Remember those sweet treats from your younger days? Now you can whip them up at home with these look-alike heart-shaped snack cakes. Soft vanilla cake wraps around a dreamy marshmallow center, all covered in a crisp pink shell that breaks perfectly when you take a bite. Make them yourself and you'll know exactly what's going into each delicious cake.
I couldn't believe my daughter's face when we first made these together. She was shocked we didn't need to buy them! These days, we can't imagine Valentine's Day without our cake-making team - she handles one part while I tackle another.
Key Ingredients Breakdown
- White cake mix (1 box): forms the ideal foundation for these special treats
- Sour cream (1 cup): keeps everything soft and prevents drying out
- Marshmallow creme (7 ounces): delivers that iconic fluffy middle
- Almond bark (32 ounces): gives you that flawless outer layer
- Eggs and butter at room temp: vital for everything to blend right
- Pink gel food coloring: won't mess up your coating texture
Building Your Tasty Snack Cakes
- Step 1: Cake Foundation
- First, warm your oven to 350°F. Put parchment in your pans with extra hanging over the sides for grabbing later. Mix your cake mix and sugar with wet stuff just until combined. Throw in flour and sour cream at the end, mixing till you've got a nice smooth batter. Spread it out evenly - thinner layers will make your cakes taste more like the real deal.
- Step 2: Whipping Up The Middle
- Whip marshmallow creme with butter until it's super light - about 3 minutes should do it. Add powdered sugar bit by bit, waiting between additions. Splash in vanilla and salt, then adjust with cream until it's smooth enough to pipe but still holds its shape.
- Step 3: Putting It All Together
- Start at the edges of your cooled cake and cut heart shapes moving toward the middle to get as many as possible. Put filling in a swirl on half your hearts, leaving a little space around the edge. Set the other hearts on top and press down gently so filling reaches the sides. Stick them in the freezer until they're rock solid.
- Step 4: Making It Pretty
- Melt your almond bark in short bursts, stirring often. Add some shortening for extra shine and smoothness. Keep some white for decoration, and turn the rest pink. Let it cool a bit - if it's too hot, your filling will melt!
- Step 5: Finishing Touches
- Dunk each frozen cake completely, letting extra coating drip away. Put them on parchment to harden. Once they're set, drizzle that white coating you saved in zigzags across the top.

My mom always taught me to check if the coating's ready by dipping a spoon back - it should set in about 30 seconds if it's just right.
Smart Assembly Tricks
Getting temperatures right makes everything easier. Cold cake cuts clean, filling that's not too cold spreads nicely, and frozen cakes are a breeze to dip without falling apart.
Nailing The Outer Layer
Getting that coating just right comes down to heat and timing. If it's too hot, you'll end up with see-through coating, but too cool and it'll be chunky. You want it flowing like warm honey for best results.
Keeping Them Fresh
These treats stay good for up to a week in an airtight container at room temp. That outer coating works like a seal to lock in moisture and freshness in the cake.

I've learned over the years that taking your time and watching temperatures closely gets you the fanciest looking results. Folks never believe these are homemade when I bring them out! There's something really special about bringing back those childhood flavors while making new memories in your own kitchen.
Frequently Asked Questions
- → Can these be prepared ahead of time?
- Sure! Keep them in a sealed container at room temperature for up to 5 days, or refrigerate for 2 weeks.
- → Why freeze the cakes before dipping?
- Freezing makes the cakes sturdy and keeps them from breaking apart when dipped in the warm coating.
- → Is regular chocolate okay instead of almond bark?
- You can, but almond bark sets better and doesn’t melt as easily at room temperature.
- → Why gel-based food coloring?
- Liquid coloring can make the almond bark grainy, but gel works smoothly since it’s oil-based.
- → Can I freeze the completed cakes?
- Absolutely. Store them up to 2 months in a sealed container with wax paper separating the layers.
