Description
Pumpkin rice krispie treats with a chewy marshmallow bite and pumpkin pie spice, shaped into little pumpkins and finished with pretzel stems.
Ingredients
Cereal Treat Base
- 6 tablespoons salted butter
- 16 ounces (454 g) fresh mini marshmallows
- 2 teaspoons vanilla extract
- 1½–2 teaspoons pumpkin pie spice
- A pinch of fine sea salt
- 8 cups crisp rice cereal
Pumpkin Stems and Optional Decorations
- 24 short pretzel pieces for stems
- Orange gel food coloring, optional
- A small amount of green icing or melted green candy for leaves or vines, optional
- A little neutral oil, butter, or cooking spray for greasing tools and hands
Optional Real-Pumpkin Addition
- 2–3 tablespoons plain pumpkin purée, cooked down to approximately 1 tablespoon before adding
Instructions
- Get Everything Ready. Line a tray with parchment. Measure the cereal into a bowl and set out the pretzel stems, decorations, and remaining ingredients. Have a little butter or neutral oil ready for greasing your hands.
- Reduce the Optional Pumpkin. If using purée, put 2–3 tablespoons in a small skillet over medium-low heat. Stir until thickened and reduced to about 1 tablespoon, approximately 2–3 minutes or longer as needed. Set aside to cool briefly.
- Melt the Butter and Marshmallows. In a large saucepan over low heat, melt the butter. Add the marshmallows and stir until smooth. Remove the pan from the heat promptly.
- Add the Flavorings. Mix in the vanilla, pumpkin pie spice, and salt. Stir in the optional tablespoon of reduced pumpkin. Add a small amount of orange gel color if desired.
- Coat the Cereal. Add the 8 cups of cereal and fold with a wide spatula until there are no dry pockets. Keep the mixture off the heat and avoid crushing the cereal.
- Shape the Pumpkins. Let the mixture cool just enough to handle comfortably. Lightly grease your palms and divide the batch into 24 roughly equal portions. Shape gently into balls, flatten the bottoms, and press shallow ridges around the sides. Add a short pretzel stem and optional green decoration to each.
- Let the Shapes Set. Leave the pumpkins on the lined tray for about 10–15 minutes, or until they hold their shape. Cool fully before packing.
- Store the Appropriate Version. Once fully cooled, pack the spice-only treats airtight in a cool, dry place and plan to serve within two days. Make the reduced-purée version close to serving time and refrigerate its leftovers. Any refrigerated topping also changes the storage requirements.
Notes
- Pumpkin pie spice supplies the main flavor. Purée, orange color, and green decorations are optional.
- Divide the batch into 24 portions for 24 small pumpkins. Larger portions will produce fewer treats.
- Measure marshmallows by weight because cup measurements vary between brands.
- Add approximately 1 tablespoon of purée after reducing, rather than 2–3 tablespoons straight from the can.

Ingredients for Pumpkin Spice Rice Krispie Treats
First, get out a large saucepan, a spatula and a tray lined with parchment. Take a bowl and put the cereal in it, ready to put in the marshmallows when they are melted. You have only a brief window of time to mix and shape while all is pliable.

| Ingredient | Amount | What matters here |
|---|---|---|
| Salted butter | 6 tablespoons | Melt over low heat before adding the marshmallows. |
| Mini marshmallows | 16 ounces | Check the bag weight rather than relying on a cup conversion. Use a fresh, soft package. |
| Crisp rice cereal | 8 cups | Taste a few pieces first. Stale cereal will still taste stale after coating. |
| Vanilla extract | 2 teaspoons | Stir in after taking the marshmallow mixture off the heat. |
| Pumpkin pie spice | 1½–2 teaspoons | Start at the lower amount for a milder batch. |
| Fine sea salt | A pinch | The butter is already salted, so keep this addition small. |
For the stems, have 24 short pretzel pieces ready. Orange gel color (optional) Green icing (optional) The pumpkin spice flavor is not affected by keeping the pumpkins their natural color.
Pumpkin Spice or Real Pumpkin?
Pumpkin pie spice adds warm flavor without extra moisture. For a touch of real pumpkin, use plain purée.
- Start with: 2–3 tablespoons pumpkin purée.
- Reduce: Cook until only about 1 tablespoon remains.
- Add: Stir into the marshmallow mixture before adding the cereal.
Tip: Avoid adding purée straight from the can. Excess moisture can make the treats soggy.
If you want a dessert that uses more purée, no bake pumpkin lush uses a full 15-ounce can in a layered dessert.
How to Make Pumpkin Rice Krispie Treats
1. Prepare the Tray and Any Optional Pumpkin
Line a tray with parchment and set out the pretzel pieces and green decorations. Have a little butter or neutral oil ready for your hands when it is time to shape the mixture.
If using purée, put 2–3 tablespoons in a small skillet over medium-low heat. Stir as it cooks down to approximately 1 tablespoon, usually about 2–3 minutes. Use the reduced amount as your guide; different pans and purées may take longer. Set it aside to cool briefly while you melt the butter.
2. Melt the Marshmallows over Low Heat
Melt the butter in the large saucepan over low heat. Add the marshmallows and stir, reaching into the corners of the pan, until they have melted into the butter. Take the pan off the burner as soon as the mixture is smooth.

