# What You’ll Need:

→ Base

01 - 4 cups crisped rice cereal
02 - 1 cup creamy peanut butter
03 - 1/2 cup honey or maple syrup
04 - 1/4 cup vanilla or unflavored protein powder
05 - 1/4 teaspoon fine sea salt
06 - 1 teaspoon vanilla extract

→ Toppings

07 - 1/3 cup peanut butter for drizzle
08 - 2 tablespoons vanilla or unflavored protein powder for drizzle
09 - 2 tablespoons milk (dairy or plant-based)
10 - 1/3 cup strawberry or grape jelly, slightly warmed

# Step-by-Step Guide:

01 - Line an 8x8-inch baking pan with parchment paper, allowing overhang on edges for convenient removal after setting.
02 - In a large saucepan, gently heat 1 cup peanut butter and honey over low heat, stirring continuously until smooth and fully combined.
03 - Remove from heat and stir in vanilla extract, salt, and 1/4 cup protein powder until completely incorporated with no visible lumps.
04 - Add crisped rice cereal to the peanut butter mixture and fold until every piece is evenly coated.
05 - Transfer the mixture to the prepared pan and press firmly and evenly across the entire surface using a spatula.
06 - In a small bowl, whisk together 1/3 cup peanut butter and 2 tablespoons protein powder, adding milk gradually until a thick, pourable consistency is achieved.
07 - Drizzle the peanut butter protein mixture evenly across the pressed base layer.
08 - Spoon warm jelly over the peanut butter drizzle, then use a knife or skewer to create decorative swirls throughout, blending the layers visually.
09 - Refrigerate for at least 40 minutes until the mixture is completely set and firm to the touch.
10 - Using the parchment overhang, lift the entire block from the pan, transfer to a cutting surface, and cut into 12 equal bars with a sharp knife.

# Expert Tips:

01 -
  • They taste like a fancy homemade candy bar but deliver real protein and actually keep you satisfied past mid-morning.
  • No oven required—just a saucepan and your hands, so they're perfect for chaotic weekday prep.
  • The swirled jelly and peanut butter drizzle makes them look intentional and beautiful even if you're rushing.
02 -
  • Don't skip warming the jelly—cold jelly is stubborn and won't swirl, it'll just sit there like you didn't even try.
  • The protein powder in the drizzle needs that milk to stay pourable, so add it slowly and taste-test a tiny bit if you're nervous about the flavor balance.
03 -
  • The parchment overhang is non-negotiable—it's the difference between lifting the whole block out cleanly and wrestling with it.
  • Don't skip the protein powder in the drizzle even if you're tempted—it's what keeps it from being just peanut butter on top and gives these bars their whole identity.
