White Chocolate Cranberry Rice Krispie Treats

These white chocolate cranberry Rice Krispie treats are the old marshmallow cereal bars with dried cranberries folded in, a little orange zest on top and a drizzle of melted white chocolate. They take about 15 minutes of hands-on time, set in about 30 more, and one 8×8 or 9×9 pan cuts into 16 squares.

The soft, chewy texture comes from two habits: low heat for the marshmallows, and a light hand when you press the mixture into the pan.

How Much Marshmallow for 6 Cups of Rice Krispies?

One 10 ounce bag of mini marshmallows and 3 tablespoons of butter for 6 cups of Rice Krispies. That ratio gives a bar that holds together but still pulls apart with a little stretch. Add ¾ cup dried cranberries, 4 ounces of white chocolate for the drizzle, ½ teaspoon vanilla, a pinch of salt and the zest of 1 orange if you like.

Fresh marshmallows matter. More than you would think. A bag that has gone dry and firm melts stiff, coats the cereal unevenly and sets harder. Use real vanilla too. Nothing is baked, so you taste it. The pinch of salt does not make the bars salty; it keeps all that sugar from tasting flat.

Melting the Marshmallows Low So the Bars Stay Soft

Line the pan with parchment, leave an overhang to lift the bars out, and grease it lightly. Melt the butter in a large saucepan over low heat. Add the marshmallows and stir constantly until they are completely melted and smooth, then stir in the salt and vanilla.

Keep the heat low. The whole time. Marshmallow cooked too hot or too long turns into a firmer candy, and the treats are hard by the next day. As soon as the mixture is smooth, take the pan off the heat and stir in the cereal until every piece is coated.

This is the same base as my peanut butter Rice Krispie treats, so if you have made those, you already know the feel. Baked, the cereal behaves differently: in my Rice Krispie chocolate chip cookies it adds crunch to a chewy dough.

Dried Cranberries and Orange Zest: How Much and When

Fold in the ¾ cup dried cranberries right after the cereal, while the mixture is still warm and loose. Keep a small handful back for the top. Chop large or dry cranberries first. Smaller pieces spread through every square, and the knife goes through them cleanly instead of dragging.

Why cranberries? They stay tart. Raisins taste sweet against the marshmallow and fade into the background.

For cranberry orange Rice Krispie treats, zest 1 orange straight over the pressed bars while they are still warm, then press the zest and the reserved cranberries in lightly so they stick. Zest added at this point stays fragrant. No orange? Skip it. Nothing else changes. The same cranberry, orange and white chocolate trio runs through my cranberry bliss bars and white chocolate cranberry cookies.

How Hard Should You Press Rice Krispie Treats?

Firmly enough to make a flat, even layer. No harder.

Tip the mixture into the pan and press it out with a buttered spatula or a sheet of wax paper, working quickly while the marshmallow is warm. Packing it down squeezes the air out from between the puffs, and a squeezed bar is dense and tough to bite. In an 8×8 pan the squares come out a little taller; a 9×9 pan gives thinner bars.

White Chocolate or Yogurt Chips for the Drizzle?

Use real white chocolate. A chopped bar or good chips both work. It melts smooth and sets firm but soft on top of the bars. Yogurt chips look the same in the bag, but they do not melt into a pourable drizzle; they clump and catch quickly, and the coating tastes heavier.

Melt the 4 ounces in a microwave-safe bowl in 30 second bursts, stirring after each one. Stop while a few small lumps remain and stir until they disappear. White chocolate scorches easily, and once it turns thick and grainy it will not drizzle. Spoon it over the bars in thin lines, or pipe it from a bag with the corner snipped.

Setting, Slicing and a Christmas Tray

Let the bars set for at least 30 minutes at room temperature, or 10 minutes in the fridge, until the chocolate is firm. Lift the slab out by the parchment and cut a 4 by 4 grid for 16 squares, or cut larger pieces on the diagonal for 12 triangles. Wipe the knife with a little butter if it starts to stick.

They sit well on a cookie tray next to white chocolate Rice Krispie balls and Rice Krispie Christmas puddings, which use the same cereal in a different shape. For more no-bake ideas, see my Christmas desserts.

Keeping the Squares Soft for Gift Tins

Keep them airtight. Store the squares in a sealed container at room temperature for up to 3 days, with wax paper between layers. Keep them out of the fridge unless your kitchen is warm. Cold air dries the marshmallow and the bars turn stiff.

For gifts, make them the day before and wrap each square in parchment or a cellophane bag. They also freeze for up to 6 weeks, layered with wax paper in a sealed container. Thaw them on the counter for about 15 minutes. The white chocolate can lose a little shine after freezing, but the texture comes back.

Cranberry Rice Krispie Treat Questions

Can I add dried cranberries to plain Rice Krispie squares?

Yes. Fold ¾ cup dried cranberries into any 6 cup batch right after the cereal is coated, while the mixture is still warm.

Can I use large marshmallows instead of mini?

Yes. A 10 ounce bag of regular marshmallows works the same way; it just takes a minute or two longer to melt on low heat.

Can I use fresh cranberries?

No. Fresh cranberries are hard, very sour and wet, and they make the cereal soggy. Use dried ones here and save fresh berries for sauce or baking.
