Popcorn Cake

A super easy and yummy no-bake treat, Popcorn Cake is a house favorite!

Yesterday was the most beautiful day.  It reached almost 70 degrees, and when it’s normally in the 30’s this time of year, it was a very welcome surprise.  With my windows thrown open, kids playing outside all afternoon, and flip flops on my feet, spring was definitely in the air, and it was the perfect day to make one of our favorite treats…a Popcorn Cake!

Popcorn Cake

What a fun cake this is!  It’s perfect for any party or get together, especially for spring and with Easter coming. The best part?  It’s SO easy, and takes less than 15 minutes to make. I have a daughter that has Celiac disease and needs to eat gluten-free, and this is a cake that’s perfect for her.

A delightful combination of popcorn and melted marshmallow, it’s always a hit whenever I make it. For the extra pop of spring color (and a yummy chocolate crunch) I added Mini Cadbury Eggs, but I often use M&Ms–peanut, plain, or peanut butter. It’s yummy no matter what!

I like to make it with air-popped popcorn, but you can definitely use microwave popcorn if that’s what you have on hand. The color will be a little more yellow, and the taste slightly different if you use a movie theater version. It’s yummy either way!

An easy and yummy cake made with popcorn, marshmallows, and M&Ms!


  • 10.5 oz. bag mini marshmallows
  • 1/4 cup butter
  • 16 cups popped popcorn , (3/4 cup unpopped)
  • 1 large bag M&Ms or Mini Cadbury Eggs


  • Pop your popcorn first!  I always use air-popped popcorn, and I popped 3/4 c. popcorn kernels.  This will make a little more than you need, but then you'll just have a little leftover to munch on! Measure out 16 c. of popped corn into a large bowl that will be big enough mix it all together.  If you don't have a popcorn maker, you can definitely use microwave popcorn instead. It may be a little more yellow and taste a bit different due to the butter, but it will still work.
  • In a large pot, melt the butter over medium heat, then add the marshmallows.  I stir pretty constantly, to make sure the marshmallows don't burn on the bottom. Once it's completely melted, pour on top of your popped corn, and stir until every piece is covered. 
  • Add your M&M's, and gently stir them into the popcorn, making sure they are throughout the whole bowl.Spoon the popcorn mixture into a lightly buttered bundt pan, and press firmly.  (Don't use cooking spray–it will make it taste funny.)  You don't need to let it sit for very long–only about 5 to 10 minutes, then you can turn it upside down onto a cake plate.  You will probably need to take a table knife and gently go around the edges, then use your fingers to loosen it a little.  Once  it's loosened, it will come out pretty easily.
