead to tough, dense bars. It's fine if your batter has a few lumps in it.
    • Make sure to properly grease your pan with cooking spray or butter to prevent sticking.
    • Spray your spatula or hands with cooking spray when pressing dough into the pan if it's sticking too much.
    • Don't over-bake. Your cookie bars are done when they are slightly golden brown around the edges and a toothpick inserted into the center comes out mostly clean, with a few moist crumbs attached.
    • Allow the bars to cool in the pan. I usually give them about 15 minutes in the pan then transfer them to a wire rack to cool completely.
    • Cool completely before cutting. Cutting the bars while they are still warm may cause them to crumble. Use a sharp knife and be sure to clean the blade between cuts for no sticking and clean edges.
