Add flour, sugar, matcha powder, and salt to a food processor. Process for a couple of seconds to combine. Now, add butter and process again until fully combined and crumbled. Finally, add egg and mix again until completely smooth dough.
Transfer the dough to a lightly floured work surface. Dust your hands with some more flour and knead the dough until it comes together into a ball. Divide into 2 equal pieces. Using a rolling pin, flatten each piece into approximately 1/8 inch thick disc. Tightly wrap each with plastic wrap and refrigerate for 30 minutes.
Meanwhile, preheat the oven to 350°F. Line a large baking sheet or a baking pan with parchment paper and set aside.
Remove the chilled dough from the refrigerator and knead several times. Working on a lightly floured surface, roll out the dough again and cut into square pieces. Cut each square into 4x2 rectangles. Move the rectangles to the refrigerator and repeat the process with any remaining dough.
Divide the plum jam between half of the rectangles, leaving about ¼ inch of space around the edge. Top each with the remaining rectangles. Seal the edges using the tines of a fork. Finally, with a sharp, paring knife, make a couple of small slits in the top of each tart.
Bake for 25 minutes. When done, remove from the oven and transfer to wire rack to cool. Optionally, prepare the glaze. Add all glaze ingredients to a medium bowl and mix well using a hand mixer. Drizzle chilled tarts with the glaze and cool completely before serving.
These colorful matcha pop tarts require some time to prepare but are definitely worth it! They are extremely delicious and completely gluten-free with a wonderful addition of matcha powder which gives its unique green tea flavor we all love so much.
The recipe itself is really not that complicated although it might take some practice especially for those who are not used to working with dough. This is why it’s really useful to use your food processor to do the job for you.
When you add the butter to the flour mixture, make sure to process until the mixture is completely incorporated and starts to crumble. This will create a sticky mixture that will allow you to work with the dough later.
When working with the dough, you’ll probably have to repeat the process of kneading and rolling out several times (this way, you’ll transform any dough leftovers into these fantastic matcha pop tarts).
Make sure to keep the prepared tarts in the refrigerator while you’re working on the next batch. The dough is based on butter which melts quite easily which can make things more difficult.
Finally, fill these lovely tarts with your favorite jam and optionally add some finely chopped nuts and bake until slightly golden brown (you will have to keep an eye on this because the green matcha tone can easily trick you and you don’t wish to end up burning them).
