Funfetti heart cakes topped with fluffy pink buttercream, sprinkles, and Valentine’s candy!
These Be Mine Confetti Heart Cakes are such a fun way to surprise your Valentine. They start with a Valentine’s funfetti cake mix, bake up perfectly in heart-shaped pans, and get topped with fluffy pink frosting, sprinkles, and a candy-filled border. They pretty much say “be mine” all on their own.
Why You’ll Love This Recipe
- Mini heart-shaped cakes are perfect for the holiday

Ingredient Notes
- Cake mix: Valentine’s Funfetti adds color and sprinkles without needing extras. Any funfetti works if you don’t have the seasonal one.
- Butter: Fully softened butter makes the frosting smooth and easy to spread.
- Heavy cream: Start with less and add more for a soft, fluffy texture that pipes well.
- Gel food coloring: Gel works best so the frosting stays thick and vibrant.
- Royal icing: This adds that fun bakery-style drizzle without having to make icing from scratch.
- Heart pans: Filling only halfway helps the cakes bake evenly and keeps the heart shape clean.
Quick Prep Notes
How full should I fill the heart pans?
Fill each heart pan about halfway. This keeps the cakes from overflowing and helps them bake evenly while keeping a clean heart shape.
How long do these heart cakes take to bake?
Start with the cupcake baking time listed on your cake mix box. Check for doneness, then add 2 to 3 minutes at a time until the tops are lightly golden and a toothpick comes out clean.
Can I make these ahead of time?
Yes. These cakes can be baked and decorated a day ahead. Keep the lids on the pans or store them covered in the fridge until you’re ready to serve or hand them out.
Be Mine Confetti Cakes
Ingredients
- Heart-shaped cake pans
- Valentine’s Funfetti cake mix plus ingredients listed on the box
- 2 sticks butter, softened
- 3½ cups powdered sugar
- 4 to 6 tablespoons heavy cream
- 1 teaspoon vanilla extract
- Light pink gel food coloring
- Hot pink gel food coloring
- Valentine’s Day sprinkles
- Valentine’s Day M&Ms
- Valentine’s Day royal icing
Instructions
- Preheat the oven according to the cake mix directions. Generously spray the heart-shaped pans with baking spray.
- Prepare the cake batter as directed on the box. Divide the batter evenly between 4 to 6 heart pans, filling each about halfway.
- Bake using the cupcake bake time listed on the box as your starting point. Check for doneness, then add 2 to 3 minutes at a time until the tops are lightly golden and a toothpick inserted in the center comes out clean. Let the cakes cool completely.
- To make the frosting, beat the butter until smooth and creamy. Add half of the powdered sugar and mix well. Add the remaining powdered sugar, heavy cream, and vanilla, then beat until fluffy and smooth.
- Divide the frosting evenly between two bowls. Tint one light pink and the other hot pink.
- Spread the light pink frosting over the top of each cooled cake. Add sprinkles and drizzle with Valentine’s royal icing.
- Transfer the hot pink frosting to a piping bag and pipe a decorative border around the edges. Scatter Valentine’s M&Ms along the border.
- Serve right away, or snap the lids on the pans and save for later.
FAQ
Do I have to use Valentine’s Funfetti cake mix?
No. Any funfetti or white cake mix works. The Valentine’s version just adds seasonal color and sprinkles.
Can I use store-bought frosting instead of homemade?
Yes. Store-bought vanilla frosting works fine. Whipping it with a little heavy cream will give it a fluffier texture if you want a homemade feel without extra effort.
Do these need to be refrigerated?
Because of the buttercream, it’s best to refrigerate them if storing longer than a few hours. Let them sit at room temperature for about 15 minutes before serving.
Can I freeze these cakes?
Yes. Freeze the unfrosted cakes tightly wrapped for up to one month. Thaw completely before frosting and decorating.
Sprinkle of Fun
These are perfect for a low-key Galentine’s night with friends. Make and decorate the cakes ahead of time, then set them out while you watch the Parks and Recreation Galentine’s Day episode together. Keep it simple, cozy, and fun. When it’s time to head home, hand each friend a heart cake to take with them- a very Leslie Knope–approved ending to the night.
