Chocolate Crunchie Slice (no bake)

Are you a fan of Crunchie bars? Then you’re totally going to love this easy no-bake Chocolate Crunchie Slice! Ready in just 10 minutes!

If you’ve been reading Bake Play Smile for a while now, you may have already seen a version of this slice around. In fact, I first made it last year after being given the recipe by a friend. The only problem is that I had just started the blog and literally had no clue when it came to taking photos! I still have no idea and am trying very hard to teach myself, but I’m not quite as terrible as I used to be!

Anyway, it turns out that people love Crunchie bars and every single month this is one of the most popular recipes on the blog. And while I love that people are checking out this yummy recipe, I cringe every single time I see the photos. So here is a revamped version of my Chocolate Crunchie Slice. Yep it’s made with chopped up Crunchie bars so you know it’s going to be insanely good.

This is also a perfect, kid-friendly recipe so grab your kiddies and get them helping out in the kitchen… and if you don’t have any kids then you get to lick the wooden spoon all by yourself!!

This slice is made even more delicious if you add extra chopped up Crunchie bars to the chocolate topping before it sets. BUT!!! If you decide to do this, make sure you’re planning on eating it the same day as otherwise the Crunchies will go all soft and gooey (although you might actually love that!). Because I made this slice the day before I needed it, I decided to just use a chocolate topping instead. Here’s a photo of the same slice I made last year using crushed up Crunchies on top (urgh… please ignore the total and utter awfulness of the photo!).

Yuuuum! My girls love Crunchies so I’m sure this will be a big hit!


My to to is the way easy Mars Bar Slice that everyone knows and loves, it doesn’t last long in my hours and that’s not the kids it’s hubby. It’s is also a great whip up for school cake stall. But this one will be a great change indeed!
And your photography is fine Lucy… I’m not sure what your worried about!

Lauren @ Create Bake Make

We all know you were just looking for any excuse to make this yummy slice 😉 It looks great and your photos are wonderful too x

Rebecca @ Dorm Room Baker

These look delicious! It’s a pity we don’t have Crunchie bars in the States. I wonder if there’s an American equivalent.


The second time I made this with a bag of honeycomb piece I got from the local Poundland and added a little chocolate….just to make sure it was chocolately enough! 😉 it was perfect, this recipe is so easy to make, a big favourite in our house!!x
