  • Cream cheese: eight ounces Go for full fat and room temperature for a creamy finish

  • Unsalted butter: one cup melted Provides depth and structure Use high quality butter for the richest crust
  • All purpose flour: one cup Measured carefully to maintain crust consistency Use the spoon and level method

My grandmother always insisted on tasting the rhubarb filling before baking to adjust the sweetness I still follow her advice and it always pays off especially with early season rhubarb

Storage Tips

Store bars in an airtight container in the refrigerator for up to five days The crust softens and the topping firms up creating an ideal texture If freezing wrap each square in parchment and seal in a freezer bag for longer storage Thaw in the fridge overnight before serving

Ingredient Substitutions

For a milder bar try replacing half the rhubarb with strawberries A bit of lemon zest stirred into the cream cheese adds brightness If you are baking gluten free substitute with a one to one gluten free flour blend and certified gluten free oats

Serving Suggestions

Serve well chilled as a refreshing dessert on warm afternoons A dusting of powdered sugar adds a pretty finish or garnish with a thin slice of fresh strawberry alongside a cup of hot tea
