These brown butter Nutella blondies are simple blondies elevated with brown butter and Nutella! The simple dough comes together in one bowl. Then, Nutella is dolloped and swirled between the two layers. So much perfect chocolate-hazelnut goodness!
I am a huge Nutella fan, and after making my Oatmeal Nutella Stuffed Chocolate Chip Cookies I knew I had to make some sort of blondie with Nutella soon.
Now this recipe uses brown butter. It is a game changer! Transforming butter into browned butter is simple but makes such an amazing impact on your brownies. It only requires one ingredient too: butter!
These Nutella bars are the ultimate cookie bar for any Nutella lover. If you love Nutella (who doesn’t!?) this one is for you.
Why this recipe works
Easy to make – No mixer required, one bowl, and simple ingredients you can find in your pantry.
Gooey: There is Nutella dolloped inside these bars! Making them ridiculously gooey and chocolatey!
Nutella fans: If you are a fan of Nutella or chocolate hazelnut goodness, you are going to go crazy over these bars!

Butter – I always use unsalted butter. This will be melted and browned.
Dark brown sugar – This sugar carries more molasses than golden brown or light yellow sugar, which deepens the brown butter flavours. You may use any type of brown sugar.
Nutella – You can use actual Nutella or a store brand version.
Step by step instructions
Step 1 – Prep. Grease the pan. For easy removal of the brownies, place parchment paper on the bottom and 2 sides of the pan. Grease again and then set aside. Brown the butter (see recipe card below for details). While it cools, prep the rest of your ingredients.
Step 2 – Whisk the butter and sugar. In a large bowl, whisk the melted and cooled brown butter and dark brown sugar until well combined.
Step 3 – Add the wet ingredients. Add the eggs and vanilla. Continue whisking for another minute or so.
Step 4 – Fold in the dry ingredients. With a rubber spatula, fold in the flour, baking soda, and salt.
Step 5 – Press the dough into the pan. Evenly press 3/4’s of the dough into the prepared baking pan.
Step 6 – Add the Nutella layer. Dollop tablespoon’s of Nutella on top of the dough. Then take the remaining dough and place it on top. It’s okay if there is Nutella peeping through!
Step 7 – Bake. Bake the bars for 25-35 minutes. The bars will look golden brown on the edge but slightly puffy in the middle. Let the bars cool before cutting and enjoy!
Expert Baking Tips
Here are a few expert baking tips from my kitchen to yours
- Use a gram scale for the most accurate measurements.
- Cool the brown butter for at least 20 minutes before using it. You can speed up the process by pouring it into a bowl and placing it in the fridge. I like to make the brown butter first so it cools as I prep the rest of my ingredients!
- Don’t over bake the bars. Pull the pan out of the oven when the edges are light golden brown but the middle is still soft and slightly puffy.
- Cooling time. The bars must cool completely if you want them to slice well! I prefer mine warm, which can get messy..but messy is good!
Can I use something other than Nutella?
If you’re not a fan of Nutella, you can use peanut butter or another nut butter.
Do I have to brown the butter?
No, but if you are already melting it, why not brown it! It elevates this recipe big time.
Storing and freezing
Store the blondies at room temperature in an air-tight container or ziplock bag for up to 5 days.
Freeze the blondies for up to 30 days. Warm up to thaw.

Brown Butter Nutella Blondies
- Preheat the oven to 350℉/180℃. Grease an 8×8 inch square pan. For easy removal of the blondies, place parchment paper on the bottom and 2 sides of the pan. Grease again and then set side.
- Brown the butter: Melt the butter in a medium sized pan over medium heat. Once it melts, it will crackle, then become foamy – continue mixing the butter while this happens to prevent burning. The butter will go from melted to golden brown quickly, and you'll know it's almost done when the aroma of browned butter arrives. The whole process should take about 5 minutes! Once golden, remove from heat and transfer to a glass bowl.3/4 cups butter
- In a large bowl, mix together the browned butter and brown sugar.1 1/4 cups dark brown sugar
- Add in eggs and vanilla and continue whisking.2 eggs, 1 tbsp vanilla
- Add in flour, baking soda, and salt. Using a spatula, gently fold until a soft dough forms. Don't overmix!2 cups all-purpose flour, 1/2 tsp salt, 1/2 tsp baking soda
- Into your prepared pan, add 3/4's of the dough. Press down firmly into the bottom of your pan.
- Scoop Nutella onto the base and spread into an even layer. Make sure there is about a 1-2 cm edge all around. This helps ensure your Nutella does not burn on the edges while baking.3/4 cups Nutella
- Press the remainder dough on top of the bars. It's ok if some Nutella is showing through.
- Bake for about 25-35 minutes until the edges are golden and the middle feels almost set. Cool before slicing.
- My favourite way to eat these blondies is warm! Sometimes it can get messy but it is so worth it! Enjoy!
