Description
A chocolate lover’s dream, combining a dense, cocoa-rich base with thick ribbons of creamy hazelnut spread. These brownies feature a sophisticated glossy, crackly top and a decadently moist interior. Every bite is marbled with extra Nutella for a perfect balance of deep chocolate and toasted hazelnut.
Ingredients
The Brownie Base
- 1/2 cup unsalted butter
- 2/3 cup granulated sugar
- 2 large eggs, room temperature
- 2/3 cup Nutella (for the batter)
- 3/4 cup all-purpose flour
- 1/4 cup Dutch process cocoa
- 1 tsp vanilla, 1/2 tsp salt
The Swirl
- 1/3 cup Nutella (reserved for top)
Instructions
Prep: Preheat oven to 350°F. Line an 8×8 pan with parchment.
Glossy Base: Microwave butter and sugar in 30s intervals (3 total), whisking between. Whisk until glossy.
Emulsify: Whisk in eggs one at a time for 2 mins until lightened. Stir in 2/3 cup Nutella and vanilla.
Fold: Gently fold in flour, cocoa, and salt until just incorporated.
Swirl: Pour batter into pan. Dot with remaining Nutella and swirl 3–4 times with a knife.
Bake: Bake for ~30 mins until edges are set but center has a slight wobble. Cool completely.
Notes
The Shiny Top Secret: Repeatedly whisking and heating butter and sugar creates the tissue-thin, crackly crust.
Dutch Process Cocoa: Provides a darker, richer color and less acidic flavor than natural cocoa.
Less is More: Limit swirling to 3–4 passes to keep the Nutella in thick, distinct ribbons rather than blending it into the batter.
