Why It Works Every Time

The beauty of Nutella Stuffed Brownies lies in the balance of flavors and textures. The semi-sweet chocolate creates a deep, rich base, while the Nutella adds a delightful creaminess that contrasts perfectly. The addition of cornstarch ensures a chewy texture, and the chocolate chips elevate the chocolate experience. When baked, the Nutella forms a luscious center that melts in your mouth, making each bite a chocolate lover’s dream.
The Ingredient Lineup
To create these delectable brownies, gather the following ingredients:
- 1 (13 oz) jar Nutella – The star of the show, this hazelnut spread adds that signature creamy goodness.
- 4 tablespoons unsalted butter – For richness and depth of flavor.
- 8 ounces semi-sweet chocolate – I used 2 bars of Ghirardelli 60% bittersweet chocolate baking bars for a rich taste.
- ½ cup vegetable oil – Helps to create a moist texture in the brownies.
- 1 ½ cups powdered sugar, sifted – Sweetens the brownies without making them too dense.
- 2 eggs plus 1 egg yolk – Provides structure and richness.
- 1 teaspoon vanilla extract – Enhances the chocolate flavor.
- ½ cup all-purpose flour – The base for the brownie structure.
- 1 tablespoon cornstarch – Keeps the brownies chewy and soft.
- ½ teaspoon salt – Balances the sweetness.
- ½ cup chocolate chips – Adds extra chocolatey goodness.
Equipment Breakdown
Before you start baking, make sure you have the following tools on hand:
- 8×8 inch baking pan – Perfect for creating the ideal thickness for brownies.
- Mixing bowls – For combining ingredients.
- Whisk – Ensures a well-mixed batter.
- Spatula – For folding in the Nutella and chocolate chips.
- Measuring cups and spoons – Accurate measurements are key to success.

Mastering Nutella Stuffed Brownies: How-To

Follow these simple steps to create your Nutella Stuffed Brownies:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease your 8×8 inch baking pan or line it with parchment paper for easy removal of the brownies later.
Step 2: Melt the Chocolate and Butter
In a microwave-safe bowl, combine the unsalted butter and semi-sweet chocolate. Microwave in 30-second intervals, stirring in between, until fully melted and smooth.
Step 3: Mix in Oils and Sugars
Once the chocolate mixture is cool to the touch, mix in the vegetable oil and sifted powdered sugar. Whisk until well combined and smooth.
Step 4: Add Eggs and Vanilla
Add the eggs and egg yolk one at a time, whisking well after each addition. Stir in the vanilla extract until fully incorporated.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, cornstarch, salt, and chocolate chips. Gradually fold this mixture into the wet ingredients until just combined. Be careful not to overmix!
Step 6: Layer the Batter
Pour half of the brownie batter into the prepared pan, smoothing it out evenly. Next, dollop the Nutella over the batter, creating a nice line down the center. Use a spatula or knife to swirl the Nutella slightly into the batter.
Step 7: Top with Remaining Batter
Pour the remaining brownie batter over the Nutella layer, ensuring it is covered completely. You can use the spatula to smooth the top if needed.
Step 8: Bake
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Be careful not to overbake, as you want that fudgy texture!
Step 9: Cool and Slice
Allow the brownies to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Once cooled, slice into squares and enjoy!
What to Use Instead

If you need to make substitutions, here are some options:
- Nutella – Use any hazelnut spread of your choice.
- Vegetable oil – Can be replaced with melted coconut oil or melted ghee for a different flavor.
- Semi-sweet chocolate – Dark chocolate or milk chocolate can be used depending on your sweetness preference.
- All-purpose flour – Gluten-free flour blends work well for a gluten-free version.
Pitfalls & How to Prevent Them
To ensure your Nutella Stuffed Brownies turn out perfectly, keep these tips in mind:
- Don’t overmix the batter – This can lead to dense brownies. Mix just until combined.
- Check for doneness – Ovens vary, so check your brownies a few minutes before the suggested time.
- Cool completely before slicing – This helps the brownies set and makes them easier to cut.
- Use high-quality chocolate – This greatly enhances the flavor of your brownies.
Best Ways to Store
To keep your Nutella Stuffed Brownies fresh and delicious, follow these storage tips:
- Room Temperature – Store in an airtight container for up to 3 days.
- Refrigeration – These brownies can be kept in the fridge for up to a week.
- Freezing – Wrap individual brownies tightly in plastic wrap, then place in a freezer bag for up to 3 months. Thaw at room temperature when ready to enjoy!
Helpful Q&A

Absolutely! Milk chocolate will add a sweeter flavor to your brownies, so adjust the sugar if needed.
What should I do if my brownies are too gooey in the center?
If your brownies seem underbaked, return them to the oven for an additional 5 minutes. Keep an eye on them to avoid overbaking.
