Whether you're a beginner or a seasoned baker, this recipe is simple, fun, and frightfully delicious.

Oreos are an all-time favorite in my house, and I love finding any way to spruce them up into a new dessert to fall in love with them all over again.

Ingredients & Why They Matter

Ingredient	Amount	Why It’s Important
Salted Butter (melted)	½ cup	Adds rich flavor and moisture. Melting it gives the blondies a dense, chewy texture. Salted butter also balances the sweetness.
Brown Sugar	1 cup	Provides sweetness, moisture, and a caramel-like flavor. Essential for a soft, chewy blondie texture.
Eggs (room temp)	2	Bind everything together and provide structure. Room temp eggs mix more evenly and help trap air for better rise.
Vanilla Extract	1 tbsp	Enhances all the other flavors, especially the chocolate and Oreo notes.
All-Purpose Flour	1 cup	The main structure of your blondies. Be sure to measure correctly to avoid dryness.
White Chocolate Chips	½ cup	Add creamy sweetness and contrast beautifully with the Oreos.
Halloween Orange Creme Oreos	16 total	10 are crushed for flavor and texture in the batter; 6 are hand-broken for topping with a spooky effect.
Baking Powder	¼ tsp	Helps the blondies puff up slightly for a soft bite.
Salt	½ tsp	Balances sweetness and sharpens all the other flavors — don’t skip it!

Instructions (with Tips for Every Step)

1. Preheat & Prep

• Preheat your oven to 350°F (175°C).

• Line a 9x9-inch baking pan with parchment paper. Leave an overhang on the sides to easily lift the blondies out later.

  • 🔪 Tip: Grease the pan lightly before adding parchment so it sticks and doesn’t move around.

2. Crush the Oreos

• Crush 10 Oreos using a zip-top bag and rolling pin for a mix of textures, or pulse gently in a blender.

• Break 6 more Oreos by hand into larger chunks. These are for the top; you want them visible and spooky!

  • 👻 Tip: Hand-breaking the topping Oreos gives that perfect chunky Halloween look.

3. Mix the Wet Ingredients

• In a large bowl, combine melted (and slightly cooled) butter with brown sugar. Stir until smooth and glossy.

• Add the eggs and vanilla extract, mixing just until combined.

  • 🧈 Why cooled butter? Too-hot butter can scramble the eggs. Let it sit 5-10 minutes before mixing.

4. Add the Dry Ingredients

• Add flour, baking powder, and salt directly into the wet mixture.

• Fold everything gently with a spatula until no streaks of flour remain.

  • 🚫 Avoid overmixing: Overmixing can cause tough blondies. Stop as soon as the flour is incorporated.

5. Add Mix-ins

• Gently fold in the crushed Oreos and white chocolate chips.

  • 💡 Mix-in tip: Reserve a few white chocolate chips to press into the top for an extra-spooky presentation.

6. Assemble & Bake

• Spread the batter evenly into the prepared pan.

• Press the hand-broken Oreo chunks and extra chips (if any) onto the surface.

• Bake for 30–35 minutes, or until the edges are golden and the center is set but soft.

  • 🔥 Don’t overbake: Blondies will firm up as they cool. A toothpick may still come out with moist crumbs; that’s perfect!

7. Cool & Slice

• Let the blondies cool in the pan for at least 20–30 minutes before lifting them out and slicing.

  • 🎃 For clean cuts: Chill in the fridge for 30 minutes after cooling. Use a sharp knife, wiping it clean between slices.

---

Troubleshooting & Tips

Issue	Likely Cause	Fix
Too dry	Overbaked or too much flour	Check early, and use the spoon-and-level method to measure flour.
Gooey center	Undercooked	Add 3–5 more minutes, or let cool fully to set.
Sinking center	Overmixed or oven door opened early	Fold gently, and keep the oven closed during baking.
Oreos burned on top	Too close to the heating element	Tent with foil halfway through if they’re browning too fast.

🎃 Make It Extra Spooky!

• Drizzle with orange-colored white chocolate or candy melts after baking.

• Add Halloween sprinkles on top before baking.

• Swap in Pumpkin Spice Oreos or Boo Oreos for fun variations.

These spooky Oreo blondies are thick, chewy bars packed with crushed Halloween Orange Creme Oreos and melty white chocolate chips, giving each bite a festive pop of orange and black. Perfectly gooey and hauntingly delicious, they’re a frightfully fun treat for any Halloween party!

Ingredients

• ½ cup Salted Butter (melted)
• 1 cup Brown Sugar
• 2 Eggs (room temperature)
• 1 tbsp Vanilla Extract
• 1 cup of All-Purpose Flour
• 1/2 cup White Chocolate Chips
• 16 Halloween Orange Cream Oreos (10 for filling, 6 for topping)
• ¼ tsp of Baking Powder
• ½ tsp Salt

Instructions

1. Preheat the oven to 350 degrees and line a 9x9 pan with parchment paper.
2. Melt the ½ cup of butter and allow it to cool slightly. While the butter cools, crush 10 of the Oreos to mix in the batter. I use a Ziploc bag and a rolling pin to crush the oreos in a bag to crush them. You can also use a blender or any other method. Set those aside, then take the additional 6 Oreo's and break those by hand to have bigger broken chunks for topping, and set those aside.
3. Add the melted butter and brown sugar to a mixing bowl and mix with a spatula until combined.
4. Add the eggs and vanilla extract and mix until just combined.
5. Use a spatula to scrape down the sides and add the flour, baking powder, and salt. Fold the ingredients together until no clumps of flour remain without overmixing.
6. Next, add the crushed Oreos and white chocolate chips and incorporate them into the dough. Then add the batter to the baking pan. Once in the pan, take the hand-broken Oreo's and place them on the top layer of the blondie mixture throughout the entire top.
7. Bake for 30-35 minutes or until the edges are golden brown. Allow to cool.
