Fancy Rice Krispy Treats

Billionaire's Krispy Bars

Chewy, brown butter-laced rice krispy treats, gooey salted caramel, rich peanut butter ganache. These layered sweets take millionaire bars to a whole new level. The best part? You don’t even have to turn on the oven.

Billionaire's Krispy Treats

I’ve had some version of these on my mental to-do list for awhile now, but it was my dad’s upcoming birthday that finally turned them into a (very tasty) reality. He’s a die-hard peanut butter addict (he adds it to everything from french toast to pasta) and after 20-some-odd years I’ve run the PB dessert gamut: cheesecakes, cupcakes, ice creams, cookies, brownies, even pies.

I’m sure he wouldn’t have minded (or probably even noticed) a repeat, but I have a personal aversion to baking the same thing twice, so it was time for something new. And these were the perfect solution.

Peanut Butter


For the Rice Krispy treats: 

  • 4 tbsp butter
  • 4 c mini marshmallows
  • 5 c Rice Krispies

For the salted caramel: 

  • 1/2 c unsalted butter
  • 1/2 c sugar
  • 2 tbsp light corn syrup
  • 1 (14 oz) can sweetened condensed milk
  • 1 tsp sea salt
  • 1 tsp vanilla

For the peanut butter ganache:

  • 6 oz semisweet chocolate chips
  • 1/2 c heavy cream
  • 1/4 c peanut butter


  1. Lightly grease a 13 x 9 x 2″ casserole dish.
  2. Make the Rice Krispy treats: Brown the butter in a large nonstick saucepan over medium-low heat, being careful not to let it burn. Add marshmallows and stir until completely melted. Stir in Rice Krispies, and pour mixture into casserole dish. Press with wax paper to even out the surface.
  3. Make the caramel: Combine butter, sugar, corn syrup, and sweetened condensed milk in a small saucepan over medium heat, stirring occasionally, until butter is melted.  Increase to medium-high and bring mixture to a boil.  Reduce to a simmer, stirring constantly until the mixture thickens and becomes caramel-colored. Add vanilla and sea salt and stir to incorporate. Pour over Rice Krispy layer, spread evenly with a spatula, and chill in the fridge until set (at least two hours).
  4. Make the ganache: Melt chocolate chips, cream, and peanut butter in a small saucepan over low heat, stirring constantly. Pour over cooled caramel layer and chill at least 30 min.
  5. Slice, serve, and try not to lick the pan (in public).
