Rice Cake Marshmallow Recipe: Chewy Sweetness With Gooey Centers

This rice cake marshmallow recipe delivers a perfect balance of chewy and gooey textures in every bite. The combination of soft, pillowy marshmallows nestled within tender rice cakes creates an irresistible treat.

I developed this method after testing multiple ratios to achieve ideal consistency. The key is precise timing and temperature control to ensure the rice cakes maintain their structure while the marshmallows melt into that signature sticky center.

What sets this version apart is its simplicity. With just a handful of ingredients and straightforward techniques, you’ll achieve professional-quality results that rival any bakery’s offerings.

The finished treats feature a delicate exterior giving way to a rich, molten marshmallow center. These are perfect for satisfying sweet cravings or sharing as a homemade gift.

Ingredients for Rice Cake Marshmallow

A handful of pantry staples and a few specialty items create these irresistible chewy, gooey treats.

The rice cakes are critical—look for plain, unsalted varieties at Asian markets or well-stocked grocery stores. Brands like Lundberg or Quaker work well. Marshmallows should be fresh; old ones lose their pillowy texture. For the butter, Plugrá or Land O’Lakes are reliable choices. Vegetable shortening like Crisco ensures easy release from molds without altering flavor.

No light corn syrup? Honey or agave at a 1:1 ratio works, though the texture may vary slightly. For a richer flavor, substitute brown sugar for granulated. If avoiding corn products entirely, glucose syrup is the best alternative. Vanilla extract can be swapped with vanilla bean paste for a more pronounced vanilla flavor (use the same amount).

Store finished treats in an airtight container at room temperature for up to 3 days. For longer storage, freeze for up to 1 month—thaw at room temperature before serving. Dust with powdered sugar just before serving to maintain freshness.

Step-by-Step Instructions for Rice Cake Marshmallow Treats

Precision and patience yield the perfect balance of crisp edges and molten centers.

Step 1: Prepare Work Surface and Rice Cakes

Lightly dust your work surface with the 2 tbsp all-purpose flour to prevent sticking. I prefer using a silicone mat for easy release. Arrange the 8 whole white rice cakes on a separate plate—plain, unsalted varieties work best for this preparation.

Grease four muffin tin cavities with the 1 tbsp vegetable shortening, ensuring complete coverage of the bottom and sides. This creates a nonstick barrier that allows the treats to release cleanly after baking. The shortening’s high smoke point makes it ideal for this application.

Step 2: Create the Marshmallow Mixture

In a heavy-bottomed saucepan, melt the 0.5 cup unsalted butter over medium-low heat. Once melted, add the 0.5 cup granulated sugar and 0.25 cup light corn syrup, stirring constantly until the sugar fully dissolves and the mixture begins to bubble gently.

Remove from heat and immediately stir in the 2 cups miniature marshmallows. The residual heat will melt them completely within 1-2 minutes of constant stirring. Add the 1 tsp vanilla extract and 1 pinch pinch of salt, combining thoroughly to create a smooth, glossy mixture.

Step 3: Assemble the Treats

Working quickly while the mixture is still warm, place one white rice cake in each prepared muffin cavity. Spoon the marshmallow mixture evenly over each rice cake, filling the cavities about ¾ full. The mixture should mound slightly above the rice cake’s surface.

Press a second white rice cake on top of each, creating a sandwich. Use the back of a spoon to gently press down, ensuring the marshmallow mixture spreads to the edges. This layering technique guarantees even distribution of the gooey filling in every bite.

Step 4: Chill and Finish

Refrigerate the assembled treats for at least 2 hours or until completely set. The marshmallow mixture will firm up significantly, transforming from liquid to a chewy, sliceable consistency. This resting period is crucial for achieving the proper texture.

Once chilled, carefully remove the treats from the muffin tin. Dust the tops lightly with the 0.25 cup powdered sugar for a professional finish. The sugar not only adds visual appeal but also provides a delicate contrast to the rich, buttery marshmallow centers.

Storing and Reheating rice cake marshmallow

Room Temperature Storage

Let your treats cool completely before storing. I place mine in a single layer in an airtight container with parchment paper between layers. They’ll keep at room temperature for up to 3 days. The rice cakes stay chewy while the marshmallow centers maintain their gooey texture. 💪

Refrigerator Storage

For longer freshness, store in the refrigerator for up to 1 week. Use the same airtight container method, but add an extra sheet of parchment on top to absorb any moisture. Bring to room temperature for 30 minutes before serving to restore the ideal consistency.

Freezing for Later

These freeze beautifully for up to 1 month. Wrap each treat individually in plastic wrap, then place in a freezer bag. Thaw overnight in the fridge or at room temperature for 2 hours. Dust with fresh powdered sugar after thawing to revive the finish. ❄️

Reheating Tips

For a warm, fresh-baked feel, microwave individual treats for 10-15 seconds. The marshmallow will soften slightly without losing its structure. Avoid over-heating, or the rice cakes may become too soft. Let sit for 1 minute after microwaving for the best texture.

Avoiding Stickiness

If your treats stick together in storage, next time dust them more generously with powdered sugar before layering. I also recommend using wax paper instead of parchment for better separation. Store in a cool, dry place away from direct sunlight.
