1teaspoonbaking soda plus 2 teaspoons hot water(I use teaspoons, not tablespoons)
2cupsall purpose flour(280 grams)
1cupcake or pastry flour(120 grams)
1teaspoonbaking powder
1teaspooncinnamonI'd go with ½ teaspoon or even less
1 ½teaspoonssalt (Morton kosher)
2cupschips (1 cup each Ghirardelli white and milk chocolate
Optional: 1 cup pecans
Instructions
Melt butter lightly in the microwave using one of the lower power settings or do it on high and stir every 20 seconds. Pour into a mixing bowl or the bowl of stand mixer. Let cool for 15 to 20 minutes.
Add brown and white sugar to the melted butter and beat with an electric mixer for 4 minutes. This is a long time, so it helps to have a stand mixer. Scrape down the sides of the bowl and add egg, then yolk., Add vanilla and mix for 30 seconds.
Dissolve the baking soda in hot water and add to the mixture.
Whisk together both of the flours, the baking powder, cinnamon and salt.
Add flour mixture gradually, scraping down sides of the bowl. Add all chocolate chips and nuts (if using) and stir until blended.
If you can, chill for at least 3 hours. Note: I scooped the dough balls onto a plastic wrap-lined plate, covered and chilled the preformed dough balls. I also baked some cookies immediately.
Before baking, let the dough come to room temperature.
Preheat oven to 350 degrees F.
Drop dough (or just arrange the dough balls) on un ungreased baking pan spacing at least 2 inches apart.
Bake small cookies for 10 minutes. Bake larger cookies for 13 to 15 minutes or however long it takes for the cookies to appear set.
