Classic Chocolate Drop Cookies

This was my first time baking chocolate drop cookies.

I watched Anna Olson's Youtube video recently and decided to have a go.

The first attempt went badly.  The cookies were rather hard because I used butter spread instead of pure butter.

The second attempt went well and the cookies tasted excellent.  This time, I used shortening for cookies and pastry.  I even remembered the recipe by heart this time.

Chocolate Drop Cookie recipe by Anna Olson

Wet ingredients

½ cup unsalted butter, at room temperature (115g)
½ cup packed light brown sugar (90g)
½ cup granulated sugar (90g)
1 large egg, at room temperature
1 tsp vanilla extract (10 ml)

Dry ingredients
1 ¼ cup all-purpose flour (185g)
1 tbsp cornstarch (15ml)
½ tsp baking soda (7.5g)
½ tsp salt (7.5g)

To be added last
1 ½ cup chocolate chips (225g)
1 cup lightly toasted, coarsely chopped pecans (optional) (150g) (I used roasted walnuts)

(Note:I am planning to make another batch of cookies using a reduced amount of sugar because I find 180g of sugar is a bit too much for my teeth)

Below are the photos of the cookies:
