Ingredients

- Nutella: The star ingredient for gooey, chocolate-hazelnut swirls. Make sure it’s at room temperature so it’s easy to swirl into the batter.
- Light Brown Sugar: Adds moisture and a rich, caramel-like flavor. Be sure to firmly pack the sugar when measuring for the best texture.
- Butter: Brings a tender, rich base to the blondies. Use unsalted so you can control the saltiness, and melt it gently.
- All-Purpose Flour: Provides structure to the blondies. Measure correctly by spooning flour into the cup and level it off to avoid a dense texture.

- Add-Ins: Fold in chopped nuts or dried cherries to add texture and extra bursts of flavor.
How to Make Nutella Blondies
These Nutella swirl blondies are quick, easy, and always a hit. Start by preheating the oven to 350°F and greasing a 9″ cast-iron wedge pan or skillet with nonstick spray so your blondies come out of the pan easily.

Step 1: Mix the Wet Ingredients. Whisk together the light brown sugar, melted butter, beaten egg, and vanilla extract until smooth and creamy.

Step 2: Combine the Dry Ingredients. Whisk together the all-purpose flour, baking powder, and salt in a separate bowl.

Step 3: Blend the Batter. Gradually add the dry ingredients to the wet ingredients, stirring until fully combined and a smooth batter forms.

Step 4: Add the Nutella. Spoon the batter into the prepared pan, then drop teaspoons of Nutella on top.

Step 5: Swirl It. Use a toothpick to swirl the Nutella gently into the batter.

Step 6: Bake and Cool. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let cool slightly before slicing, then serve warm for a sweet family treat, perfect after enjoying a hearty meal like my easy beef stroganoff.
Expert Tips
- Use Room Temperature Ingredients: Make sure the egg and butter are at room temperature to help the batter mix smoothly and prevent lumps.
- Don’t Overmix: Stir the batter until just combined, as overmixing can make the blondies tough instead of soft and fudgy.
- Swirl, Don’t Mix: Drop the Nutella in spoonfuls and swirl gently with a toothpick. Swirling too much can cause the Nutella to sink or blend completely, losing that fun swirl effect.
- Storage: Store leftover blondies in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. Reheat briefly for a warm, gooey treat.

Serving Suggestions
- Enjoy Nutella blondies warm as a dessert after a weeknight dinner, like alongside my chicken pot pie or bacon cheeseburger casserole.
- Pair them with a cup of coffee or hot chocolate for a cozy afternoon snack with friends, and serve them alongside my oatmeal chocolate chip cookies.
- Bring these Nutella treats to parties or potlucks, cut into small squares, where they’re easy to share and always disappear fast.
Nutella Blondies Recipe FAQs
You can mix the batter and keep it in the fridge for up to 24 hours before baking. Just let it sit at room temperature for 10–15 minutes before baking so it bakes evenly.
Avoid overbaking and check with a toothpick at the 25-minute mark. The center should be almost set when the blondies are ready.
A 9-inch metal or glass baking pan works fine, though baking times may vary slightly; start checking a couple of minutes earlier.
