Chocolate Hazelnut Oat Bars

Chocolate Hazelnut Oat Bars are sweet, crunchy, and nutty. What a great flavor combination!

Layered bars are a great opportunity to bake something with lots of flavors that complement each other. These bars feature one of my favorite flavor pairs – chocolate and hazelnuts. Combine those with a simple oat crust, and these bars are absolutely delightful!

It all starts with an easy to make crust that’s filled with plenty of oats. You won’t need to get out your mixer for this recipe. You can use a fork or a pastry blender to mix the crust, but I usually just mix it with my fingers. It’s all mixed in one bowl, too, making it even easier.

This type of crust is essentially a shortbread, so it will be pretty crumbly once it’s mixed. If you pinch it together, it should hold together. If it doesn’t, keep mixing for a few more minutes. You can add a little bit of water to help it hold together, but you shouldn’t need to do that if you’ve mixed it sufficiently. Mixing with your fingers, even just for the last bit of mixing, will help. The warmth from your fingers will usually help get it to the finished stage.

After a quick stint in the oven, that crust is then covered in a layer of your favorite chocolate-hazelnut spread. If you like, you can heat the spread for about 10 seconds in the microwave to make it a bit more pourable. But, because it’s spread on top of a freshly baked crust, it will probably warm up enough to make spreading it very easy.

Next comes some of the reserved crust mixture to serve as a crumb topping. Then just sprinkle on some chocolate chips and chopped hazelnuts. A little more baking time, and you’ll have lovely layered treat!

We simply adore these crispy, crunchy, flavor-packed bars! If you’re a fan of chocolate and hazelnuts, then I think you’ll love them, too.
