Matcha mint Oreos! I’m pretty excited about these cookies, because homemade Oreos have been on my baking bucket list for awhile now. I’ve tried a few different recipes in the past, but none of them really did it for me. But the base recipe for these Oreos comes from Stella Park’s fantastic book, BraveTart: Iconic American Desserts, and they are the real deal. Bake a batch of these and your house will smell like an Oreo factory.
For a festive twist, I decided to go with a matcha mint filling, inspired by the perennially popular Candy Cane Joe Joe’s from my favorite grocery store not in Canada (sad face). I added matcha mostly for color, but its earthy flavor also tempers the sweetness from the candy canes.
A few notes:
- When making the wafers, I find it easiest to roll the dough to the desired thinness right after mixing. Divide the dough in half and roll each half between two sheets of parchment paper. Stick the rolled out dough in the fridge for about half an hour just to firm it up, then cut your rounds. This way, you don’t have to use any extra cocoa powder for rolling and you can use the parchment to line your sheet pans.
- Make and completely cool your wafers before making the filling, as the filling sets quickly and must be used right after mixing. (The wafers keep really well, so you can definitely make this recipe over a couple of days.)
- Crush your peppermint candies really finely. Otherwise your piping tip will get clogged when you fill the cookies and it’ll be hard to get your cookies to lie flat. Also, someone could break a tooth.
- Matcha powders vary quite a bit in potency. I liked how my filling tasted with 1 Tbsp, but if you’re unsure start with less and add more to taste. You can also omit the peppermint extract if you want a more prominent matcha flavor.
Matcha Mint Oreos
Adapted from BraveTart: Iconic American Desserts | Makes about 20 2-inch sandwich cookies
For the Oreo wafers:
- One batch of this recipe, cut into 2-inch rounds and completely cooled
For the matcha mint filling:
- 170g unsalted butter
- 1/4 tsp pure peppermint extract
- 1/8 tsp kosher salt
- 240g powdered sugar
- 1 Tbsp matcha powder
- 1/3 c finely crushed candy canes or peppermint candies
For the matcha mint filling:
- Before making the filling, flip half the chocolate wafers upside down so they can be filled immediately after preparing the filling.
- Sift the matcha powder and icing sugar together and set aside.
- In a small saucepan, completely melt butter over medium-low heat. Simmer, stirring with a heat-resistant spatula, while butter hisses and pops; if you notice brown bits forming along the edges, reduce heat to low. Continue cooking and stirring until butter falls silent, then strain into the bowl of a stand mixer fitted with a paddle attachment. Allow to cool for 5-10 minutes.
- Add the peppermint extract and salt, followed by powdered sugar and matcha. Mix on low to moisten, then increase to medium and beat until creamy and soft, about 5 minutes. If your filling is runny, stick it in the fridge for a few minutes to stiffen slightly (this should only take a few minutes). Stir in the peppermint candies. Transfer to a heavy-duty pastry bag fitted with a 1/2-inch tip and use immediately.
- Pipe about a tablespoon of filling onto each upturned wafer, then sandwich with the remaining halves. Gently twist the cookies to evenly distribute the filling. Allow cookies to set for about half an hour before serving. Store leftovers (if there are any) in an airtight container. They keep well at room temperature for about a week. (For longer storage, keep in refrigerator or freezer; serve at room temperature.)
