Ingredients

Cereal Base

• 4 cups crisp rice cereal
• 1 1/2 cups mini marshmallows
• 1/4 cup unsalted butter
• 1/4 cup creamy peanut butter
• 1/2 teaspoon vanilla extract
• Pinch of salt

Protein Drizzle

• 1/2 cup vanilla protein powder
• 1/3 cup creamy peanut butter
• 2 tablespoons unsweetened almond milk (or milk of choice)
• 2 tablespoons maple syrup or honey

Jelly Swirl

• 1/3 cup fruit jelly or jam (strawberry, raspberry, or grape work well)

Instructions

Step 1

Line an 8x8-inch square baking pan with parchment paper, leaving overhang for easy removal.

Step 2

In a large saucepan over low heat, melt the butter and peanut butter together. Add marshmallows and stir until completely melted and smooth. Remove from heat and stir in vanilla and salt.

Add the crisp rice cereal to the mixture and fold until evenly coated.

Step 4

Press the mixture firmly and evenly into the prepared pan.

In a small bowl, whisk together protein powder, peanut butter, almond milk, and maple syrup until smooth and pourable. Adjust milk for consistency if needed.

Step 6

Drizzle the protein mixture evenly over the pressed cereal layer.

Step 7

Spoon small dollops of jelly over the top. Use a knife or skewer to gently swirl the jelly and protein drizzle together for a marbled effect.

Step 8

Chill in the refrigerator for at least 1 hour, or until set.

Step 9

Lift the bars out using the parchment overhang and cut into 12 squares.
