Let’s Make it together
Melt the Butter and Marshmallows: In a large saucepan over medium heat, melt the butter until bubbly. Add in marshmallows and stir continuously until they’re completely melted and smooth.
Add Peanut Butter and Vanilla: Remove from heat and stir in the peanut butter and vanilla extract until fully combined with the marshmallow mixture. Your kitchen will smell amazing right about now!
Mix in Rice Krispies: Gradually fold in the Rice Krispies, ensuring every piece gets coated in that sweet peanut buttery goodness. Be gentle to keep that delightful crunch intact.
Press into a Pan: Transfer the mixture into a greased 9×13 inch pan. With slightly damp hands or using parchment paper, press down firmly until evenly spread.
Cool and Cut: Allow your treats to cool at room temperature for about 30 minutes before cutting them into squares. This part is always tough—I recommend snacking on any uneven edges!
