Rice Krispie Treat Recipe with Pudding Mix: No-Bake Chewy Bars With Hidden Creamy Twist

This no-bake Rice Krispie treat recipe with pudding mix delivers a creamy surprise inside every chewy bite—no marshmallow mess, just rich pudding flavor. The secret lies in melting butter properly and folding in pudding mix at the right temperature, creating bars that stay soft yet hold their shape.

I developed this version after years of perfecting the balance between crispy edges and velvety centers, ensuring every cut reveals that hidden pudding twist.

What sets these apart is the foolproof technique: softened butter (not melted) combines with marshmallows and pudding mix to form a thick, spreadable base. The cereal gets coated evenly, then pressed into a pan for clean, perfect cuts.

No special equipment needed—just a microwave-safe bowl and a little patience for the butter to cool slightly before mixing.

By the time you're done, you'll have restaurant-quality bars with a satisfying snap and a creamy pudding surprise in every bite. The texture stays chewy at room temperature but melts slightly when warm, making these perfect for parties or gifting.

Store them in an airtight container for up to a week, though they rarely last that long.

For extra indulgence, press chocolate chips or sprinkles into the top layer before cutting. These treats are beginner-friendly but impressive enough for holidays or potlucks. Let's get started—your taste buds will thank you.

Ingredients for rice krispie treat recipe with pudding mix

Soft butter, gooey marshmallows, and pudding mix create chewy bars with a creamy surprise inside.

The butter is non-negotiable—unsalted, softened to room temperature (about 65°F). I grab mine from Trader Joe's because it's consistently high quality, but any good brand works. For the marshmallows, mini marshmallows are key—they melt evenly and create that perfect chewy texture. The pudding mix? Instant vanilla is a must—it dissolves completely when mixed with milk. Pro tip: measure your marshmallows by volume, not weight, for consistency. If your kitchen gets warm, chill the butter for 10 minutes before mixing to prevent melting too fast.

No pudding mix on hand? Mix 1 cup powdered sugar, 2 tbsp cornstarch, 1/4 tsp salt, and 1 tsp vanilla extract as a substitute. Out of chocolate chips? White chocolate chips or butterscotch chips work too—just adjust the amount to taste. The cereal can be swapped for corn flakes or crispy rice cereal, though Rice Krispies give that classic snap. For extra richness, add 1 tbsp peanut butter to the butter mixture. And if you're feeling fancy, press a layer of crushed Oreos between the top and bottom for a cookie twist.

These stay fresh for 5-7 days in an airtight container at room temperature, though they rarely survive that long. For gifting, wrap individual bars in parchment paper and tie with ribbon. Freeze for up to 3 months if you're prepping ahead—just let them sit at room temp for 30 minutes before serving. The powdered sugar dusting is optional but adds a pretty finish. Store any leftover chocolate chips or sprinkles in the fridge for up to 6 months to maintain freshness.

Step-by-step instructions for no-bake Rice Krispie treat bars with pudding mix

This twist on classic treats delivers a creamy surprise inside every chewy bite.

In a medium bowl, whisk together the 1 cup softened butter, the 0.5 cup milk, the 1 tsp vanilla extract, and the 0.25 tsp salt until completely smooth. This butter-milk mixture forms the creamy base that sets these treats apart from traditional recipes.

Next, add the 1 box instant vanilla pudding mix to the butter mixture and whisk vigorously for 2-3 minutes until fully dissolved and slightly thickened. You'll notice the mixture will transform from a liquid to a thick, pudding-like consistency. This is your secret weapon for that creamy surprise in every bite.

In a large microwave-safe bowl, melt the 6 cups mini marshmallows in 30-second intervals on high power, stirring between each interval. Be careful not to over-melt—they should be completely melted but still hold their shape when dropped. The mini marshmallows melt more evenly than jumbo ones, creating a smoother texture.

Immediately pour the melted marshmallows over the pudding mixture and stir until fully combined. Add the 0.5 cup chocolate chips and 0.25 cup sprinkles and fold them in gently. The mixture will be thick and gooey—this is exactly what you want. If it seems too thick, you can add 1-2 teaspoons of milk to loosen it slightly.

