Ingredients
Here’s what you’ll need to create these little bites of heaven:
For the Topping (The “Deviled” Part!):
- 1 tablespoon butter, softened: This is our creamy base.
- 2 tablespoons light brown sugar: For a hint of caramel sweetness.
- 1 rounded tablespoon Gochujang chili paste: This is where the magic happens! It adds a fantastic spicy, slightly savory, and sweet kick.
For the Blondies:
- 1 3/4 cups all-purpose flour: The backbone of our blondie.
- 1 teaspoon baking powder: To give them just a touch of lift.
- 1 teaspoon kosher salt: Balances all that sweetness perfectly.
- 3/4 cup granulated white sugar: For classic blondie sweetness.
- 1/2 cup packed light brown sugar: Adds a wonderful chewy texture and deeper flavor.
- 2 large eggs: To bind everything together and give them richness.
- 2 teaspoons pure vanilla extract: Because what’s a blondie without that comforting vanilla hug?
- 2 sticks salted butter, melted and cooled slightly: The key to that incredible chewy, buttery texture.
- 1/2 cup macadamia nuts: For a delightful crunch and buttery flavor. If you’re not a macadamia fan, feel free to swap these out!
How to Make Deviled Blondies
Alright, let’s get baking! This is where the fun really begins.
Prep Your Pan and Oven:
Preheat your oven to 350 degrees F (175 degrees C). Grab a 9×9 inch cake pan. Give it a good grease and then line the bottom with parchment paper. This makes removing the blondies so much easier, and nobody likes a stuck-on dessert!
Whip Up the Topping:
In a small bowl, combine the softened butter, light brown sugar, and that star ingredient, the Gochujang chili paste. Mix it all up until you have a smooth, glorious paste. Set this aside for now – it’s going to be your flavor powerhouse!
Dry Ingredients Together:
In a medium bowl, whisk together your flour, baking powder, and kosher salt. This ensures everything is evenly distributed, so you don’t get any surprise salty or bready bites.
Wet Ingredients Unite:
Now, in a larger bowl, grab your granulated white sugar, packed light brown sugar, eggs, and that lovely vanilla extract. Beat these together with an electric mixer until they’re nice and smooth, looking a bit thick and creamy. Then, pour in your slightly cooled melted butter and beat again until the batter is wonderfully smooth.
Combine and Conquer:
Gently fold your dry flour mixture into the wet ingredients using a spatula. Add in those macadamia nuts. Mix until just combined. We don’t want to overmix here, as that can make blondies tough. A few streaks of flour are okay!
Into the Pan:
Pour your glorious blondie batter into the prepared cake pan. Spread it out evenly with your spatula so you have a nice, flat surface to work with.
The “Deviled” Touch:
Now for the fun part! Dollop your chili topping mixture onto the batter. Aim for about 12 evenly spaced dollops. Grab the tip of a knife and gently swirl each dollop into the batter, creating a beautiful “flame” design. This is what gives them that signature “deviled” look and delicious spicy surprise. It’s a simple touch that makes these stand out! If you’re feeling adventurous, you could even try a fun swirl like those in our blueberry cheesecake swirl rolls, but with this spicy topping!
Bake to Perfection:
Pop the pan into your preheated oven and bake for 30 to 35 minutes. You’ll know they’re ready when a toothpick inserted into the center comes out clean.
Cool and Cut:
Once baked, let them cool completely on a wire rack. This is crucial for getting clean cuts. Patience, my friends! Once cooled, cut them into 9 squares. Enjoy your amazing Deviled Blondies!

Substitutions & Additions
Feeling creative? These blondies are super adaptable!
- Nuts: Don’t have macadamia nuts? Walnuts or pecans would be delicious too! Even chocolate chips would be a fantastic addition.
- Spice Level: If you’re sensitive to spice, start with less Gochujang and add more to taste. If you love heat, you could even add a tiny pinch of cayenne pepper to the batter itself!
- Flavor Boost: A little citrus zest, like orange or lime, added to the batter could give it a brighter note, similar to the zest you find in our blueberry lemon ricotta pancakes.
- For the Chocolate Lovers: Fold in some white chocolate chips or chopped dark chocolate into the batter for an extra layer of decadence.
Tips for Success
A few little tricks to ensure your Deviled Blondies turn out perfectly every time:
- Room Temperature Ingredients: Make sure your butter for the topping is softened and your eggs are at room temperature. This helps everything combine smoothly.
- Don’t Overmix: Seriously, this is key for chewy blondies. Mix just until the ingredients are incorporated.
- Cool Completely: I know, the smell is intoxicating, but letting them cool fully before cutting prevents them from crumbling and ensures clean, beautiful squares.
- Prep Ahead: You can make the chili topping a day in advance and store it in an airtight container in the fridge. Just let it come to room temperature before using. The dry ingredients for the blondies can also be mixed ahead of time and stored in a sealed bag or container.
How to Store Deviled Blondies
These are best enjoyed fresh, but they do store quite well!
- Store cooled blondies in an airtight container at room temperature for up to 3 days.
- If you live in a warm climate or want them to last a bit longer, you can refrigerate them for up to a week. Just let them come to room temperature before serving for the best texture.
- For longer storage, wrap individual blondies tightly in plastic wrap and then place them in a freezer-safe bag or container. They’ll keep in the freezer for up to 3 months. Thaw them overnight in the refrigerator.
FAQs
Q: Can I make these gluten-free?
A: You sure can! Simply swap out the all-purpose flour for a good quality gluten-free all-purpose baking blend. You might need to adjust the liquid slightly, but it’s generally a straightforward swap.
Q: How spicy is Gochujang?
A: Gochujang has a moderate spice level with a nice depth of flavor that isn’t just pure heat. It’s balanced with sweetness and a hint of umami. The amount in this recipe provides a pleasant kick without being overwhelming for most palates. You can always adjust it to your preference!
Q: Can I omit the macadamia nuts?
A: Absolutely! If you’re not a fan of nuts or have allergies, feel free to leave them out. The blondies will still be wonderfully chewy and delicious. You could also add about 1/4 cup of mini chocolate chips instead for a different kind of yummy.
Q: Can I make these ahead of time for a party?
A: Yes! They store well for a few days, so you can bake them a day or two in advance. They are just as delicious, if not more so, as the flavors meld together. Just store them in an airtight container at room temperature.
