Ingredients:

  • 250g salted butter, softened
  • 200g sweetened condensed milk
  • 350g all-purpose flour, sifted
  • 1 tsp baking powder
  • 50g powdered sugar
  • 100g dark chocolate chips

Instructions:

  1. Cream the Base: Place your 250g of softened salted butter and 50g of powdered sugar in a large bowl. Using a hand mixer or a stand mixer with the paddle attachment, beat them together on medium high for about 4 minutes until the mixture is pale and looks like whipped cream.
  2. Adding the Milk: Pour in the 200g of sweetened condensed milk slowly while the mixer is on low. Continue to beat until the liquid is fully incorporated and the batter is silky.
  3. Incorporate Dry Ingredients: Stop the mixer and add the 350g of sifted all purpose flour and 1 tsp of baking powder. Use a sturdy spatula to fold the flour in by hand. Mix only until no white streaks remain to avoid overworking the gluten.
  4. The Chocolate Fold: Gently stir in the 100g of dark chocolate chips. Ensure they are evenly distributed so every bite has a hit of cacao. The dough should be soft but hold its shape when pressed.
  5. Porting the Dough: Scoop tablespoon sized portions (about 30g each) and roll them into smooth balls between your palms. Place them on a parchment lined baking sheet, leaving about 2 inches of space between each.
  6. Shaping and Texturizing: Use a fork dipped in a little extra flour to gently press down on each ball, creating a cross hatch pattern. Press until the cookie is about half an inch thick, which helps the edges crisp up while the center stays tender.
  7. Precision Baking: Slide the tray into a preheated oven at 350°F (175°C). Bake for exactly 12 minutes until the bottoms are lightly tanned and the edges feel set to the touch. They will look slightly underdone on top, but that’s exactly what you want.
  8. The Cooling Phase: Let the cookies rest on the hot tray for 5 minutes. This allows the internal structure to firm up. Then, transfer them to a wire rack to cool completely. Listen for the faint crackling sound as the edges harden into that signature shatter crisp texture.
