My kids always race to snag the first corner piece toasted coconut and the caramelized milk at the edge is their absolute favorite when my grandma visited she was amazed I could get them to eat rhubarb and even asked for the recipe herself

Flavor Boosters

Let bars cool completely before storing so the crust stays crisp Cover tightly with plastic wrap or store in an airtight container They will keep well at room temperature for up to three days or in the fridge for up to a week

Serving Suggestions

Serve with a dollop of whipped cream for a fancy touch Enjoy as an afternoon snack with tea or share at potlucks Cut into smaller squares for holiday dessert platters I also love packing these in lunch boxes for a cheerful midday treat

Creative Twists

If you do not have pecans or walnuts try using almonds or leaving out nuts altogether for a nut free version Swap white chocolate chips with milk or dark chocolate for a richer taste Out of fresh rhubarb frozen works too just thaw and drain off excess moisture
