Matcha Oreo Blondies

Matcha Oreo blondies are fudgy, chewy, and buttery like classic blondies. The combination of earthy matcha powder and dark cocoa Oreos are hard to pass!

This matcha blondie recipe is also super easy to make!

What are blondies?

Blondies are fudgy and rich cookie squares. The texture is similar to that of fudge brownies, but they don't have any melted chocolate or cocoa powder in the batter.

They may have chocolate chips as mix-ins, but the main flavors are vanilla and brown sugar.

Matcha Oreo Blondies

Matcha oreo blondies are the perfect Japanese and American fusion dessert! They're made just like classic blondies, but with matcha powder and crushed Oreo cookies mixed into the batter.

I originally developed this matcha blondie recipe in 2016 using matcha Oreos that I found in Japan. I've since made them using regular Oreos as well as gluten-free Oreos, and both work perfectly!

Matcha Blondies Ingredients

• Flour - I use all purpose in this recipe. If you're making them gluten-free, mix gluten-free all-purpose flour and almond flour.
• Salt - All desserts need a little salt to bring out the flavors of the ingredients and balance out the sweetness.
• Baking powder - I only add a little to this matcha blondie recipe, but it's enough to add a little lift.
• Matcha powder - Make sure you're using pure matcha powder, and the best quality you can get your hands on.
• Butter - Use unsalted butter so you have full control over the amount of salt in this recipe. Substitute with vegan butter to make this recipe dairy-free.
• Light brown sugar - If you can't find light brown sugar, you can combine granulated sugar and dark brown sugar at a 1:1 ratio.
• Egg - Use a large egg to add the perfect amount of moisture to the matcha blondies.
• Egg yolk - The extra egg yolk adds moisture and richness to the blondies.
• Vanilla extract - Make sure to use pure vanilla extract, and not artificial flavoring.
• Crushed Oreos - Don't crush them too finely because it'll muddy the color of the batter.

How to make matcha oreo blondies

1. Preheat the oven to 350°F/180°C, and line an 8-inch square pan with parchment paper and set aside.
2. In a small bowl, combine the all-purpose flour, salt, baking powder, and matcha powder.
3. In a separate bowl, stir together the melted butter, light brown sugar, whole egg, egg yolk, and vanilla extract.
4. Add the flour mixture and crushed up Oreos and stir until just combined.
5. Press the matcha blondie batter into the pan, top with extra Oreos, and bake for 25-30 minutes. A toothpick inserted into the center should come out clean or with a couple moist crumbs on it.
6. Let it cool completely before cutting into squares and serving.

How to make this recipe gluten-free

To make this matcha blondie recipe gluten-free, swap out the all-purpose flour for a gluten-free all-purpose flour blend and almond flour. Make sure your gluten-free flour blend contains xanthan gum.

Some of my favorite gluten-free blends are Bob's Red Mill Gluten Free 1-to-1 Baking Flour, King Arthur Gluten-Free Measure For Measure Flour, and Cup4Cup Wholesome Flour.

If you're making gluten-free blondies, make sure to let your batter rest for 20 to 30 minutes before baking it in the oven! This will allow the flour to hydrate properly.

Make sure to also use gluten-free Oreos!

How to make this recipe dairy-free

To make dairy-free blondies, simply replace the butter for vegan butter!

If you can't find vegan butter that's unsalted, just add a ¼ teaspoon of salt into the batter instead of ½ teaspoon.

Tips to make the perfect matcha blondies

• Use the best matcha powder you can get. Because matcha is the main flavor of these blondies, it's best to use one that's high quality!
• Rest your batter if you're making these gluten-free. Resting the batter allows the gluten-free flours to properly hydrate, and you can avoid a gritty or sandy texture in your blondies.
• Don't overbake your blondies. Overbaking causes the blondies to become dry, which we want to avoid at all cost! Check for doneness by inserting a tooth pick into the center of the blondies at the 25 minute mark, and if it's not done, put it back into the oven for another 2 or 3 minutes.
• Cool them completely. It's the hardest part about baking, but it's important to wait for them to cool completely to get clean slices.

Frequently Asked Questions

What matcha powder is best?

Ceremonial grade matcha is the best, for both drinks and desserts. It has the best flavor, aroma, and color. That said, it's also the most expensive grade of matcha.

My advice is to use the best matcha that you can afford. If that's culinary grade matcha, that's fine!

Although it may not be as green or aromatic, you can still make these blondies with culinary grade matcha.

Which Oreo cookies should I use?

Since switching to a gluten-free diet, I make these blondies with gluten-free Oreos. You can use regular Oreos, or even golden Oreos.

Stay away from any of the flavored Oreos (e.g., peanut butter, carrot cake, birthday cake, mint, etc.). Those will affect the flavor of the matcha blondies.

Can I make this recipe egg-free?

I haven't tried substituting the eggs with an egg replacer, so I can't say whether an egg substitution would work or not.

How do I get perfect slices?

Cool the blondies completely, and use a very sharp knife! It also helps to wipe the knife after each cut with a damp paper towel or kitchen towel.

How long do these matcha blondies last?

They will last for 4 days in an airtight container at room temperature.

If you plan to store them for longer than 4 days, opt for storing them in your freezer. Wrap each square with cling wrap and store in a freezer bag.

Let the blondies come to room temperature on the counter before serving.