Lightly grease a 9x13-inch baking dish with the 1 tbsp coconut oil (or use butter if you prefer). Spread the marshmallow-pudding mixture evenly into the prepared pan, pressing down gently with a spatula to create an even layer. This ensures your bars will have consistent thickness and texture throughout.

Sprinkle the 6 cups Rice Krispies cereal evenly over the top, pressing down lightly but firmly. You want the cereal to stick to the marshmallow layer but not so hard that you compact it too much. This layer should cover the entire surface completely, leaving no gaps. The cereal will absorb some of the marshmallow mixture, creating that signature crispy texture.

Refrigerate the pan for at least 4 hours, or until completely firm. This chilling time is crucial—it allows the pudding mixture to fully set and creates that perfect chewy texture. I know it's tempting to cut into them sooner, but patience here makes all the difference.

Once fully set, use a sharp knife to cut the mixture into 16 equal bars. For cleaner cuts, dip the knife in hot water between each slice. The bars should hold their shape when lifted, with a crispy exterior and that creamy surprise inside. If they're too soft when you remove them, return them to the refrigerator for another 15-20 minutes to firm up.

Just before serving, dust the top of each bar with the 0.25 cup powdered sugar using a fine-mesh sieve. This adds a beautiful finish and a subtle sweetness that complements the creamy interior. The powdered sugar also helps prevent the bars from sticking together when you stack them.

Serve immediately while still slightly warm from the refrigerator. These treats are best enjoyed at room temperature, where the contrast between the crispy cereal and creamy filling is most pronounced. Store any leftovers in an airtight container in the refrigerator for up to 5 days, though I doubt they'll last that long!

Essential equipment for this dish

Microwave-Safe Bowl

You’ll need a large microwave-safe bowl with at least a 4-quart capacity to melt the marshmallows. I use a Pyrex glass bowl because it distributes heat evenly and prevents hot spots that can burn the marshmallows.

Avoid plastic bowls—they can warp or melt under high heat. If you don’t have Pyrex, Corelle stoneware is another great option. Just make sure it’s labeled microwave-safe! 🔥

Mixing Tools

A hand mixer or electric whisk is ideal for blending the butter, milk, and pudding mix into a smooth, thick consistency. If you don’t have one, a wooden spoon or rubber spatula will work, but you’ll need to whisk vigorously for 3-4 minutes to fully dissolve the pudding mix.

I love my KitchenAid handheld mixer—it’s lightweight and gets the job done without overmixing. For the marshmallow mixture, a heat-resistant silicone spatula helps scrape every last bit from the bowl.

Greasing Tools

Greasing your pan is key to easy release, and coconut oil is my go-to because it’s flavorless and melts cleanly. Use a small pastry brush or a paper towel to spread a thin layer evenly.

If you prefer butter, soften it slightly and rub it over the pan with your fingers. For extra insurance, I sometimes use parchment paper lined in the pan—just grease the paper first. Avoid nonstick spray; it can leave a residue that makes the bars stick.

Cutting Tools

A sharp chef’s knife or serrated knife is essential for clean cuts. Dip the knife in hot water between slices to prevent the bars from sticking. For even lines, use a metal ruler as a guide.

If you’re cutting into 16 bars, mark your pan with a pencil first for consistency. Pro tip: Chill the knife in the freezer for 5 minutes before cutting—it’ll make slicing even cleaner. 💡

Measuring Cups

Precision matters with these treats, so invest in stainless steel measuring cups for accuracy. For the marshmallows and cereal, use the dry measuring cups that come with a leveling tool. The pudding mix and butter should be measured in liquid measuring cups for smooth consistency.

I keep my OXO Good Grips set on hand—they’re durable and easy to read. If you’re short on time, a kitchen scale works too, but the recipe is designed for volume measurements.

Optional Extras

For the powdered sugar dusting, a fine-mesh sieve ensures an even, professional finish. If you’re adding sprinkles or chocolate chips, a small scoop or spoon helps distribute them evenly. For storage, a clear plastic container with a lid keeps the bars fresh and visible.

Don’t skip the parchment paper if you’re gifting these—it adds a polished touch and prevents sticking. 🎁
