Cream butter and sugar until fluffy and almost white. Add in eggs one at a time until just incorporated. Add in vanilla extract. Slowly add in flour mixture and mix until no dry bits remain.
2 1/2 sticks butter, 2 cups sugar, 2 eggs
Form a log with the dough and place onto wax paper. Wrap tightly. Chill dough for 3 hours or overnight. The log should be about 2 and a half inches in diameter for large cookies. This will make about 20-22. Adjust to make 2 smaller logs if you want smaller cookies.
Pre-heat oven to 350 degrees F. Slice the cookies into 3/8 inch thick rounds and place on un-greased cookie sheet. Bake for 10 – 12 minutes rotating halfway through. Allow cookies to cool for at least 5 minutes on the pan. Using a thin spatula, gently remove the cookies and place on a wire rack to cool.
Once cookies are cool, they can be stacked and stored in an air tight container. Cookies will stay fresh for a week stored this way. They may also be frozen, for 3 months. Cookies can be served plain, or frosted with a prepared chocolate frosting, or our homemade chocolate buttercream. Add sprinkles if you would like.
Notes
When handling the chocolate cookie dough, use cocoa powder, rather than flour on your hands. This keeps them dark and also adds flavor!
