Description

A fudgy, gluten-free brownie infused with Nutella and Japanese sweet potato, topped with a tangy orange glaze. The Nutella swirl adds a gooey center, while the hazelnuts provide a nutty crunch and hint of miso for umami depth.


Ingredients

Scale

1 ½ cups all-purpose flour
¾ cup cocoa powder
2 cups sugar
1 cup unsalted butter, melted
2 large eggs
1 cup Nutella
1 cup hazelnuts, grated into slivers
1 teaspoon baking powder
½ teaspoon salt
1 tablespoon orange zest
¾ cup powdered sugar
2 tablespoons orange juice


Instructions

Preheat oven to 350°F (180°C)
Line an 8×8-inch (20×20 cm) baking dish with parchment paper
Whisk flour, cocoa powder, sugar, baking powder, and salt in a bowl
Add melted butter and eggs, mixing until smooth
Fold in ½ cup Nutella and ½ cup hazelnut slivers
Reserve ½ cup Nutella in a small bowl for swirling
Pour batter into prepared dish, spreading evenly with a spatula
Immediately swirl reserved Nutella into the batter using a toothpick in a spiral pattern
Sprinkle remaining hazelnut slivers on top
Bake for 30 minutes (or until an inch from the edge starts to firm, keeping the center soft)
Let cool completely (at least 2 hours) before cutting into 12 pieces
Whisk orange zest, powdered sugar, and orange juice to create a thin glaze
Drizzle glaze over cooled brownies just before serving

Notes

Toasted hazelnuts develop a richer flavor—ensure they are fully roasted before grating
Swirls look more pronounced when the Nutella is at room temperature
Storage tips: Transfer to an airtight container and refrigerate for up to 5 days
For halal compliance, use certified halal baking ingredients
