    Biscoff Toffee Crunch Bars

    Biscoff Toffee Crunch Bars are thick chewy bars filled with the deliciousness of Biscoff butter, chocolate chunks, and crunchy toffee bits. Topped with Biscoff icing these bars are irresistible!

    Two stacks of Biscoff Toffee Crunch Bars filled with chocolate chips.

    Why you'll love this recipe

    • This is a chewy, dense bar full of Biscoff spice flavor and toffee crunch.
    • These bars have  Biscoff icing (that dries beautifully for mailing) sprinkled with toffee bits.
    • The bars maintain their freshness for at least a week

    If you or someone you love is a Biscoff fan, I highly recommend that you bake a pan of Biscoff Toffee Crunch Bars. Drizzle on the icing or spread it over the whole top (it’s that good).

    If nut allergies keep you from using packaged toffee (Heath baking bits) which contains almonds, home made toffee bits are very easy to make. Try my recipe for nut-free toffee bits.

    Instructions

    This is an overview of the instructions. The full instructions are in the recipe card below.

    1. Whisk together the flour, baking powder cinnamon and salt.
    2. In the bowl of an electric mixer, cream together the Biscoff cookie butter, butter, and brown sugar until combined. Add the eggs and vanilla. Beat until fluffy. Mix in the flour mixture until combined.
    3. Stir in the toffee bits and chocolate chips.
    4. Use a spatula to evenly spread the batter into the prepared pan.
    5. Bake for 25-30 minutes or until the top is golden and a toothpick inserted into the middle of the cake comes out clean.

    Storage

    Store bars at room temperature in between layers of wax paper in an air tight container or wrapped in plastic wrap inside an air tight container for up to one week.

    Adapted From: Martha Stewart’s Rocky Ledge Bars

    Ingredients

    Batter

    • 2 ¼ cups all-purpose flour
    • 2 teaspoons baking powder
    • 2 teaspoons cinnamon
    • ½ teaspoon salt
    • ½ cup Biscoff cookie butter smooth or crunchy
    • ¼ cup unsalted butter room temperature
    • 1 ½ cups dark brown sugar packed
    • 3 large eggs
    • 2 teaspoons vanilla extract
    • 1 cup toffee bits
    • 1 cup chocolate chips I used a combination of dark and semi-sweet

    Icing

    • ¼ cup Biscoff cookie butter
    • 2 cups confectioners sugar
    • ¼ cup + 1 tablespoon milk
    • 1 teaspoon vanilla extract
    • ⅓ cup toffee bits

    Instructions

    Bars

    • Preheat oven to 350 degrees F. Using non-stick spray, lightly grease a 9” x 13” baking pan. Line the pan with parchment paper with a 2” overhang on long sides of the pan. Lightly spray over the parchment as well.
    • In a medium bowl, whisk together the flour, baking powder cinnamon and salt.
    • In the bowl of an electric mixer, cream together the Biscoff cookie butter, butter, and brown sugar until combined. Add the eggs and vanilla. Beat until fluffy (about 3 minutes).
    • Mix in the flour mixture until combined.
    • Stir in the toffee bits and chocolate chips.
    • Use a spatula to evenly spread the batter into the prepared pan.
    • Bake for 25-30 minutes or until the top is golden and a toothpick inserted into the middle of the cake comes out clean.
    • Cool in pan for about 20 minutes then run a knife along the edges touching the pan and use the parchment overhangs to lift the bars out of the pan onto a wire rack. Cool completely before icing.

    Icing

    • In the bowl of an electric mixer combine Biscoff cookie butter, confectioners sugar, ¼ cup milk, and vanilla. Beat until smooth. Add additional milk to thin the icing if it is too thick.
    • When ready to ice, remove from refrigerator, remove the parchment and place on top of wax paper on a counter or cutting board.
    • Drizzle or spread icing then immediately sprinkle with toffee bits.
    • Allow icing to set for at least 1 hour, then move onto cutting board and slice.
    • Allow icing to harden completely before storing. Store bars at room temperature in between layers of wax paper in an air tight container or wrapped in plastic wrap inside an air tight container for up to one week.

    Notes

    Packing tips
    Wrap bars individually in plastic wrap then place in an air tight container or zip lock bag for mailing

      Those look incredible! Your description has my mouth watering! I haven't used biscoff in my baking yet but it's been on my radar for a while. Things like this keep me up at night too - sometimes I even dream of recipes.

        Thanks,Reeni! These bars make me very happy. Biscoff seems to work just like a nut butter in recipes. It takes the place of some (or maybe all?) of the butter (or other fat) in the recipe. The flavor is heavenly. 🙂

      These look so chewy and scrumptious! So dangerous to see these at this time of night! The only psychiatric help for foodies like us would be baking or cooking no matter what the time is!

      I do love cookie butter! Occasionally I swirl just a little bit into my oatmeal... haha I just bought a jar of the new crunchy kind Trader Joes started selling too - can't help myself. These sound awesome! And I love that you woke up in the middle of the night with ideas for baking : )

      I wouldn't be able to mail those bars...I'm thinking hiding in a closet munching away sounds like a better idea!!! These look incredible!! I am slightly addicted to the BIscoff spread!!! And waking up in the middle of the night with a baking idea is completely normal 🙂

        Thanks, Jocelyn! I will confess to keeping a secret stash of a few bars before I mailed these off. 🙂 They were for research purposes, of course. I can only bring the Biscoff spread into the house if I am going to use it to bake very soon. Otherwise, I eat the whole jar with a spoon! Glad to hear that my middle of the night baking epiphanies are "completely normal". 🙂

      I might be one of the very few who hasn't even tried cookie butter/Biscoff. Your bars look great - I like the sound of all that texture going on in them.

        I hope you will try them, Monica, and end your lack of Biscoff experience. 🙂 The funny thing is, most of the comments come from people who haven't tried cookie butter/Biscoff yet. I hope to remedy this problem. 🙂 The chewiness of these bars is great!

      I haven't had Biscoff either. I don't know if I could find it here. I live in the country and well, they don't have a lot of stuff I go looking for...lol! These do look amazing and sound amazing! I love that you came up with the recipe yourself. I have the same illness as you, thinking of recipes or things to cook while in bed. Being on my phone on Pinterest before sleep doesn't help...ha!

        Thank you, Suzie. 🙂 I am definitely spoiled with access to cookie butter at Trader Joes and our supermarkets practically at my doorstep. Maybe its not spoiled though. Maybe its just feeding my Biscoff habit. 🙂 Seriously, let me know if I can ever help by mailing you an "exotic" cooking supply. I would be happy to.

        Jess, my friend, this is a warning. You may not want to try Biscoff. It is HIGHLY addictive. You will put it in baked goods. You will eat it with a spoon. You will dream about it. It is the dictionary definition of OMG good. Just a thought. 🙂 Have a great spring break!
