How to Make Heart Shaped Cookie Cake

Preheat your oven to 350°F (175°C). Prepare a heart-shaped cake pan by spraying it generously with non-stick cooking spray to ensure easy release later.
Cream the softened unsalted butter with both light brown sugar and granulated sugar in a stand mixer. Beat until the mixture is fluffy and pale in color, which should take about 2-3 minutes.
Add in the egg and vanilla extract, mixing until everything is well combined. The mixture should be smooth and creamy, inviting a sweet aroma into your kitchen.
Whisk together in a separate bowl, the all-purpose flour, cornstarch, baking soda, and kosher salt. This dry mixture is essential for building the structure of your cookie cake.
Incorporate the dry mixture gradually into the wet ingredients. Mix on low speed until a soft dough starts to form, being careful not to overwork it—this keeps your cookie cake tender!
Fold in the semi-sweet chocolate chips, chunks, and red and white M&M’s using a wooden spoon. Make sure the candies are evenly distributed throughout the dough for that delightful crunch in every bite.
Press the dough firmly into the prepared heart-shaped pan, ensuring an even layer. Top it off with a sprinkle of pink and white heart sprinkles for added decoration before baking.
Bake in the oven for 20-25 minutes. The edges should be lightly golden, while the center remains soft. Keep an eye on it, as over-baking will lead to a firmer texture.
Cool the cookie cake completely in the pan on a wire rack. This step is crucial to prevent the frosting from melting when you apply it.
Beat together the powdered sugar, heavy whipping cream, and pink gel food coloring until you achieve a smooth and creamy frosting. Adjust the color as desired for that perfect Valentine’s Day hue!
Frost the cooled cookie cake by piping the frosting around the edge. Add extra sprinkles on top and feel free to write a sweet message for that extra personal touch!

Optional: Garnish with fresh berries for an added pop of color.

How should I store leftover Heart Shaped Cookie Cake?
For the best taste and texture, store your cookie cake in an airtight container at room temperature for up to 3 days. If you decide to keep it longer, refrigerating it can extend its freshness to about a week. Just remember to let it warm up to room temperature before enjoying a slice again!

Why did my cookie cake turn out dry?
The most common reason for a dry Heart Shaped Cookie Cake is over-baking. Always keep an eye on it during the baking process, especially towards the end of the suggested baking time.
