This mini heart cake recipe uses a simple vanilla batter baked in silicone heart molds, then finished with a smooth chocolate coating for a polished look. These mini cakes are soft, tender, and just the right size for gifting, sharing, or serving as individual desserts.

Okay, but why do these feel like something I would've paid way too much for at a bakery? So cute!

Bailey's Thoughts ...
I made these-mini heart shaped cakes as Valentines Day gifts for my boys' teachers and bus drivers, and I honestly can't get over how cute they turned out. Pinterest is full of beautiful desserts that look amazing but feel impossible to pull off at home. This isn't that. These mini heart-shaped cakes are genuinely doable, even if baking isn't your thing, and they feel thoughtful and special. They also taste really great.
The cakes themselves are soft, tender, baked in little heart molds so they come out perfectly shaped every time. Each one gets pressed into a glossy chocolate coating that sets into the prettiest shell. You can stop there or add some simple decoration.
A few things that really help: freeze the cakes completely before adding the chocolate. Don’t rush that step. Fully frozen cakes are what give you a clean release. If you have a scale, use it, since evenly filled molds bake more consistently, but filling the molds halfway works well too. And don’t overthink the decorating. The chocolate finish does most of the work for you.

Ingredients
All-Purpose Flour: This is the base of the cake and gives it structure while keeping the crumb soft.
Baking Powder: Provides lift so the cakes rise evenly and don’t bake up dense.
Baking Soda: Works with the sour cream to help the cakes rise and stay tender.
Salt: Balances the sweetness and sharpens the overall flavor of the cake.
Unsalted Butter: Adds richness and flavor; using unsalted butter gives you full control over the salt level.
Neutral Oil: Keeps the cakes moist, even after chilling and freezing; look for a mild oil with no strong flavor.
Granulated Sugar: Sweetens the cake and helps create a soft, tender texture.
Large Egg: Helps bind the batter and provides structure as the cakes bake.
Egg Yolk: Adds richness and gives the cakes a softer, more tender crumb.
Full-Fat Sour Cream: Adds moisture and tenderness; full-fat works best for consistent texture.
Vanilla Extract: Adds warmth and rounds out the flavor of the cake.
Chocolate Chips: These melt into the coating, so choose a chocolate you enjoy eating on its own.
Coconut Oil: Helps the melted chocolate stay smooth and set cleanly once chilled.
See recipe card for quantities.
Instructions

- Prepare the batter. Mix the dry ingredients in one bowl and the wet ingredients in another, then combine just until smooth. Let the batter rest briefly before filling the molds.

- Fill the molds. Place the silicone heart molds on a sheet pan and fill each cavity evenly, aiming for about halfway full so the cakes bake without overflowing.

- Bake the cakes. Transfer the filled molds to the oven and bake until the cakes are set and lightly golden. Freeze until firm, and then remove each cake.

- Prepare the chocolate coating. Clean and dry the molds, then melt the chocolate with the oil until smooth. Pour the melted chocolate evenly into each mold cavity. Place frozen cakes upside down, pressing gently so the tops make contact. Freeze until chocolate sets.

- Remove the cakes from the molds.
Once the chocolate is fully set, gently peel back the silicone molds to release the cakes. The chocolate should be smooth, firm, and release cleanly, creating a neat, defined heart shape.

- Decorate the cakes.
Decorate the cakes as desired using frosting, sprinkles, or candy accents. See the video above for details on the specific designs shown.
Top Tip
When baking in molds, precision matters. Weighing the batter keeps the cakes from rising over the edges and losing their shape.
Substitutions
Full-fat sour cream: Substitute full-fat Greek yogurt in an equal amount. This substitution has been tested and works well.
Vanilla extract: Substitute vanilla bean paste or imitation vanilla in the same amount.
Chocolate chips: Substitute chopped chocolate or chocolate melting wafers. Choose a chocolate that melts smoothly.
Coconut oil: Substitute butter or vegetable shortening in an equal amount. This helps the chocolate melt and set properly.

