07 - Drizzle the peanut butter protein mixture over the pressed base.
08 - Warm the jelly slightly to loosen, then drop spoonfuls over the top. Use a knife or skewer to swirl the jelly and peanut butter drizzle decoratively.
09 - Chill in the refrigerator for at least 40 minutes, or until set.
10 - Lift out of the pan using parchment, cut into 12 bars, and enjoy.

# Expert Advice:

01 -
  • They taste like the Rice Krispie treats you loved as a kid, but your body actually thanks you for eating them.
  • Minimal cooking involved, and the payoff is 12 bars that beat any store-bought protein snack by miles.
  • Perfect for meal prep chaos—just grab one on your way out the door and feel like you have your life together.
02 -
  • Low heat is everything when melting the peanut butter and honey—high heat will cause separation and you'll end up frustrated.
  • The protein powder actually changes the texture, so don't skip it thinking the bars will turn out fine anyway—they need it to hold together properly.
03 -
  • Slightly warm your jelly or jam before drizzling—it flows so much better and creates prettier swirls that actually stay where you put them.
  • Use a bench scraper or offset spatula to press the cereal mixture into corners evenly; regular spoons leave air pockets that compromise the structure.
