1. Making 100 little chunks of dough is the sort of thing a robot should do.
2. A giant cookie is a great way to intimidate the competition at a cutthroat bake sale.
3. You're from Texas.
4. The extended baking time is just long enough to call your friends to come over for a 'cookies and cocktails' night.
5. It's been a long day. Why pretend, I was going to eat the whole batch anyway.
This will work with almost any cookie recipe*, so grab your favorite** and get in the kitchen.
*This may not be true if you're into replacing traditional ingredients with things that are less traditional like fake sugar.
**Don't have a favorite cookie recipe? I included my favorite quick sugar cookies!
Step 1: Make Your Cookie Dough
I'm assuming you're using a fairly ordinary oven with a fairly ordinary baking sheet that you could otherwise be using to bake a fairly ordinary frozen pizza. And that's the size you'll probably end up with - frozen pizza. Larger if you have a big oven and pans to match.
Your total of sugar and flour needs to be no more than 4 cups to make one large cookie. Count oatmeal as flour if you're making an oatmeal cookie. If your recipe is larger than this and you'd rather not decrease it just split it into two cookies. Come on, it's still better than making dozens.
You might be watching your health and consider skipping the salt in your recipe. Don't. The salt reacts with the flour to improve the texture of the finished cookie.
Also, feel free to use this pre-tested sugar cookie recipe:
Simple Sugar Cookies
1 cup butter/margarine
1 cup sugar
1 tbsp vanilla
2 1/4 cups flour
1 tsp baking soda
1 pinch salt
Mix together the ingredients in the order shown. Bake at 375 degrees for 10-12 for normal cookies, or around 30 minutes for a giant cookie.
If you're leaving the cookie plain give it a good sprinkle of sugar before baking. It's also well suited to mix-ins like chocolate chips, m&ms or nuts, or it's delicious frosted.
