Instructions

  1. Step 1: Preheat oven to 350°F (175°C). In a large bowl, cream together 1 cup softened unsalted butter, 3/4 cup granulated sugar, and 3/4 cup packed brown sugar with an electric mixer until light and fluffy, about 3 minutes.
  2. Step 2: Beat in 1 large egg and 1 tsp vanilla extract until smooth.
  3. Step 3: Whisk together 2 1/4 cups all-purpose flour, 1 tsp baking soda, and 1/2 tsp salt in a separate bowl, then slowly add to the wet mixture, blending until just combined.
  4. Step 4: Fold in 1 1/2 cups semisweet chocolate chips evenly.
  5. Step 5: Line a heart-shaped pan with foil or parchment paper and spread dough evenly.
  6. Step 6: Bake for 25-28 minutes until edges are golden and center is set but soft. Cool completely on wire rack.
  7. Step 7: For the frosting, beat 1/2 cup softened unsalted butter until creamy, then add 2 cups powdered sugar, 2 tbsp whole milk, 1/2 tsp vanilla extract, and a few drops of red food coloring. Beat until fluffy and smooth.
  8. Step 8: Spread pink buttercream over cooled cookie cake and decorate with 1/3 cup Valentine's M&Ms by pressing them gently into the frosting.
  9. Step 9: Slice and enjoy your festive Valentine's Day treat.

Frequently asked questions

How long does Soft Heart-Shaped Chocolate Chip Cookie Cake with Pink Buttercream and M&Ms take to make?

How do I store leftover Soft Heart-Shaped Chocolate Chip Cookie Cake with Pink Buttercream and M&Ms?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep (150g) granulated sugar from drying out.

Can I substitute ingredients in Soft Heart-Shaped Chocolate Chip Cookie Cake with Pink Buttercream and M&Ms?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Soft Heart-Shaped Chocolate Chip Cookie Cake with Pink Buttercream and M&Ms for a different number of people?

The recipe is written for 8 servings. Multiply each ingredient by (your serving target / 8). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
