Instructions
1. Prepare the Cake Pan
Lightly grease a Bundt pan or large tube cake pan with butter or nonstick cooking spray.
Make sure to grease the center tube and all the sides thoroughly so the popcorn cake releases easily after setting.
Set aside.
2. Prepare the Popcorn
Measure 14 cups of popped popcorn.
Remove any unpopped kernels and hard pieces, as these can be unpleasant to bite into.
Place the popcorn in a very large mixing bowl.
If necessary, divide it between two bowls to make mixing easier.
3. Melt the Butter
In a large saucepan or Dutch oven, melt the butter over low heat.
Stir gently until completely melted.
Keep the heat low to prevent the butter from browning or burning.
4. Add the Marshmallows
Add the mini marshmallows to the melted butter.
Stir continuously over low heat until the marshmallows are completely melted and the mixture becomes smooth, glossy, and creamy.
Remove the saucepan from the heat.
Stir in the vanilla extract, if using.
Avoid overheating the marshmallows because excessive heat can make the finished popcorn cake hard and difficult to chew.
5. Combine the Marshmallow Mixture and Popcorn
Slowly pour the melted marshmallow mixture over the popcorn.
Using a large greased spatula, gently fold the popcorn until every piece is evenly coated.
Work carefully so you don’t crush the popcorn.
Allow the mixture to cool for a minute or two before adding the M&M’s. This helps prevent the chocolate candies from melting into the warm marshmallow mixture.
6. Add the M&M’s
Add the 2 cups of plain M&M’s to the coated popcorn.
Gently fold until the candies are distributed throughout the mixture.
Reserve a small handful of M&M’s if you want to decorate the top of the cake.
7. Transfer to the Cake Pan
Spoon the popcorn mixture into the prepared Bundt pan.
Lightly grease your hands or a spatula with butter or nonstick cooking spray to prevent sticking.
Gently press the popcorn mixture into the pan, filling the bottom and sides evenly.
Important: Don’t press too firmly. The goal is to help the popcorn cake hold together while keeping its light, airy texture.
8. Let the Cake Set
Allow the popcorn cake to cool and set at room temperature for approximately 30–60 minutes.
The marshmallow mixture will firm up as it cools, helping the cake hold its shape.
Avoid refrigerating it for too long, as cold temperatures can make the marshmallow mixture excessively firm.
9. Remove from the Pan
Once the cake has completely set, gently loosen the edges with a greased spatula if necessary.
Place a large serving plate over the Bundt pan.
Carefully flip the pan upside down and gently lift it away.
If the cake sticks, allow it to sit for a few minutes at room temperature and try again.
10. Decorate and Serve!
Arrange extra M&M’s over the top of the popcorn cake.
Add colorful sprinkles or mini chocolate candies for an extra festive appearance.
Use a sharp or lightly buttered knife to cut the popcorn cake into slices.
Serve immediately and enjoy this sweet, crunchy, and wonderfully chewy party treat!
Expert Tips for the Perfect Popcorn Cake
- Use fresh popcorn: Freshly popped popcorn gives the cake the best flavor and texture.
- Remove unpopped kernels: Always check the popcorn carefully before mixing.
- Choose plain popcorn: Lightly salted popcorn works well, but avoid heavily buttered varieties that can make the mixture greasy.
- Melt marshmallows slowly: Low heat creates a smooth mixture and helps keep the finished cake soft.
- Grease your utensils: Buttered hands and spatulas make sticky marshmallow mixtures much easier to handle.
- Let the mixture cool slightly: Add the M&M’s after the marshmallow mixture stops steaming to reduce the chance of melting their chocolate shells.
- Fold gently: Avoid crushing the popcorn when mixing everything together.
- Don’t compact the mixture: Press just enough to help the cake hold its shape.
- Grease the Bundt pan generously: This makes unmolding much easier.
- Allow enough setting time: The cake needs to cool completely before slicing.
Delicious Variations
Chocolate Popcorn Cake: Add ½ cup mini chocolate chips after the marshmallow mixture has cooled slightly for an extra chocolatey treat.
Peanut Butter Popcorn Cake: Add ¼ cup creamy peanut butter to the melted butter and marshmallow mixture for a delicious peanut butter flavor.
Christmas Popcorn Cake: Replace the plain M&M’s with red and green holiday M&M’s and finish with festive Christmas sprinkles.
Birthday Party Popcorn Cake: Use colorful M&M’s, rainbow sprinkles, and mini candy-coated chocolates for a fun birthday dessert.
Caramel Popcorn Cake: Drizzle caramel sauce over the finished cake for an extra-sweet, buttery variation.
White Chocolate Popcorn Cake: Fold in ½ cup white chocolate chips after the marshmallow mixture has cooled slightly.
Chocolate Peanut Butter Popcorn Cake: Add mini chocolate candies and drizzle melted peanut butter over the finished cake.
Holiday Movie Night Cake: Mix in colorful candy-coated chocolates and mini pretzels for a sweet-and-salty snack-inspired dessert.
What to Serve with Popcorn Cake
This fun dessert pairs wonderfully with:
- Cold milk
- Hot chocolate
- Vanilla ice cream
- Chocolate milkshakes
- Fresh strawberries
- Chocolate-covered pretzels
- Brownie bites
- Sugar cookies
- Fresh fruit platters
- Homemade lemonade
For a fun party dessert table, place the popcorn cake in the center and surround it with colorful candies, cookies, and other bite-sized treats.
Make-Ahead and Storage Instructions
Make Ahead: Prepare the popcorn cake up to 1 day before your party. Let it set completely, remove it from the pan, and store it covered in an airtight container.
Room Temperature: Store in an airtight container in a cool, dry place for up to 2–3 days. Keeping it away from heat and humidity helps preserve its texture.
Refrigerator: Refrigeration is generally not recommended because the marshmallow mixture can become hard and the popcorn may lose its crispness.
Freezing: Freezing is not recommended because thawing can change the popcorn’s texture and make the cake sticky.
Serving: For the softest texture, let the popcorn cake sit at room temperature before slicing if it has been stored in a cool environment.
Frequently Asked Questions
Can I use microwave popcorn?
Absolutely! Plain or lightly salted microwave popcorn works well. Avoid heavily buttered or strongly flavored varieties because they can overpower the sweetness of the marshmallows.
Why is my popcorn cake falling apart?
The marshmallow mixture may not have coated the popcorn evenly, or the cake may need more time to set. Make sure every piece is lightly coated and gently press the mixture into the pan.
Why is my popcorn cake too hard?
Overheating the marshmallows or pressing the popcorn mixture too firmly can result in a hard, dense cake. Melt the marshmallows slowly over low heat and handle the mixture gently.
Can I use large marshmallows instead of mini marshmallows?
Yes! Large marshmallows can be used in the same weight. Cut them into smaller pieces if desired to help them melt more evenly.
Can I use a regular round cake pan instead of a Bundt pan?
Definitely! A greased 9-inch round cake pan or tube pan works well. A Bundt pan simply gives the popcorn cake its classic ring-shaped appearance.
Do I need to bake this popcorn cake?
No! This is a completely no-bake dessert. The melted butter and marshmallows act as the binding mixture that holds the popcorn and M&M’s together.
When should I add the M&M’s?
Add them after folding the marshmallow mixture into the popcorn and allowing it to cool slightly. This helps prevent the candy shells from cracking or the chocolate from melting.
How do I get the popcorn cake out of the Bundt pan?
Grease the pan thoroughly before adding the popcorn mixture. Once the cake is completely set, loosen the edges gently, place a serving plate over the pan, and invert carefully.
