Why You’ll Love These Pumpkin Spice Krispie Treats
This is one of those recipes that is almost impossible to mess up. You melt the butter and marshmallows, add the pumpkin spice, stir in the cereal and press everything into a tray.
A few reasons to try them:
- Ready to prepare in around 10 minutes
- No baking required
- Only a few simple ingredients
- Easy to make for parties or gatherings
- Full of warm autumn flavour
- Kids can help make them too
The pumpkin pie spice adds a lovely mix of cinnamon, nutmeg, ginger and cloves without making the treats taste too strong.
Ingredients
You only need a few ingredients to make a batch:
- 6 cups Rice Krispies cereal
- 10 oz mini marshmallows
- 4 tablespoons butter
- 1 teaspoon pumpkin pie spice
- ½ teaspoon vanilla extract
- A few drops of orange food colouring, optional
- Melted white chocolate for drizzling, optional
How To Make Pumpkin Spice Krispie Treats
Start by lightly greasing a 9 x 13-inch baking dish or lining it with parchment paper.
Add the butter to a large saucepan and melt it over low to medium heat. Once melted, add the marshmallows and keep stirring until they are completely melted and smooth.
Stir in the pumpkin pie spice and vanilla extract. If you want your treats to have more of an autumn orange colour, you can add a couple of drops of orange food colouring too.
Remove the saucepan from the heat, add the Rice Krispies and gently stir until all of the cereal is coated in the marshmallow mixture.
Transfer everything into the prepared baking dish and gently press it into an even layer. Try not to squash the mixture down too firmly because this can make your Krispie treats hard instead of soft and chewy.
Leave them to cool for around 20 to 30 minutes before cutting them into squares.
Don’t Press Them Too Hard
One of the easiest ways to ruin homemade Krispie treats is packing the mixture too tightly into the tray. You only need to gently press everything into place.
A buttered spatula works well, or you can place a sheet of parchment paper over the top and use your hands to lightly level the mixture.
For softer, chewier treats:
- Keep the heat fairly low when melting the marshmallows
- Remove the pan from the heat as soon as everything has melted
- Don’t overmix the cereal
- Don’t pack the mixture tightly into the tray
Can You Add Real Pumpkin?
You can add pumpkin puree to Rice Krispie treats, but it changes the texture because pumpkin contains quite a lot of moisture.
For this quick recipe, I prefer using pumpkin pie spice instead. You still get that familiar autumn flavour while keeping the cereal crispy and the marshmallow mixture chewy.
Easy Ways To Decorate Them
You can leave these treats completely plain, but a few simple decorations make them look much more festive.
For Halloween, try orange and black sprinkles. For Thanksgiving or a general autumn dessert, drizzle a little melted white chocolate over the top and finish with a very light sprinkle of pumpkin pie spice.
You could also cut them into smaller bite-sized squares and add them to a dessert platter alongside brownies, cookies and other autumn treats.
How To Store Them
Keep your Pumpkin Spice Krispie Treats in an airtight container at room temperature. They are best eaten within about 2 to 3 days while they are still soft and chewy.
I wouldn’t recommend putting them in the fridge because colder temperatures can make the marshmallow mixture firm and change the texture.
