It's kind of hard to figure out, as you didn't tell us how what/how much you used of each ingredient...
Here's my best "no-fail" chocolate chip cookie recipe.
See if it looks good to you:
Big Chocolate Chip Cookies
1 stick unsalted butter, at room temp (no microwaving it!)
1/2 c. packed dark brown sugar
1/2 c. granulated sugar
1 large egg
2 Tbsp milk
1 Tbsp vanilla extract
1 c. all-purpose flour
1/2 c. cake flour (I use "Swan's Down" brand in the red box)
1/2 tsp. baking powder
1/4 tsp. salt
1 c. semisweet chocolate chips
Preheat the oven to 375 degrees f. (make sure it's really preheated well!)
In a mixing bowl, cream first 3 ingreds. Add next 3 and blend.
In another bowl, mix together next 4 ingreds, and then add it to the creamed mixture.
Stir in chocolate chips.
Using a 1/4 c. measuring cup, scoop level measures of dough onto greased cookie sheets, spacing each scoop 2" apart. Bake till cookies are browned and firm to the touch, about 15 minutes.
Transfer cookies with a metal spatula to a wire rack (I place mine over paper towels to catch any crumbs)
