Today I’m sharing the sweetest little heart-shaped chocolate chip cookie cake that is completely perfect to bake and share with anyone you cherish for Valentine’s Day–or any other day you want to spotlight your love! This is super quick and easy to make, and can be decorated as simply or as elaborately as you like. And, of course, it’s delicious and fun to eat, too!

Pro Tip

I use and love this 10-inch Wilton heart shape aluminum cake pan. This silicone version is the same size and as of my writing this, a bit cheaper and eligible for Amazon Prime.

Can I make this without a heart-shaped pan?

Yes! Although having a heart-shaped baking pan certainly makes this quick and easy, you can improvise with foil folded and shaped into a heart shape and arranged on a baking sheet. Watch this YouTube video for specifics. You can do this for nearly any specialty shape, not just hearts!

Ingredient Notes

Here are a few notes and shopping tips about the ingredients you’ll need. Find full amounts in the print-friendly recipe card below.

  • Butter, brown sugar, and white granulated sugar to cream together as the base.
  • Wet ingredients: egg, vanilla extract.
  • Dry ingredients: all-purpose flour, cornstarch, baking soda, and table salt.
  • Mix-ins: dark or semi-sweet chocolate chips, M&Ms (optional but fun).
  • Frosting or sprinkles to decorate as you like.

Why add cornstarch to cookie dough?

My favorite trick lately for making a tender cookie cake? Adding a smidge of cornstarch to the dough! There’s science to this. Cornstarch softens the rigid proteins in flour, which helps to make your cookies lighter and more chewy.

This is the same principle as underpins my stay soft chocolate cookies, only those rely on instant pudding mix to achieve the same effect. Instant pudding mix is made up primarily of sugar, flavorings, and a modified cornstarch. You can achieve the same amazing tenderizing effects just by adding cornstarch directly to your cookie dough.

How To Make a Valentine’s Cookie Cake

This is a straightforward one bowl recipe! Bonus, it’s actually faster than making individual cookies because there’s no need to portion or roll.

  1. Make a quick cookie dough. Cream butter and sugar, add eggs and vanilla, sprinkle over the dry ingredients and mix just until even.
  2. Press into the pan – or follow the foil alternative.
  3. Bake at 350 degrees F for about 15 minutes, just until lightly golden.
  4. Cool completely and decorate to your heart’s content. (I couldn’t resist!)

You’ll know the cookie cake is done when the top is lightly golden and fully set, and the edges are very slightly puffy. If you want to be sure, insert a very sharp knife into the center; it should come out clean, without a streak of dough.

Decorating Ideas

Second to eating it, decorating this cookie cake is the best part! There’s really no wrong or right way to do it, so get creative and use whatever you have on hand. Some ideas:

  • Buttercream frosting. Chocolate, vanilla, or colored with gel food coloring; store-bought or homemade.
  • White, pink, or red sprinkles – or a curated Valentine’s sprinkle mix!
  • Sparkling sugar or sugar pearls.
  • Chocolate jimmies.
  • M&Ms. Mini or regular.
  • Red Hots or other candies you love.
  • A big scoop of ice cream. You can scoop this right in the center of the whole heart for a fun kind of mess, or add a scoop on top of individual servings. Chocolate, caramel sauce, and cherries for an added bonus!

I decorated this cake with frosting leftover from a batch of football cupcakes, the pink M&Ms of course, and pink sprinkles I had leftover from my daughter’s Minnie Mouse birthday cupcakes. Simple and cute!

Serving & Storage

Serve From the Pan: For my family or an everyday occasion, I find it simple enough to just leave this cake right in the pan and slice from there. If you have a nice sharp knife, it’s easy enough to slice straight to the bottom and get clean wedges that can be easily transferred to individual plates.

Serve on a Platter: If you want to put this cake on a large platter or plate for serving, consider lining the pan with parchment paper prior to baking. This makes the cookie cake very easy to remove all in one piece. I would also recommend lifting the cookie cake out of the pan prior to decorating, so none of your pretty frosting gets smudged in the process!

Store: Cover this cookie cake very tightly with plastic wrap and it will stay fresh at room temperature for up to 3 days. It can be stored in the baking pan or lifted out to store or serve in a large, flat plastic container.
