Nutella Fudge Crumble Bars.
Crumble bars have been an obsession of mine since childhood, and this Nutella fudge version is a new favourite.
As a beginner baker when I was still a child, I remember experimenting with the filling for the iconic Newfoundland favourite Date Crumbles.
Eventually, I tried many different fillings from blueberry to apple to apricot and that experimental inspiration hit me again this week.
Originally, I intended to make a plain chocolate fudge filling for these delicious buttery, crunchy bars. Then, however, I spied a Nutella bottle at the last minute and decided that I just had to add some of that to the mix as well.

Nutella, not just for bread anymore!
The result was amazing! The kids absolutely love them and Spouse, who normally can show great restraint, had more than her fair share too.
We will be making these again and again, I just know it.

I feel like I saw a recipe of yours that was similar to these but chocolate fudge type filling, not Nutella. Am I wrong? I can't eat Nutella but would love to make a chocolate version.

How should I store them? Fridge? Just wrapped on the counter? Any tips?

I store them in a covered container in the fridge but it depends really on how long you want them to last. I usually freeze half the batch.

Hi there, These are cooling as I type:). I just wondered if the butter is unsalted or salted? I never what the rule of them is when it isn't specified. I used unsalted in this first attempt. They smell soooo good!!

That's really a matter of preference. Depends on the brand too...some are too heavily salted for my taste. We always baked with salted butter when I was growing up so I am accustomed to it but there are many times when I have used unsalted for baking. Make sure to never add additional salt if the recipe calls for it when using the salted butter though.