Equipment
Silicone Heart Cake Mold: Shapes the cakes evenly and allows for easy release after freezing. This mold is required for the recipe. Amazon and Hobby Lobby have similar options.
Kitchen Scale: Helps portion the batter evenly so the cakes bake consistently and don’t overflow. I always use a scale when baking. This is the one I have had for 2 years. It's inexpensive and works well.
12" Piping Bags: Only needed if you are using buttercream to decorate your mini heart cakes.
#18 Open Star Icing Tip: Used to create the multi colored buttercream "stars" shown in the photos.
Pink Fondant: Used with the heart molds to create the conversation hearts that top the mini cakes in the photos.
Mini Heart Mold Set: Used to create the fondant hearts shown in the photos. Amazon and Hobby Lobby have similar options.
Bakery Boxes: Each box fits 2 mini heart cakes. Perfect for gifting.
Stickers (for gifting): I order my bakery box stickers from The Pink Crumb. The ones shown in the video and photos are sold out, but she has lots of options.
Storage
Refrigerate: Store the finished mini cakes in an airtight container in the refrigerator for up to 4 days. Let them sit at room temperature for a few minutes before serving so the cake softens slightly.
Freeze: These freeze very well. Place the coated cakes in a single layer in a freezer-safe container and freeze for up to 2 months. Thaw in the refrigerator or at room temperature before serving.
FAQ
Yes. The shape and release method depend on silicone molds. A metal pan or standard cake pan will not work the same.
Freezing makes the cakes firm so they release cleanly from the molds and don't crumble.
No. The chocolate coating gives them a finished look on it

Mini Heart Shaped Cakes
Description
This mini heart cake recipe uses a simple vanilla batter baked in silicone heart molds, then finished with a smooth chocolate coating for a polished look. These mini cakes are soft, tender, and just the right size for gifting, sharing, or serving as individual desserts.
Ingredients
Mini Heart Cakes
- all-purpose flour (1 cup | 120 g)
- baking powder (¾ tsp)
- baking soda (¼ tsp)
- fine salt (¼ tsp)
- unsalted butter (¼ cup | 57 g), melted and cooled
- neutral oil (¼ cup | 55 g)
- granulated sugar (¾ cup | 150 g)
- large egg (1 | 50 g)
- egg yolk (1 | 18 g)
- full-fat sour cream (½ cup | 120 g)
- vanilla extract (1 tsp)
Chocolate Topping
- chocolate chips (¾ cup | 130 g)
- coconut oil (1½ tsp)
Instructions
- Preheat the oven to 325°F.
- In a medium bowl, whisk together all-purpose flour (1 cup), baking powder (¾ tsp), baking soda (¼ tsp), and fine salt (¼ tsp) until evenly combined.
- In a separate bowl, whisk unsalted butter (¼ cup), neutral oil (¼ cup), and granulated sugar (¾ cup) until smooth. Add large egg (1) and egg yolk (1) and whisk until fully incorporated, then mix in full-fat sour cream (½ cup) and vanilla extract (1 tsp).
- Gently fold the dry ingredients into the wet ingredients just until combined.
- Place the silicone heart mold on a quarter sheet pan. Fill each cavity with 60–65 grams of batter, or about halfway full.
- Bake 16–20 minutes, or until the cakes are set in the center. Let cool, then transfer the entire mold to the freezer and freeze for at least 3 hours. The cakes should release easily once fully frozen. If they don’t, freeze longer.
- Once the cakes are removed, wash and dry the silicone molds thoroughly.
- Add chocolate chips (¾ cup) and coconut oil (1½ tsp) to a microwave-safe bowl. Microwave in 20–30 second intervals, stirring well between each, until fully melted and smooth.
- Pour the melted chocolate evenly into each clean mold cavity. Working quickly, place the frozen cakes upside down into the chocolate, gently pressing so the tops make contact with the coating. Return the mold to the freezer for 15 minutes, then pop the cakes loose.
Notes
For the most consistent results, weighing the batter is recommended.
