Ingredients
Instructions
-
Start by preheating your oven to 350°F (175°C). Lightly grease an 8x8-inch square baking pan or line it with parchment paper for easy removal.
-
In a mixing bowl, combine the melted butter and brown sugar. Stir until the mixture is smooth and glossy. Add the egg and vanilla extract, whisking until fully incorporated. Now, add the flour and salt (and baking powder if using). Stir until just combined — be careful not to overmix, or the blondies may become tough.
-
Pour the batter into the prepared pan and spread it evenly with a spatula. Warm the Nutella slightly (10–15 seconds in the microwave) to make it easier to swirl. Drop spoonfuls of Nutella across the top of the batter, then use a knife or toothpick to gently swirl it into the blondie batter in a marbled pattern.
-
Bake for 22–28 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out with moist crumbs (not wet batter). If you prefer gooier blondies, aim for the lower end of the baking time.
-
Let the blondies cool in the pan for at least 20 minutes before slicing. This allows them to firm up and makes cutting cleaner. Slice into squares or rectangles as desired.

Baking Tips for Perfect Nutella Blondies
- Use Room Temperature Ingredients
Make sure your eggs and butter are at room temperature before mixing. This ensures a smooth batter and even texture. - Don’t Overmix the Batter
Once you add flour, mix gently just until combined. Overmixing can lead to dense blondies instead of soft, chewy ones. - Line Your Pan with Parchment Paper
This makes it easy to lift the blondies out of the pan for clean slicing and keeps the edges from sticking. - Melted Butter Adds Fudgy Texture
Unlike cookies, melted butter in blondies creates a rich, chewy base. You can also brown the butter slightly for added flavor depth. - Use Quality Nutella (or Similar Spread)
Good-quality hazelnut spread melts and swirls better. Warm it slightly in the microwave (10–15 seconds) to make it easier to drizzle and swirl. - Swirl Strategically
After pouring the blondie batter into the pan, dollop Nutella on top in small spoonfuls, then use a knife or skewer to gently swirl it. Avoid over-swirl—too much mixing will muddy the contrast and ruin the marbled effect. - Don't Overbake
The blondies continue to cook slightly as they cool. Take them out when the center is just set and edges are lightly golden. A toothpick inserted should come out with a few moist crumbs (not wet batter).
Serving Tricks to Impress
- Cut with a Hot Knife
Dip your knife in hot water, wipe it dry, and cut for clean, sharp edges without smudging the swirls. - Top with a Sprinkle of Sea Salt
A light sprinkle of flaky sea salt just before serving balances the sweetness and enhances the Nutella flavor. - Serve with Ice Cream
Warm Nutella blondies topped with a scoop of vanilla bean or hazelnut ice cream? Absolute heaven! Drizzle a bit more warm Nutella or chocolate sauce on top for a next-level dessert. - Mini Blondie Bites for Parties
Bake them in a mini muffin tin or cut them into tiny squares and skewer them with toothpicks for a bite-sized treat that's perfect for dessert platters or holiday trays. - Add Texture with Toppings
If you're feeling adventurous, top with chopped toasted hazelnuts or chocolate chips before baking. This adds crunch and richness. - Serve with Coffee or Espresso
These sweet treats pair beautifully with strong coffee or espresso, making them ideal for afternoon tea or brunch tables.
Servings & Storage Tips
- Standard Recipe Yields: 12–16 squares (in an 8x8-inch pan)
- Make Ahead: Nutella blondies can be made a day in advance. The flavor often improves as they sit.
- Storage: Store in an airtight container at room temperature for up to 4 days. For longer storage, freeze them for up to 2 months—just wrap tightly in plastic and foil.
Tips for Perfect Swirled Blondies
- Don't overbake. Blondies continue to cook slightly in the pan as they cool. Remove them when the center is still soft but set.
- Room-temperature egg mixes more easily with the butter and sugar, leading to a smoother batter.
- Customize it! Add a handful of chopped hazelnuts, chocolate chips, or sea salt flakes on top for extra flair.
- Double the recipe and bake in a 9x13-inch pan if you're serving a crowd.
Storage & Make-Ahead

- Freezer-friendly: Freeze individual bars wrapped in plastic wrap and placed in a freezer-safe bag or container for up to 2 months.
- To enjoy later, simply thaw at room temperature or microwave for a few seconds to bring back the gooey goodness.

Frequently Asked Questions
What are Nutella Blondies made of?
Nutella Blondies are chewy dessert bars made with a rich vanilla blondie batter swirled with creamy Nutella. The base typically includes ingredients like melted butter, brown sugar, eggs, vanilla extract, flour, and a pinch of salt.
The Nutella is dolloped and swirled into the batter before baking, creating a beautiful marbled effect and a nutty, chocolate-hazelnut flavor in every bite.
How do I swirl Nutella properly into the blondie batter?
For perfect swirls, slightly warm the Nutella so it’s easier to spread. After pouring the blondie batter into the pan, drop spoonfuls of Nutella over the top.
Use a knife or skewer to gently swirl it through the batter in a figure-eight motion. Be careful not to overmix—swirl just enough to create a marbled look without blending the Nutella fully into the batter.
Can I make Nutella Blondies ahead of time?
Yes! Nutella blondies are great for make-ahead treats. You can bake them up to 2 days in advance and store them in an airtight container at room temperature.
They also freeze well—wrap tightly in plastic and store in a freezer bag for up to 2 months. Just thaw at room temperature before serving.
How do I know when the blondies are fully baked?
Bake at 350°F (175°C) for 20–25 minutes or until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
Avoid overbaking—they continue to firm up as they cool. The center should be slightly soft but set. Cool before slicing to get clean, neat squares.
