Did you know that you can make Lava Cupcakes with cake mix? I love making Red Velvet Lava Cupcakes for Valentine’s Day but you can make these all year long with ANY flavor cake mix!

They’re basically a cupcake filled with a rich chocolate ganache – they’re SO rich and easy to make!

Pin it now to save for later

Things that I find magical:

Unicorns (they DO exist)

Love and being with my family.

Snagging the first parking spot in the Walmart Parking lot. (If that’s not magical, I don’t know what is.)

CAKE MIX. (RIGHT?? Isn’t it the BEST?)

Even better: making molten lava cake out of cake mix!

When I was a kid, I seriously thought that chefs did something magical to make the chocolate “lava” flow out of the center of a cake. Why didn’t it bake? How is it melty like that? It must be magic!

As an adult, I have come to understand the workings of the molten lava cake magic trick: ganache. But it’s still magical. Especially in red velvet cupcakes!

What is a Lava Cake?

A traditional Molten Lava Cake (aka Molten Chocolate Cake) is a cross between a soufflé and a flourless chocolate cake. When you dig your spoon into the center of the cake, the chocolate center flows out like lava, get it?

Now, these aren’t traditional lava cakes – they’re lava cupcakes – and they’re made with ganache. But they’re easy to make and SO GOOD, so they’re a good starting point if you’ve never made lava cake before.

Make Lava Cake with CAKE MIX!

I started with a red velvet cake mix. You could use my red velvet cupcake recipe, but I hate making red velvet from scratch. One reason: food coloring.

Am I the only one who manages to get red food coloring over all-the-things when working with it? Droplets that you find for weeks? I barely have to look at my food coloring basket and all of a sudden I have red fingers and blue drops all over my counters.

So, to save my sanity, I made a red velvet cake mix and lined a cupcake tin with liners. Fill up the liners only about halfway – not the usual 2/3 full, otherwise they will spill over.

Then it’s time for the secret ingredient: chocolate ganache!

Lava cupcakes step by step

Make chocolate ganache for the center of the cupcake

You make a simple truffle mixture for the center of these cupcakes.

  • Equal parts chocolate and cream, melted, stirred until smooth
  • Then chill until it sets.
  • Each cupcake gets a tablespoon-sized ganache ball in the center. When you bake the cupcakes, they grow up and over the ganache, but it doesn’t dissolve into the cupcake. It says chocolatey and gooey and good.

Once the cupcakes are baked, you let them cool only slightly, then remove the wrappers and get them ready to serve. When you cut open the cupcake (when it’s still warm) you get a gooey chocolate center.

It’s not super lava, but my lava cupcakes are just as good as a molten lava cake!

Serving Lava Cupcakes

Serve these warm, without the wrappers. If they’ve cooled, just heat them in the microwave for a few seconds. Dust them with powdered sugar for a delicious special dessert!

Make Lava Cake as Lava Cupcakes with your favorite cake mix! Red Velvet Lava Cupcakes are the perfect easy dessert – cupcakes filled with ganache!
Prep Time 20 minutes
Cook Time 20 minutes
Total Time 40 minutes
Yield 24 cupcakes
Serving Size 1 cupcake


  • 1 approximately 15 ounce box red velvet cake mix plus ingredients called for to make the cake (eggs, water, and oil)
  • 8 ounces semi-sweet baking chocolate
  • 1/2 cup heavy cream
  • Powdered sugar for garnish


  • Chop or break up baking chocolate and place in a medium sized bowl. Heat the cream over low heat until it just simmers (or in the microwave for about 45 seconds). Pour over the chocolate. Stir until melted and smooth. (If it’s having a hard time melting, place it in the microwave for about 15 seconds.) Chill chocolate mixture until hardened, at least 2 hours.
  • Preheat oven to 350 °F. Line muffin tins with cupcake liners.
  • Mix up cake batter according to the box directions. Fill each liner about 1/2 full of batter. (You don’t want to fill them as full as 2/3, or they will spill over. A little less than is called for on the box is good.)
  • Remove chocolate ganache from the refrigerator. Scoop 1 tablespoon balls (I used a cookie scoop) and place one ball in the center of each cupcake batter.
  • Bake 20-23 minutes, until a toothpick inserted in the side of the cupcake (not the center!) comes out clean. Cool for just a few minutes in the pans.
  • When ready to serve, remove the cupcakes from the pan and remove the liners. Turn upside down on a plate and sprinkle with powdered sugar.
  • These are best served warm. If they cool off, just heat them for a few seconds in the microwave to heat.

  1. You’re right, there’s something magical about cake that oozes chocolate. These look amazing! Pinned.

  2. These look divine!!! I shared the link on my blog bc I’ll be making them for my Valentine!! Since I’m making ganache, I’m going to crisp up some maple bacon and cover the bacon in the leftover chocolate to garnish. YUM!!

  3. Hi! These look delicious, thanks for sharing! I am going to try these with pink velvet this weekend. Question though ~ when they are not warm, what consistency is the ganache? Is it too hard to bite into… or will it still be fine?

    I will post back when I bake these up & let y’all know what I find out.

    Thank you!

    1. I just made these tonight ~ as per the recipe & mine are a globby chocolate goop 🙁
      I have weird tops where the ganache oozes out over the cake… and when I open the cupcake liner, all the ganache is seeping out the bottom of the cupcake.

      Any ideas for how to remedy?! I am so excited to put these on my Valentine’s menu but they have to look presentable 😉 THANK YOU!

  4. Seeing this makes me so sad that I haven’t been following your blog for ages. You must have a million brilliant recipes I have yet to discover.
