These Nutella Brown Butter Blondies are more than just dessert. They’re a little slice of comfort. I first made them on a rainy afternoon when I needed something cozy and indulgent. Now they’ve become a family favorite. The crackly top gives way to a gooey, rich center swirl with Nutella and browned butter.

Instructions

Preheat the oven to 300℉. Butter a 9×9 pan and line the bottom and 2 sides with parchment leaving an inch or two overhang on each side.

In a medium size bowl mix together flour, baking powder and salt, set aside.

In a large pot over medium heat brown the butter stirring occasionally.

Remove from heat, whisk in brown sugar and vanilla.

Using an electric mixer whip in eggs. Mix on medium high until light and fluffy. It is important that this mixture is well mixed and the color changes from a darker brown to a lighter tan.

Add in the dry ingredients and continue to mix until well mixed and no lumps remain.

Evenly spread batter in prepared pan.

Dollop hazelnut spread by the spoonful evenly across the surface of the batter. Drag a butter knife through the spread to swirl it through the batter. Drag it through again in the opposite direction to swirl more.

Bake for 30-35 minutes in a glass pan, or for 20-25 minutes if using a metal one. The edges will be golden brown and the middle still slightly gooey.

Remove from the oven and allow to cool at least 2 hours before cutting. It is normal for the middle to sink below the edges.

Cut into 16 squares to serve.

Tips & Tricks (5)

Brown Butter to Perfection 🧈
Cook butter over medium heat for 5-7 minutes, swirling occasionally until it turns golden amber with a nutty aroma—don't let it burn. Let it cool slightly before mixing to prevent cooking the eggs.
Nutella Swirl Technique 🌀
Dollop Nutella onto the batter in large spoonfuls rather than mixing it in completely, then use a knife to create ribbons—this prevents over-mixing and ensures gooey pockets throughout.
Underbake for Gooey Centers 🍫
Pull the blondies from the oven when a toothpick inserted in the center still has moist crumbs clinging to it, not clean—they'll continue cooking as they cool and develop that signature fudgy texture.
Cream Room-Temperature Ingredients 🌡️
Ensure eggs and butter are at room temperature before creaming together for 2-3 minutes until pale and fluffy—this incorporates air for a crackly top while keeping the inside dense and chewy.
Line and Cool Properly ✂️
Line your baking pan with parchment paper extending up the sides for easy removal, then let blondies cool in the pan for 15 minutes before cutting—this prevents breaking and allows the structure to set properly.
