Preparation

• Preheat your oven to 180°C (360°F) and line a baking sheet with parchment paper. While the oven heats, measure out all your ingredients.
• In a medium bowl, combine the softened butter, brown sugar, and sweetened condensed milk. Beat with a hand mixer or whisk for about 2-3 minutes until light and fluffy. Add the vanilla extract and mix.
• In a separate small bowl, whisk together the flour, baking powder, salt, cinnamon, and rolled oats. Fold the dry mixture into the creamed butter mixture until just combined.
• Fold the chocolate chips into the dough and roll into balls about the size of walnuts. Place them on the prepared baking sheet, spacing them about 2 inches apart. Press each ball with the back of a fork.
• Bake for 15 minutes, or until the edges are lightly golden brown. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
