These rich and delicious Nutella oatmeal bars were inspired by my favorite mixed berry bars. I think you will agree that the Nutella is the perfect chocolate layer to be sandwiched between two buttery layers of oats. The absolute best!

These Nutella bars combine my favorite with my favorite: Nutella and oats. I have made these chewy oatmeal bars so many times and every time I make them I think, why would I EVER make any other dessert?

They require only one bowl to make. These are a matter of mix and press--not much else beyond that.

Did I mention there is Nutella involved? Seriously, hooked with one word, that's me. Have them for breakfast with these Nutella Overnight Oats!

Why You Will Love These Nutella Oat Bars:

• It's a ridiculously easy recipe to make. No special equipment required to make these creamy Nutella filled oat bars. Just a medium bowl and a spoon should be all you need aside from the measuring utensils! Stir and then press into a pan. Spread the chocolate hazelnut goodness over top and then add a top layer of oatmeal crumble and you are set!
• Could easily double as a fun sweet breakfast as well as dessert. Oatmeal is a breakfast food right? These are surely a dreamy dessert, but a brunch or fun breakfast spread would be great to add these bars to!
• Requires minimal and simple ingredients. Pantry staples, especially if you are a Nutella lover like me! We always have at least a couple jars on hand. Other than that you just need butter, brown sugar, rolled oats, and flour for the bulk of the recipe.

Recipe Ingredients:

• oats: rolled oats, also known as old-fashioned oats are what you will need for this recipe. I have made this recipe using quick oats and it does work, but I prefer the rolled oats for the best texture in these bars.
• flour: all purpose flour is used in this recipe. You are more than welcome to use a 1:1 gluten free all purpose flour in these Nutella Bars. Use gluten free rolled oats as well in order to keep the entire recipe gluten free.
• butter: I use unsalted butter but you could use salted if preferred. Melted butter but not overly hot.
• brown sugar: I use light brown sugar. You can opt for dark brown sugar but the flavor will be bit more bold
• baking powder: make sure it's fresh!
• salt: we use sea salt in this recipe but table salt is fine
• vanilla: a good vanilla extract will really up the flavor game in these bars!
• Nutella: you can use the name brand Nutella chocolate hazelnut spread but another brand or store brand variation will work as well. You can also technically use almond butter, peanut butter, chocolate almond butter, etc. or another favorite in this recipe instead if preferred!

Step-By-Step Instructions:

• Combine the dry ingredients in a bowl and mix well to combine. (steps 1 and 2)
• Add butter and vanilla to the oat and flour mixture and mix until combined and crumbly texture. (steps 3 and 4)

• Place ⅔ (roughly 2 cups) of the oat crumble mixture into a parchment lined or well greased 8x8 in. baking dish. Reserve ¼ of the mixture and set aside for the top layer. (step 5)
• Press the crumble mixture firmly into the pan. When I say press firmly, I promise you I mean FIRM. This part will make or break whether your bars hold up well and are easily eaten as finger food aside from the crumbles that fall off the top. Get it all in there and use all of your strength. You will thank me later! (step 6)
• Spread Nutella on top of oat layer. Spread it evenly. I go for a nice heaping ½ cup of Nutella most times which creates a good chocolate layer. If you find it does not seem to be enough, going up to about ⅔ cup should still be fine. (step 7)
• Top the Nutella with an even layer of the rest of the crumble mixture. Try your best to evenly distribute this layer. (step 8)
• Bake for about 25-30 minutes or until golden brown top and then allow to cool on a wire rack. If you want really nice cut Nutella bars, chill the bars for a few hours and then cut them. It makes it so much easier and much less mess. You can let them sit out for a bit after that to soften a bit.
