Gooey, chewy, soft and delicious Double Decker Cookie Bars with even more Chocolate Chips.

So I work with lots of lovely people, and one thing that a couple of girls asked for would be a recipe with Double Decker Bars. I won’t lie, I have never really eaten that many of them… but I LOVE them! Like, why don’t I eat them that often?! I am actually slightly annoyed at myself that I have neglected these so much in the past!

For those of you who don’t know, a Double Decker bar is “Layers of crispy cereal and nougatine wrapped in delicious Cadbury milk chocolate.” according to Cadburys and OHMYDAYS they are so good. It’s a delicious mix up of Toffee Crips Bars, the nougat/fudgey bit of a Mars Bar, and delicious cadburys chocolate for me. Honestly, SO YUMMY.

These delicious treats are based on my Mini Egg Cookie Bars, and my Rolo Cookie Bars and I love these ones just as much. I obviously wanted to fill them with as much Double Decker bits as socially acceptable, but also went for some milk chocolate chips because I love the extra bit of chocolate goo. Genuinely, I find that the chocolate chips helps but the cookie bars when baking, and helps it give an extra element of yum.

I can 100% say that I will be doing more Double Decker recipes now as I am OBSESSED. Honestly, I have eaten so many since I bought these. The recipe is available on my youtube channel, and Rolo my baking mascot puppy does make a very cute appearance! I hope you love these as much as I do! Enjoy! x

This recipe makes 16-25 bars!

Recipe & Method available on youtube!

Tips and Ideas

You could use pretty much any chocolate bar you like, but be careful with any with caramel in for example as it would change how they bake (from all the oozing!)

These delicious beings will last in an airtight container for up to 5 days, but honestly, they’ll be eaten before then.

Try Microwaving them when they’ve cooled if you want a gooey cookie, or even add a scoop of ice cream!

  1. Hi Jane

    I love your recipes and can’t wait to try this one.
    I’d also like to try it with snickers, you mentioned about being careful using bars containing caramel, how should I adjust the baking time if I were to use snickers? Thanks.

    1. Hiya! Yes it might require a couple of minute more baking so keep an eye on it when it gets to the baking time. If it still seems very under done, then add a couple of minutes on! x
