2. Ingredients
Gathering high-quality ingredients is the first step to creating these unforgettable hazelnut caramel blondies. Here’s what you’ll need:
- 1 cup (2 sticks) unsalted butter, melted – Using unsalted butter allows you to control the salt level precisely
- 1 ½ cups packed light brown sugar – The molasses in brown sugar creates that signature blondie chewiness
- 2 large eggs, room temperature – Room temperature eggs incorporate better for a uniform texture
- 1 tsp vanilla extract – Pure vanilla extract enhances all the other flavors
- 2 cups all-purpose flour – The foundation of your blondie structure
- ½ tsp salt – Balances the sweetness and enhances flavors
- 1 cup chopped toasted hazelnuts – Toasting brings out their incredible aroma and flavor
- ½ cup caramel sauce – Either store-bought or homemade works beautifully
3. Step-by-Step Instructions
Step 1: Mix the Butter and Sugar
In a large mixing bowl, thoroughly combine the melted butter and packed brown sugar. This crucial first step creates the rich, caramel-like base for your hazelnut caramel blondies. Whisk vigorously for about 2 minutes until the mixture becomes smooth, glossy, and slightly lighter in color. This helps dissolve the sugar crystals which contributes to that perfect blondie texture.
Step 2: Add Eggs and Vanilla
Beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. This gradual addition prevents the batter from separating and ensures your caramel hazelnut blondies will have that ideal chewy texture. After the eggs are well mixed, stir in the vanilla extract. For an extra flavor boost, you could use hazelnut extract instead of or in addition to the vanilla.
Step 3: Fold in Dry Ingredients and Hazelnuts
Gradually add the flour and salt to the wet ingredients, mixing just until the flour disappears. Overmixing develops gluten which can make your homemade hazelnut blondies tough rather than tender. For the hazelnuts, be sure to toast them first to maximize their flavor – simply spread on a baking sheet and toast at 350°F for 8-10 minutes until fragrant. Gently fold in the chopped toasted hazelnuts, reserving a small handful for sprinkling on top if desired.
Step 4: Assemble and Bake
Prepare a 9×13-inch baking pan by lining it with parchment paper or greasing it thoroughly. Pour half the batter into the pan and use an offset spatula to spread it evenly. Warm your caramel sauce slightly so it’s pourable but not hot, then drizzle about half over the first layer of batter. Carefully add the remaining batter on top – it’s okay if some caramel peeks through. Use a knife to create beautiful swirls, then drizzle the remaining caramel over the top. Bake at 350°F (175°C) for 25-30 minutes. The blondies are done when the edges are golden and set but the center still looks slightly underbaked – this ensures maximum chewiness.
4. Serving Suggestions
Allow your caramel blondies with nuts to cool in the pan for at least 30 minutes before cutting – this patience will be rewarded with clean slices. For an elegant presentation, cut into squares and drizzle with additional caramel sauce and a sprinkle of flaky sea salt. These blondies pair wonderfully with coffee or dessert wines. For the ultimate indulgence, serve them warm with a scoop of vanilla bean ice cream and some extra chopped hazelnuts sprinkled on top.
5. Storage Tips
Store leftover hazelnut caramel blondies in an airtight container at room temperature for up to 3 days. For longer storage, they freeze exceptionally well – wrap individual portions in plastic wrap then place in a freezer bag for up to 2 months. To serve, simply thaw at room temperature or warm briefly in the microwave. The caramel will become soft and gooey again, making them taste freshly baked.
6. Recipe Variations
- Chocolate Lovers: Add ½ cup chocolate chips or chunks to the batter, or melt chocolate to drizzle over the cooled blondies
- Nut-Free: Replace hazelnuts with toasted coconut flakes or sunflower seeds for crunch
- Sea Salt Finish: Sprinkle flaky sea salt on top before baking for that perfect sweet-salty contrast
- Espresso Boost: Add 1 tablespoon instant espresso powder to enhance the caramel flavors
- Festive Twist: During holidays, add a teaspoon of cinnamon or pumpkin pie spice to the batter
7. Why This Recipe Works
This quick hazelnut caramel blondies recipe succeeds because of several carefully tested techniques. The high ratio of brown sugar to flour creates that signature chewy texture, while the melted butter (rather than creamed) gives a denser, fudgier result. The layering technique with caramel ensures every bite has that luscious gooeyness without making the blondies soggy. Toasting the hazelnuts beforehand intensifies their flavor and gives them the perfect crunch that contrasts beautifully with the soft blondie base.
8. Frequently Asked Questions
Can I use other nuts? Absolutely! While hazelnuts have a special affinity with caramel, almonds or pecans would also work beautifully. Walnuts would add a more bitter contrast that some prefer.
How do I prevent dry blondies? The key is not overbaking – remove them when the center still looks slightly underdone as they’ll continue cooking from residual heat. Also be sure to measure your flour correctly (spoon and level method) as too much flour is a common cause of dryness.
Can I make these gluten-free? Yes! Substitute a 1:1 gluten-free flour blend for the all-purpose flour. For best results, look for a blend that contains xanthan gum or add ¼ teaspoon xanthan gum per cup of gluten-free flour.
Can I double this recipe? You can certainly double the ingredients, but bake it in two separate pans rather than one larger pan to ensure even baking.
9. Conclusion
