How to Make It
- Prepare the Baking Dish:
- Line an eight by eight inch baking dish with parchment paper making sure the edges overhang for easy removal later press the paper into the corners fully so the crust sets evenly
- Mix and Press the Crust:
- Combine the graham cracker crumbs melted butter and granulated sugar in a mixing bowl use a fork to incorporate the butter thoroughly then press this mixture firmly and evenly into the bottom of your prepared pan pushing it down so you get a dense even layer
- Add the Fillings:
- Sprinkle the chopped rhubarb over the crust making sure every bite will get a little bit of tang then scatter on the white chocolate chips chopped nuts and shredded coconut in even layers do not press down
- Pour the Condensed Milk:
- Carefully pour the can of sweetened condensed milk over all the layers covering the toppings completely tilt the pan as needed so it runs into every corner and coats all the fillings
- Bake to Golden Perfection:
- Place the pan in the preheated oven on the middle rack bake for thirty to thirty five minutes until the bars are bubbling gently and look golden with a little browning at the edges rotate the pan if needed to avoid hot spots
- Cool and Slice:
- Remove from the oven and let cool completely at room temperature before lifting out by the parchment edges use a sharp knife for clean cuts wiping between slices for the tidiest bars

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

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

Several friends have told me they now grow rhubarb just for making magic bars and my neighbor once brought these to a block party where they disappeared before anyone snapped a photo
