Swirled Nutella Blondies are an irresistible dessert that combines the rich, nutty flavor of blondies with decadent swirls of creamy Nutella.

Baking Tips for Perfect Nutella Blondies

1. Use Room Temperature Ingredients
   Make sure your eggs and butter are at room temperature before mixing. This ensures a smooth batter and even texture.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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

1. Cut with a Hot Knife
   Dip your knife in hot water, wipe it dry, and cut for clean, sharp edges without smudging the swirls.
2. 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.
3. 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.
4. 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.
5. Add Texture with Toppings
   If you're feeling adventurous, top with chopped toasted hazelnuts or chocolate chips before baking. This adds crunch and richness.
6. 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.

What Are Blondies, Anyway?

Blondies are often called the "vanilla version of brownies", but they're so much more than that. They're made without cocoa powder, letting the brown sugar and butter shine. The result is a soft, chewy bar with caramel-like notes — and when paired with Nutella, it's a match made in dessert heaven.

Serve these Swirled Nutella Blondies with:
