Ingredients
  

For the Krispie base
  • 4 tbsp butter
  • 1 bag (10 oz) mini marshmallows
  • 1 tbsp lemon zest
  • 6 cup Rice Krispies cereal
For the lemon cheesecake layer
  • 8 oz cream cheese softened
  • 1 cup powdered sugar
  • 2 tbsp fresh lemon juice
  • 1 tbsp lemon zest
  • 1 tsp vanilla extract
  • 1 cup whipped topping folded in
For the topping
  • 0.5 cup white chocolate chips melted
  • 1 lemon zest extra for garnish

Equipment

  • 1 sheet pan

Method
 

Prep the pan
  1. Line a 9x13 pan with parchment paper and spray lightly so the bars lift out cleanly later.
Make the Krispie base
  1. Melt the butter in a large pot over medium-low heat until glossy, about 2 minutes, stirring to prevent browning (visual cue: smooth melted butter).
  2. Add the mini marshmallows and stir continuously until fully melted, about 2–3 minutes, then remove from heat (visual cue: no unmelted lumps).
  3. Stir in the lemon zest and mix until evenly distributed, about 30 seconds (visual cue: bright specks throughout the sticky mixture).
  4. Fold in the Rice Krispies cereal and stir until completely coated, then press the mixture firmly into the prepared pan (visual cue: even, compact layer).
  5. Cool the Krispie base until set to the touch, about 10 minutes (visual cue: less sticky and holds shape when pressed gently).
Make the lemon cheesecake layer
  1. Beat the cream cheese, powdered sugar, lemon juice, lemon zest, and vanilla until smooth, about 2–3 minutes (visual cue: thick, glossy, lump-free cream).
  2. Fold in the whipped topping until no streaks remain, about 1 minute (visual cue: lightened texture with consistent color).
  3. Spread the lemon cheesecake layer evenly over the cooled Krispie base using a spatula (visual cue: level top with no gaps).
Finish and chill
  1. Melt the white chocolate chips and drizzle in a zigzag pattern over the top (visual cue: thin lines that sit on the surface).
  2. Scatter extra lemon zest over the drizzle, then refrigerate for 1 hour (visual cue: set layer that firms up for clean cutting).
  3. Cut into 16 bars only after chilling, using straight pressure for tidy squares (visual cue: defined layers).

Notes

For the smoothest cheesecake layer, make sure the cream cheese is truly softened before beating. Refrigerate bars in an airtight container up to 3 days; freeze up to 1 month and thaw overnight in the fridge. For a dairy-reduced option, use reduced-fat cream cheese and dairy-free whipped topping if you want a lighter cheesecake layer while keeping the same method.
