Popcorn Cake is basically just like Rice Krispie treats but made with popcorn instead!

Popcorn Cake

This is such a fun dessert to make for a small gathering, and if you happen to be making it for kids… they really seem to love it. Think about having it out at a casual party. You can slice it up ahead of time so the slices are displayed and ready to grab and eat. This is a dessert you can pick up and eat with your hands, so that works out great!

How to make Popcorn Cake:

You’ll need about 12 cups of popped popcorn. You can either pop some popcorn on your own (using about ½ cup of kernels or utilizing the microwave popcorn), or you can purchase popped popcorn in a bag. It’s important that you remove any stray, unpopped kernels and discard them.

Marshmallows are combined with butter and vanilla in a saucepan over medium-low heat until the marshmallows have melted and you’ve created a marshmallow syrup. At this point, you’ll combine the popped popcorn and the melted marshmallow misture in a large bowl and use a strong wooden spoon to mix those together. You’ll keep mixing until the popcorn is completely coated with the marshmallow syrup.

Then you’ll stir in M&M’s chocolate coated candies and peanuts. The mixture is then scooped into a buttered bundt or tube pan. You’ll use greased hands or waxed paper to press the mixture into the pan. Then you can let it cool for a few minutes before cutting.

Here are some pan options you can order on Amazon to make this cake:

You can either use a tube pan (my preference) or a bundt pan for making this Popcorn Cake.

  • The photos in this post show the popcorn cake made with a TUBE PAN. It has tall, straight sides. It’s cheap on Amazon if you want to pick one up. You can use it to make angel food cake or pound cake as well.
  • And you can also use a regular, classic bundt pan. It will take on a slightly different, rounded shape but still the same general idea.

Serving Popcorn Cake

What other mix-ins are an option?

If you really love peanuts, you can use peanut M&M’s instead of regular. Also, if your Popcorn cake is for a special holiday, consider using the holiday colored M&M’s for a festive look! Or try using the mini Reeses Peanut Butter Cups or cut the regular sized ones into pieces. Chocolate chips are also an option. If you are serving this dessert to people who cannot have peanuts, just leave them out. Be creative with your mix-ins!

    How outrageously extravagant. I want to make this, but with caramel instead of marshmallow. It will be like Crunch n’ Munch Cake!
