Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

All-purpose flour
Brown sugar
Unsalted butter, melted
Eggs
Vanilla extract
Salt
Baking powder
Nutella (hazelnut spread)

Directions

I preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
In a large bowl, I whisk together melted butter and brown sugar until smooth.
I add the eggs and vanilla extract and mix until fully combined.
I stir in the flour, salt, and baking powder just until no streaks remain—being careful not to overmix.
I pour the batter into the prepared pan and smooth the top.
I drop spoonfuls of Nutella over the batter and use a knife or toothpick to gently swirl it into the top layer.
I bake for 25–30 minutes, or until the edges are golden and a toothpick inserted in the center comes out mostly clean (a few moist crumbs are fine).
I let the blondies cool completely before cutting into squares.

Servings and timing

This recipe makes about 9–12 blondies, depending on how I cut them.
Prep time: 10 minutes
Bake time: 25–30 minutes
Total time: about 40 minutes

Variations

I sometimes mix chocolate chips or chopped hazelnuts into the batter for added texture.
For a salted twist, I sprinkle sea salt flakes on top before baking.
I’ve also used peanut butter or cookie butter in place of Nutella for a fun flavor change.
A drizzle of melted Nutella or chocolate after baking makes them extra decadent.

storage/reheating

I store these blondies in an airtight container at room temperature for up to 4 days.
To keep them extra soft, I sometimes wrap them individually in plastic wrap. They also freeze well—just thaw at room temp or microwave for a few seconds to enjoy warm. Nutella Blondies

FAQs

Can I double this recipe?

Yes, I double the ingredients and bake in a 9×13-inch pan. I usually add 5–10 more minutes to the bake time but still check with a toothpick for doneness.

Do I need to warm the Nutella before swirling?

Not always, but when it’s thick or cold, I microwave it for about 10–15 seconds so it’s easier to swirl.

Can I make these without a mixer?

Definitely. I usually mix everything by hand with a whisk and spatula—no electric mixer needed.

How do I keep blondies soft and chewy?

I take them out when the center still looks slightly underbaked and let them finish setting in the pan as they cool. That gives me the perfect chewy texture.

Can I use light brown sugar instead of dark?

Yes, both work well. I prefer dark brown sugar for a richer flavor, but light brown sugar still gives great results.

Conclusion

Nutella Blondies are one of those simple, satisfying treats that always hit the spot. I love how easy they are to throw together and how the Nutella swirl turns each square into a little piece of dessert heaven. Whether I’m baking for others or just for myself, these chewy bars never disappoint.
