Cream butter and sugar in a large bowl. Once it starts to fluff, add egg and vanilla extract.
Once smooth, add dry ingredients and mix until combined. Fold in one cup of chocolate chips.
Using a muffin tin, add 1-2 tbsp of dough. Spread the dough around the sides and bottom, making a layer that’s not too thin, to form a cookie cup.
Bake in oven for 10-15 minutes, or until the top is browned. Remove from oven and use a tool to press down in the middle making a well. Leave in pan to cool.
Once cool, remove the cookies from the tin. Add tempered chocolate as need to coat inside of cups. Let settle and harden at room temperature, or place in freezer.
