Blueberry Crumble Cheesecake Bars (Printable Version)

# What You'll Need:

→ Crust

01 - 15 graham crackers
02 - 1 large egg white
03 - 75 g unsalted butter, melted
04 - 8 g granulated sugar
05 - 1 g kosher salt
06 - cooking spray

→ Filling

07 - 450 g cream cheese, room temperature
08 - 1 large egg, room temperature
09 - 1 large egg yolk
10 - 50 g granulated sugar
11 - 5 ml pure vanilla extract

→ Blueberry Layer

12 - 280 g fresh or frozen blueberries
13 - 60 ml blueberry jam

→ Crumb Topping

14 - 90 g all-purpose flour
15 - 70 g unsalted butter, melted
16 - 45 g dark brown sugar
17 - 2 tsp finely grated lemon zest
18 - 1 g kosher salt

# Step-by-Step Directions:

01 - Preheat oven to 163°C and position rack in center. Spray a 23 cm x 23 cm baking dish with cooking spray and line with parchment paper, leaving a 5 cm overhang on two opposite sides.
02 - Pulse graham crackers, egg white, melted butter, sugar, and salt in a food processor until fine crumbs form. Press evenly into bottom of prepared pan. Set aside.
03 - Beat cream cheese in a stand mixer on medium-high speed until fluffy, 1 to 2 minutes. Add sugar and mix until combined. Incorporate the whole egg and reserved egg yolk one at a time, blending well after each addition. Add vanilla extract and whisk to integrate fully. Pour mixture over crust.
04 - Gently mash fresh blueberries to retain some texture and fold in blueberry jam. Distribute dollops of blueberry mixture over the cream cheese filling.
05 - Whisk together flour, brown sugar, melted butter, lemon zest, and salt until soft crumbs form. If mixture feels wet or warm, refrigerate until firm. Sprinkle evenly over blueberry layer.
06 - Bake for approximately 30 minutes until edges are firm, center retains slight jiggle, and topping is lightly golden. Allow to cool in pan for 30 minutes.
07 - Refrigerate bars until fully cold, at least 2 hours or overnight. Use parchment overhang to lift bars from pan and cut into portions.

# Helpful Notes:

01 - If cream cheese is too cold, soften by microwaving in short bursts or mixing with sugar to expedite softening.
02 - Do not pre-bake crust; binding with egg white and butter is sufficient for structure.
03 - Crumble topping benefits from refrigeration if too warm before baking to maintain texture.
04 - Bars can be stored refrigerated in airtight container up to 3 days.
