Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.
Using a stand mixer or a hand held electric whisk, cream together butter and sugar in a large bowl.
1 cup butter, 1 cup granulated sugar
Add the egg and vanilla extract, and beat to combine.
1 egg, 2 tsp vanilla extract
In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
2¼ cup gluten free all purpose flour, 1 tsp baking powder, 1/2 tsp baking soda, 1/2 tsp sea salt
Add the dry ingredients to the bowl of wet ingredients and beat on low until a dough forms. Divide the dough equally into 2 separate bowls (I like to use a food scale to divide evenly).
In the first bowl, add ground up freeze dried strawberries and food coloring (if using) and knead until pink and uniform.
3/4 cup freeze dried strawberries, OPTIONAL: 3-4 drops red food coloring
In the second bowl, add matcha powder and knead to combine evenly.
1 tbsp matcha powder
Fold in the remaining 1/2 cup of white chocolate chips into each bowl.
1 cup white chocolate chips
Scoop a 1½ tablespoon of each dough (I used slightly rounded tablespoons) and press them together. Roll in the palm of your hands until a ball is formed.
Place on the prepared baking sheet, make sure they are at least 2 inches apart (you may need to bake in 2-3 batches).
Bake for 11-13 minutes until the edges are golden, and the centers are puffed up.
Cool for 10 minutes, then transfer carefully to a wire rack using a spatula to cool completely. They'll be fragile but will set as they cool.
