I'm fairly new to baking, but I've been attempting to make cookies lately. They taste good, but come out looking like this:
The bottom looks like this:
They spread out a lot in the oven (they went in as balls ~1 inch diameter and came out as flat disks ~4 or more inches across) and don't really have a crust on the bottom. I used these ingredients:
1 stick butter 1/2 cup sugar 1/2 cup brown sugar 1 egg 1 tsp vanilla extract 1/2 cup pumpkin puree 1 1/2 cups flour 1 tsp baking soda 1/4 tsp salt 2 tsp pumpkin pie spice ~1/2 - 1 cup milk chocolate chips
To cream the butter with the white sugar I let it sit for about half an hour, cut it into small chunks, let it sit a little longer, and then alternated beating them with a fork and a hand mixer with beater attachments. I'm looking into getting a stand mixer. The dough for the pictured batch was chilled in the fridge overnight.
How can I keep them from spreading out so much and develop a crust on the bottom?
Edit: I baked them at 350F, fully preheated, for around 15 minutes on a bare cookie sheet. I peeked after about 8 minutes and then probably two more times after that before I took them out.