Stir in the vanilla, pumpkin pie spice, and salt. Add the optional reduced purée now, if using. Mix in a small amount of orange gel color at this stage if you want an even orange color without extra stirring after the cereal goes in.
3. Fold in the Cereal
Add the measured cereal to the warm marshmallow mixture. With a wide spatula, lift the mixture from the bottom and turn it over until the dry pockets disappear. Keep the cereal pieces as intact as you can.
Work steadily while the marshmallow coating is still flexible. Having the tray and decorations ready means you can move straight from mixing to shaping.
4. Form the Pumpkin Shapes
Let the mixture cool just enough to touch comfortably, keeping it pliable. Lightly grease your palms and divide the batch into 24 roughly equal portions. Gently bring each portion into a ball and flatten its bottom so it can sit upright. Avoid squeezing it tightly.

Press shallow vertical lines around the sides, insert a short pretzel piece as a stem, and add an optional green icing curl. Work while the mixture is flexible. If children are helping, an adult should handle the saucepan and check the temperature before shaping.
5. Let the Pumpkins Set
Place the formed pumpkins on the lined tray for about 10–15 minutes, or until they hold their shape when picked up. Let them cool fully before packing them in a covered container.
Pumpkin Shaped Rice Krispie Treats: Decorating Tips
A few simple touches make these little pumpkins fun and festive.
- Keep sizes even: Divide the mixture into 24 portions and use the first pumpkin as a guide. Larger treats will reduce the yield.
- Add orange color: Mix a little orange gel food coloring into the melted marshmallows before adding the cereal.
- Make simple stems: Use short pretzel pieces for a pumpkin-like finish.
- Add green details: Pipe small leaves or vines with green icing.

Why Are My Treats Hard, Sticky, or Falling Apart?
Check when the problem appeared. A loose mixture straight from the saucepan needs cooling; cereal that has lost its crunch after an added liquid is a different issue.
| Problem | What may have happened | What to do |
|---|---|---|
| The cooled pumpkins are dense and difficult to bite | The marshmallow mixture overheated or the portions were squeezed tightly | Use low heat and shape gently for the next batch. Extra decoration will not correct a hard base. |
| The pumpkins fall apart when lifted | They have not finished setting, or some cereal was left uncoated | Give them more time on the tray. On the next batch, fold thoroughly and scrape the bottom of the pot. |
| The cereal becomes soft or soggy | Unreduced purée, too much purée, or another liquid was added | Keep the optional pumpkin to 1 tablespoon after reducing. Chilling will not make wet cereal crisp again. |
| The mixture sticks during shaping | It is very warm or your hands need a little grease | Let it cool enough to handle and lightly grease your palms. Avoid adding water to the mixture. |
| The flavor seems flat | The cereal or spice blend may be stale | Taste and check ingredients before cooking, and store finished treats airtight. |
Variations and Ingredient Checks
Optional Pan Bars
For pumpkin rice krispie bars, gently press the warm mixture into a greased, parchment-lined 9×13-inch pan. Let set for 20–30 minutes, then cut into 24 squares.
White Chocolate Drizzle
Drizzle cooled treats with melted white chocolate or suitable candy coating. Follow the package instructions and let it set before stacking. Keep the drizzle light to preserve the crispy texture.
Pecan Topping
Press a few finely chopped toasted pecans onto the shaped pumpkins before they set. Keep nuts optional when serving guests.
Gluten-Free Cereal and Decorations
Rice cereal isn’t always gluten-free because some brands contain barley malt. The Celiac Disease Foundation explains why checking labels matters.
Choose gluten-free cereal when needed, and check the marshmallows, spices, pretzels, and decorations too. Texture may vary between brands.
Marshmallows and Vegetarian Labels
Many marshmallows contain animal-derived gelatin, so check the label before calling these treats vegetarian.
Gelatin-free marshmallows are an option, but they may melt differently. Follow the manufacturer’s instructions for the best results.
