Instructions

• Preheat your oven to 175°C (350°F) and prepare your cake pans by greasing them and lining the bottoms with parchment paper
• Start by heat-treating the flour for the cookie dough by baking it for 5 minutes at 175°C or microwaving it until it reaches a safe temperature, then let it cool completely
• In a mixing bowl, cream together butter, granulated sugar, and brown sugar until light and fluffy, about 2 to 3 minutes
• Add milk and vanilla extract, mixing until smooth and well combined
• Gradually add the heat-treated flour and salt, mixing until a soft dough forms
• Fold in mini chocolate chips evenly, then divide the dough into small chunks and refrigerate for at least 30 minutes
• In a separate large bowl, beat butter and sugar for the cake layers until pale and fluffy, ensuring proper aeration
• Add eggs one at a time, mixing thoroughly after each addition
• Mix in vanilla extract for flavor depth
• In another bowl, whisk together flour, baking powder, and salt
• Add dry ingredients to the wet mixture in batches, alternating with milk, mixing gently each time
• Fold in sour cream to enhance moisture and softness
• Add mini chocolate chips and mix lightly to distribute evenly
• Divide the batter evenly into prepared pans
• Press small chilled cookie dough pieces into the batter, ensuring they are slightly covered
• Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean
