Instructions

Step 4: Gradually add the dry ingredients to the wet ingredients and mix on low speed until just combined.
Step 5: Fold in 1 1/2 cups semisweet chocolate chips evenly.
Step 6: Lightly grease a 9-inch heart-shaped cake pan and press the cookie dough evenly into the pan.
Step 7: Bake for 25-30 minutes until the edges are golden and the center is set but still soft.
Step 8: Remove and cool completely on a wire rack.
Step 9: Spread 1 cup pink buttercream frosting evenly over the cooled cookie cake.
Step 10: Decorate the top with 1/2 cup M&M candies pressed gently into the frosting for a colorful finish.
