In a small bowl, use the back of a spoon to cream the butter and brown sugar together until light colored and smooth.
Stir in molasses.
Add milk and vanilla extract and stir well. Batter should be nice and smooth at this point.
Add flour, cinnamon, ginger, cloves, and sea salt and stir to mix well.
Serve immediately in two small bowls or refrigerate for 3-4 days. Allow cookie dough to come up to room temperature before enjoying from the fridge.
Notes
This recipe is egg-free and is safe to eat raw as long as the flour has been properly heat-treated.
To heat-treat flour, place the flour in a microwave-safe bowl and heat it on high in 30-second intervals, stirring between each interval, until the flour reaches 165°F. This usually takes about 1 to 2 minutes. OR: Spread the flour on a baking sheet and bake at 350°F (175°C) for 5-7 minutes. The internal temperature should reach at least 165°F to kill any potential bacteria. Let the flour cool completely before adding it to the cookie dough.
