Bake: Place the pan in your preheated oven and bake for 20-25 minutes. They should be slightly underbaked for the best chewy texture, so keep a close eye!

Outrageous Chocolate Hazelnut Blondies Recipe FAQs
How do I choose the right hazelnuts for the Outrageous Chocolate Hazelnut Blondies?
When selecting hazelnuts, look for those that are plump, firm, and have a rich, nutty aroma. Avoid any nuts with dark spots or signs of moisture, as they may be stale. If possible, opt for toasted hazelnuts to enhance their flavor; you can toast them at 350°F for 8-10 minutes until fragrant.
What is the best way to store my Outrageous Chocolate Hazelnut Blondies?
Store them in an airtight container at room temperature for up to 5 days for optimal freshness. If you want to keep them longer, refrigerate them for up to 2 weeks. Make sure they’ve cooled completely before storing to prevent moisture buildup.

When you’re ready to enjoy them, simply thaw in the refrigerator overnight or at room temperature for a couple of hours.
What should I do if my blondies are too dry?
If you find that your blondies have turned out dry, it could be due to overbaking. Ensure you check for doneness around the 20-minute mark; they should be slightly underbaked for that chewy texture. Next time, try reducing baking time or adding a little more Nutella to the batter for added moisture.
Are there any allergy considerations with this recipe?
Yes, this recipe contains nuts, specifically hazelnuts, which can be a common allergen. Always check for any nut allergies in those you plan to serve. If you need a nut-free option, you can substitute hazelnut meal with a seed meal, like sunflower seed flour, and ensure that all other ingredients are free of cross-contamination.
What variations can I try with my Outrageous Chocolate Hazelnut Blondies?
Feel free to get creative! You can replace hazelnut meal with almond flour for a different flavor profile or swap Nutella with peanut butter for a fun twist. Adding mix-ins like dried fruit or caramel bits can also bring exciting textures and flavor combinations to your blondies.
