• 113 g (½ cup)salted butter
• 454 g (16 oz)large marshmallows
• 5 ml (1 teaspoon)vanilla
• 1 pinchsalt
• 224 g (8 cups)crisp rice cereal, such as Rice Krispies
• 85 g (½ cup)butterscotch or peanut butter chips, such as Reese’s
• As neededsoftened butter or butter-flavoured cooking spray, for greasing

Instructions

1. 1

   Line the pan

   Line a 33 x 23 cm (13 x 9 inch) baking pan with parchment paper. Grease the parchment with softened butter or butter-flavoured cooking spray.

2. 2

   Brown the butter

   Melt the butter in a large pot over medium-high heat. Continue cooking until golden-brown solid bits appear and the butter smells fragrant.

3. 3

   Melt the marshmallows

   Add the marshmallows and cook over medium heat, stirring constantly until melted. Stir in the vanilla and salt with a wooden spoon.

4. 4

   Stir in cereal

   Take the pot off the heat. Add the crisp rice cereal and butterscotch or peanut butter chips, then stir gently until combined.

   Press into pan

   While the mixture is still workable, spoon it evenly into the prepared pan and spread it into the corners. With lightly greased or slightly wet hands, press it gently into an even layer; pressing too firmly can make the treats hard.

What are brown butter Rice Krispie treats?

They are a variation on American marshmallow-and-crisp-rice cereal bars: melted marshmallows bind the cereal into a chewy, crunchy slab that is cut into portions. This version adds brown butter for a toasted, nutty note and chips for extra sweetness.

The method is simple, but timing matters once the cereal goes in. Working promptly and pressing gently helps keep the finished bars tender rather than dense.

Nutrition and macros by portion

The nutrition label shows one serving as written: 123 calories, 1g protein, 23g carbs, 4g fat.

The crisp rice cereal and marshmallows provide most of the carbohydrates, while butter and the optional chips contribute much of the fat. Protein is modest and comes mainly from the cereal and chips. Pair a bar with fruit and yoghurt or milk for a more balanced snack.

Brown the butter carefully

Watch the butter as it melts and bubbles; the golden-brown flecks and fragrant smell are the cues to move on. The solids can darken quickly, so keep your attention on the pot.

Salted butter seasons the bars from within. The recipe adds only a pinch of extra salt, so taste and adjust only if you know you prefer a saltier sweet.

Melt the marshmallows smoothly

Stir constantly over medium heat so the marshmallows melt evenly and do not catch on the bottom. Once they are melted, take the pot off the heat before adding the cereal.

Stir in the vanilla and salt while the marshmallow mixture is still warm. Gentle mixing after adding the cereal helps coat it without crushing the crisp pieces.

Press for a chewy texture

Spread the mixture into the corners while it is still pliable. Lightly greased or damp hands make it easier to even the surface without sticking.

Use a light touch rather than packing the cereal down. A firmly compressed layer tends to make tougher, denser bars.

Choose your chips

Butterscotch chips give the bars a buttery caramel-like sweetness, while peanut butter chips add a nutty flavour. Either option goes into the warm cereal mixture after the pot comes off the heat.

For a decorative finish, the description suggests adding seasonal sprinkles on top. Add them while the surface is still soft so they can adhere.

Cut and serve

Let the slab set in the pan before cutting it into 30 pieces. A lightly greased knife can help make cleaner cuts through the sticky cereal mixture.

Serve the bars as a lunchbox treat or an easy sweet snack. Their crisp and chewy texture works well alongside fresh fruit or a glass of milk.

Recipe notes & tips

• Have the pan lined and greased before you start melting the butter.
• Keep stirring the butter and watch for golden flecks and a fragrant smell.
• Stir the cereal in gently to keep as much of its crisp texture as possible.
• Work quickly once the cereal is added, as the mixture begins to firm up.
• Use damp or lightly greased hands to spread the mixture without it sticking.
• Press only enough to make an even layer, not a tightly packed one.

Variations

• Seasonal sprinkles: Scatter them over the top while the mixture is still soft.
• Butterscotch chips: Choose these for a sweet, buttery flavour.
• Peanut butter chips: Swap in these chips for a nutty twist.
• Mixed chips: Use half butterscotch and half peanut butter chips for both flavours.
• Smaller squares: Cut the slab into more pieces for smaller treats.

Common mistakes to avoid

• Butter browning too far: Take the pot off the heat once the flecks are golden and fragrant.
• Marshmallows catching: Stir constantly as they melt over medium heat.
• Cereal crushed: Fold it in gently rather than stirring vigorously.
• Mixture setting in the pot: Spoon it into the pan promptly after combining.
• Bars turning firm: Press the mixture lightly instead of compacting it.
• Sticky hands: Lightly grease or dampen your hands before spreading the mixture.

How to store

Store the cut treats in an airtight container at room temperature and enjoy within about 3 days for the best texture. Keep them separated with parchment if stacking. They are best eaten as they are rather than reheated.
