Preheat the oven to 350 degrees Fahrenheit and grease the cookie sheet.
Add 1 cup softened butter, 1.25 cups granulated sugar and .75 cups brown sugar into mixing bowl. Cream together butter and sugar until light and fluffy (usually this takes 2 - 3 minutes).
Add 2 eggs and 1 teaspoon of vanilla extract to the mixing bowl. Mix together on medium speed until combined.
Mixing on low, slowly add in 2.5 cups flour, 1.25 teaspoons baking soda and .25 teaspoons of salt. Continue mixing until well combined.
Fold in 1 cup of chocolate chips.
Take large 2 - 3 tablespoon balls of dough and place them on the cookie sheet. Sprinkle heart sprinkles on top if desired.
Bake at 350 degrees Fahrenheit for 10 - 12 minutes or until edges are light brown and firm.
Remove from the oven and use a heart shaped cookie cutter to cut cookies.
Allow cookies to completely cool before moving them from the baking sheet.
Notes
Tips
Adding sprinkles or other add-ins: you can add the sprinkles either directly into the dough, or you can simply sprinkle them on the tops of the balls of dough right before baking.
Baking dough: if you want, you can simply take all of the dough and spread it in one sheet on the baking sheet instead of making large balls of dough.
Don't overcook - to get the soft, chewy texture make sure not to overcook the cookies. Remove them from the oven when the edges are just light brown and firm. The centers will continue to firm up as they cool.
Allow to cool - after cutting the baked cookies with the cookie cutter, allow them to cool before moving them. This will help prevent them from falling apart.
