Mix together white sugar and cinnamon in a small bowl until well combined and set aside (you will use this to roll your dough in before baking)

Prepare the Strawberries:

Finely chop the fresh strawberries. Place them on a paper towel to absorb excess moisture, ensuring they are not too wet when added to the dough.

In a large bowl, whisk together flour, cream of tartar, baking soda, and salt. Set aside.

Mix Butter, Oil, and Sugar:

In a separate bowl, whisk the melted butter, vegetable oil, and sugar together until well combined.

Add the eggs and stir well until fully incorporated.

Gradually stir in the flour mixture until a dough starts to form. Be careful not to overmix.

Gently fold in the chopped strawberries and chocolate chips until evenly distributed throughout the dough.

Form the the cookie dough into 2-3 inch balls. Roll each ball in the cinnamon-sugar coating.

Place the dough balls about 2 inches apart onto the prepared baking sheet (either greased or lined with parchment paper).

Bake in the preheated oven at 350°F for about 10-11 minutes. Remove from the oven when they look slightly undercooked in the middle, as they will continue cooking on the baking sheet.

Allow cookies to cool for about 10 minutes before transferring to a wire rack to cool completely.
