In the bowl of a stand mixer, cream together butter, sugar, and vanilla and almond extracts. Sift together flour, cornstarch, and salt. Add to creamed mixture and mix well. Fold in chocolate chips.
Using a small 2 teaspoon cookie scoop, portion the dough onto a parchment-lined baking sheet. Roll the dough into balls. Chill for 30 minutes.
Preheat 350℉. Then, bake the cookies for 10-12 minutes until just set. Dust with a layer of powdered sugar. Let the cookies cool slightly for 2 minutes.
Gently transfer the cookies to a cooling rack. When mostly cool, dust with powdered sugar again. Store in an airtight container.
