Brown Butter Rice Krispie Treats
Not rated yet. Be the first.
Brown butter makes the kitchen smell warm and nutty, and flaky salt on top keeps the sweetness in check. Press lightly, save a handful of marshmallows for the end, and the squares stay gooey.
The short version
Brown the butter, melt most of the marshmallows into it off the heat, stir in vanilla, salt and the cereal, then fold in the last marshmallows. Press gently into a 9×13-inch pan, cool 30 minutes, cut. No oven, about 45 minutes.
What makes ours better
small changes, very loud compliments
-
Brown the butter. Five minutes in a pot turns the butter nutty and toffee-like, and the marshmallow sweetness finally has something to push against.
-
Salt in the mix and on top. A pinch stirred in and a few flakes on top keep these from tasting flat and sugary, and the crunch of the flakes is a pleasure of its own.
-
Save a handful of marshmallows for the end. Marshmallows folded in after the cereal stay in soft, stretchy pockets instead of melting away, so every bite is gooey.
-
Press lightly, don't pack. Packing the pan crushes the cereal into a dense, hard bar. A light press with greased hands keeps the treats chewy and airy.
yes, all of the butter
Steps
go slow. the good part can’t be rushed.
-
Butter the pan
Grease a 9×13-inch pan with butter, or line it with parchment and grease the parchment. Measure the cereal into a very large bowl or have a big pot ready, so you have room to stir.
-
Brown the butter
Melt the butter in a large, wide pot over medium heat. It will foam, then go quiet. Keep stirring until you see golden-brown flecks on the bottom and it smells like toffee, 4 to 6 minutes. Take the pot off the heat at once.
Pull it when the first flecks turn tan. The butter keeps cooking in the hot pot and goes from brown to burnt fast.
About 5 min. Cook mode has a timer for this step.
-
Melt the marshmallows
Stir the vanilla and kosher salt into the butter. Add all but a heaping cup of the marshmallows. Stir over low heat until almost all of them melt into a smooth, glossy mixture, 2 to 3 minutes. Take the pot off the heat.
Keep the heat low. Hot marshmallow turns tough once it cools.
-
Stir in the cereal
Add the cereal and stir with a greased spatula until every piece is coated. Let the mixture cool for 1 minute, then fold in the reserved marshmallows so they stay partly whole.
-
Press into the pan
Scrape the mixture into the pan. With a greased spatula or a sheet of parchment, press it into an even layer, just firm enough to hold together. Sprinkle the flaky salt over the top.
Light pressure only. Pushing hard gives you hard treats.
-
Cool and cut
Let the pan sit for 30 minutes at room temperature until the treats are set. Cut into 16 squares with a greased knife.
About 30 min. Cook mode has a timer for this step.
Good to know
the stuff I’d tell you over the phone
- Use a fresh box of cereal. Stale cereal makes limp treats, and nothing else in the pot can fix that.
- Mini marshmallows melt faster and more evenly than large ones. If you only have large, 40 of them (about 10 ounces) will do.
- Use salted butter if you like, and cut the kosher salt in the mix to ¼ teaspoon.
- Don't refrigerate them to speed things up. The cold makes them stiff.
- Storage. Airtight at room temperature, with parchment between layers, 3 days. Freeze wrapped squares for up to 2 months and thaw at room temperature for an hour.
Questions, answered
asked and answered at the kitchen counter
Why are my Rice Krispie treats hard?
Three culprits. The marshmallows cooked too hot, the pan was packed down too firmly, or there was too much cereal for the marshmallows. Keep the heat low, press lightly, and measure the cereal with a spoon, not by packing the cup.
Do I have to brown the butter?
No. Plain melted butter gives you a classic treat. Browned butter gives it a toasty, caramel edge that makes people ask what you did.
Can I use large marshmallows?
Yes. Use about 40 large marshmallows for 10 ounces, and expect them to take a few minutes longer to melt. Stir over low heat and take your time.
Can I make Rice Krispie treats ahead?
Yes. Make them up to 3 days ahead and keep them airtight at room temperature. They stay soft for the whole stretch when they're wrapped well.
Can I use a smaller pan for thicker treats?
Yes. A 9×9-inch pan gives you thick, extra-chewy squares. Press them gently and cut into 12 pieces.
