How It Comes Together

This recipe is straightforward, and you can expect a delicious outcome with minimal effort. You’ll start by mixing up your wet ingredients and creaming the butters with sugar until fluffy. Next, you’ll add your dry ingredients, along with the fun bits of Golden Oreos and sprinkles. Pour everything into a prepared pan, bake it, and voilà! You have blondies that are sure to be a hit.

What You’ll Need

Gather these items:

3/4 cup unsalted butter (melted)
1/2 cup granulated sugar
1/2 cup brown sugar (packed)
1 large egg (room temperature)
1 large egg yolk (room temperature)
1 teaspoon vanilla extract
1 3/4 cups all-purpose flour
3/4 teaspoon baking powder
1 teaspoon corn starch
1/2 teaspoon salt
10-14 Golden Oreos, plus more to garnish (roughly chopped, divided)
1/4 cup rainbow sprinkles (plus extra for garnish on top)

Helpful Notes

Substitutions: You can use margarine if you don’t have butter, but the taste may vary.
Quality Tips: Using room temperature eggs helps the batter mix evenly.
Why It Matters: Golden Oreos add a delicious twist and provide a fun textural contrast in the blondies.
Optional Add-ins: Feel free to toss in chocolate chips for an extra treat!

Directions to Follow

Preheat your oven to 350°F (175°C). Line an 8×8 or 9×9 inch pan with parchment paper and spray it with cooking spray. Set aside.
In a medium-sized bowl, whisk together the flour, baking powder, and salt. Set it aside.
In a mixing bowl, beat the melted butter and both sugars on high speed for about 2 minutes until light and fluffy.
Add in the egg and egg yolk, one at a time, mixing on medium speed. Be sure to scrape down the sides of the bowl between additions. Add the vanilla extract and mix on low.
Gradually add the dry mixture to the wet ingredients, mixing on low speed just until combined.
Use a rubber spatula to fold in 4 of the chopped Golden Oreos and the sprinkles until evenly distributed.
Pour the batter into the prepared pan and smooth it out with the spatula. Press the remaining chopped Golden Oreos on top and sprinkle more rainbow sprinkles over the surface.
Bake for 25-30 minutes, or until the center is set and the edges are lightly golden brown. A toothpick inserted in the middle should come out clean. Mine took about 28 minutes.

Best Ways to Enjoy It

Birthday Oreo Blondies are perfect on their own, but they can be even better with a few extras. Try serving them warm, topped with a scoop of vanilla ice cream or a dollop of whipped cream. You can sprinkle some additional rainbow sprinkles on top for that festive flair. They’re also great with a cup of coffee or a scoop of your favorite ice cream flavor!

Storage and Reheating Tips

To keep your Birthday Oreo Blondies fresh:

Refrigerator Storage: They can be kept in an airtight container in the fridge for up to a week.
Freezer Guidance: You can freeze them for up to 3 months. Just wrap them well in plastic wrap or foil, then place them in a freezer-safe container.
Reheating Method: When you’re ready to enjoy again, just pop them in the microwave for a few seconds to warm them up.
Food Safety Notes: Always check for any signs of spoilage before consuming.

Helpful Cooking Tips

For the best results with your Birthday Oreo Blondies:

Avoid overmixing after adding the flour; this keeps them chewy.
If you want a richer flavor, brown the butter before mixing it in.
Make sure to not skip the room temperature step for the eggs—they mix better!

Creative Twists

Flavor Swaps: Instead of Golden Oreos, experiment with regular Oreos or chocolate cookies for a different taste.
Dietary Swaps: Use gluten-free all-purpose flour for a gluten-free version.
Add Fruits: Toss in some chopped nuts or even mini chocolate chips for added texture.
