Ingredients

Crumb Topping
  • ½ cup unsalted butter, gently melted and then cooled a bit (plus a bit more room-temperature butter to grease the pan)
  • ¾ cup packed light brown sugar
  • ¼ teaspoon Morton kosher salt
  • 1¼ cup all-purpose flour
Bars
  • ½ pound chopped (½" pieces) fresh rhubarb
  • ½ pound fresh strawberries, hulled and sliced ¼" thick
  • 2 tablespoons packed light brown sugar
  • 1½ cups all-purpose flour, divided
  • ¾ teaspoon baking powder
  • ½ teaspoon Morton kosher salt
  • ¾ cup unsalted butter, at room temperature
  • 1½ cups Powdered sugar, plus a bit more for dusting over the finished bars
  • 3 large eggs
  • 2 teaspoons pure vanilla extract

Instructions

    Cup of Yum
  1. Preheat oven to 350°F. Lightly grease a 9'' square baking pan with butter, then line with a parchment paper sling, leaving an overhang on 2 sides. Butter and flour the parchment paper and pan, tapping out the excess flour. Set aside.
Crumb Topping
    Cup of Yum
  1. Whisk together butter, brown sugar, and salt. Add flour and cut with a rigid pastry cutter or fork until large crumbs form. Refrigerate until ready to use.
Bars
  1. In a medium bowl, combine rhubarb, strawberries, brown sugar, and ¼ cup of the flour.
  2. In another medium bowl, whisk the remaining 1¼ cups of flour, baking powder, and salt.
  3. In a large bowl, using an electric mixer, beat butter and powdered sugar until light and fluffy. Then beat in the eggs, one at a time. With mixer on low, beat in vanilla, then the flour mixture.
  4. Spread batter evenly into prepared pan. Top with rhubarb and strawberry mixture, then top with streusel crumb topping. If you like to have some of the pretty red of the rhubarb and strawberries show on top (I do!), poke a few pieces up through the streusel.
  5. Bake 50-55 minutes, or until topping is golden and a toothpick inserted in the center comes out with just a bit of moist crumbs attached. If crumb topping is browning more than you like and the cake is not yet fully baked, lay a piece of foil loosely over the pan while it continues to bake.
  6. Remove pan from oven. Let bars cool completely in pan. Run a knife around the edge of the pan and, using the parchment paper overhang, lift cake from pan. Cut into bars; dust with powdered sugar if desired. Serve as is, or with dollops of fresh whipped cream.
