how to make Lemon Condensed Milk Fridge Slice

Ingredients

2 cups crushed plain biscuits or graham crackers
1/2 cup unsalted butter, melted
14 oz sweetened condensed milk
1/2 cup fresh lemon juice
1 tbsp lemon zest
1/2 cup shredded coconut (optional)

Directions

Place biscuits in a food processor and pulse until fine crumbs form. Alternatively, crush them in a sealed bag using a rolling pin.
Pour melted butter over the biscuit crumbs and mix until the texture resembles wet sand.
Line an 8×8-inch pan with parchment paper. Press the crumb mixture firmly into the base using the back of a spoon or a flat-bottomed glass.
Refrigerate the base for 20–30 minutes to firm up.
In a bowl, whisk sweetened condensed milk with fresh lemon juice until thickened.
Stir in lemon zest and shredded coconut if you are using it.
Pour the lemon filling over the chilled base and spread evenly with a spatula.
Refrigerate for at least 3–4 hours or overnight until fully set.
Lift from the pan using the parchment overhang and slice into squares using a warm, clean knife.
