Rhubarb Shortbread Bars Recipes

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Mix 1 cup flour, butter, and confectioners' sugar together in a bowl; pack the mixture firmly into the bottom of a 9-inch square baking dish.
• Bake in preheated oven until the crust hardens slightly and is very fragrant, but not yet browned, about 15 minutes.
• Whisk brown sugar, eggs, white sugar, 1/4 cup flour, and salt together in a bowl until completely smooth; add rhubarb and stir to coat. Pour the rhubarb mixture over the crust.
• Bake in oven until the rhubarb mixture sets, about 40 minutes; cool at least 10 minutes before cutting into bars.

Steps:

• Crust: Combine all ingredients until crumbly.
• Pat half of mixture into 13x9" baking pan and bake for about 20 minutes before pouring filling on top.
• Filling: In saucepan combine rhubarb, sugar, cornstarch and water.
• Cook until clear.
• Blend in vanilla.
• Pour over baked crust.
• Sprinkle with remaining crumb mixture.
• Bake at 350° for 20 minutes.

Steps:

• Preheat oven to 350 degrees. Butter an 8-inch square baking pan. Line with parchment paper, leaving a 2-inch overhang on two sides. Butter and flour parchment and pan, tapping out excess flour.
• Make streusel: Whisk together butter, brown sugar, and salt. Add flour and mix with a fork until large crumbs form. Refrigerate until ready to use.
• Make cake: In a medium bowl, combine rhubarb, brown sugar, and 1/4 cup flour. In another medium bowl, whisk 3/4 cup flour, baking powder, and salt. In a large bowl, using an electric mixer, beat butter and confectioners' sugar until light and fluffy; beat in eggs, one at a time. With mixer on low, beat in vanilla, then flour mixture. Spread batter in prepared pan. Sprinkle with rhubarb and top with streusel.
• Bake cake until golden and a toothpick inserted in center comes out with moist crumbs attached, 45 to 50 minutes. Let cool completely in pan. Using paper overhang, lift cake from pan. Cut into 16 bars.

Steps:

• Heat oven to 325 degrees and line a 9-by-9-inch pan with parchment paper, leaving two edges long so they overhang the pan by at least 1 inch. (This is for lifting the bars out later.)
• In a food processor, pulse together flour, sugar and salt. Add butter and process until a crumbly dough forms. Press dough into the lined pan in an even layer. Don't clean out the food processor, you're going to need it.
• Bake crust until golden at the edges, 35 to 40 minutes, rotating halfway through. Transfer to a wire rack and raise oven temperature to 350 degrees.
• While the crust is baking, make the filling. In a medium saucepan, combine the rhubarb slices and 1 cup sugar. Cook, stirring frequently, over medium-low heat until rhubarb releases its juices. Raise heat and bring to a simmer. Keep simmering, stirring once in a while, until the rhubarb breaks down completely, about 15 to 20 minutes. Transfer the rhubarb and juices to the food processor, and let it sit with the cover off until it cools down a bit, about 15 minutes.
• Meanwhile, using a vegetable peeler, lay the very pink rhubarb stalk on its narrower side. From the edge of the stalk, peel a long strip from the stalk. Continue to peel strips from the stalk, flipping it around the other side to keep it even. (This makes it easier to peel, but don't worry too much about getting uniform strips.) Line up peeled strips and cut into 1 1/2-inch lengths. Some may curl up, and that's fine. You'll have about 1 cup strips.
• To the food processor, add the eggs, remaining 1/4 cup sugar, lemon juice, flour, zest and salt, and pulse until mixture is puréed. Pour into baked shortbread base, and carefully scatter the rhubarb strips on top. It should look a little like confetti. Bake until the filling is set and puffy, 20 to 30 minutes. Transfer to a wire rack to cool completely in the pan.
• Once cool, use a butter knife to cut at the edges of the crust to release them from the pan, then use the parchment "handles" to lift up and transfer the pastry to a cutting board. Cut into 1 3/4-inch squares. Dust with confectioners' sugar before serving.

Steps:

• For the bars: Preheat the oven to 350 degrees F with a rack in the middle.
• Grease and line a 9-inch square baking pan with parchment paper. Cut enough so there are wings hanging over the sides of the pan for when it's time to remove the bars!
• In a food processor, combine the flour, almond flour, granulated sugar and salt and pulse to combine. Add the butter, egg white and rosewater, if using. Pulse until the mixture clumps together into small to medium clumps of dough.
• Pour the dough out into the prepared pan and press evenly all around the bottom with a measuring cup or the back of a spatula until smooth.
• Bake until the crust is just set and the edges are light golden, 15 to 18 minutes. Remove to a rack to cool. Reduce the oven temperature to 325 degrees F.
• For the filling: Combine the rhubarb in a medium saucepan with water just to cover (about 1 1/2 cups water) and 1/4 cup granulated sugar. Scrape in the vanilla bean seeds and add the pod. Simmer until the rhubarb is falling apart, about 10 minutes. Cool, then strain and discard the solids. (See Cook's Note.)
• Add 1/4 cup of the reserved rhubarb juice to a small mixing bowl. Add the cornstarch. Use a small whisk or fork to combine until smooth and there are no cornstarch lumps. Add the rhubarb slurry to the saucepan with an additional 1/2 cup of the reserved rhubarb juice. (See Cook's Note for uses for any extra juice).
• Whisk in the eggs, yolks, salt, remaining 1 1/4 cups granulated sugar and 2 tablespoons lemon juice. Cook, whisking constantly, over medium heat until the mixture begins to simmer and thicken and bubbles pop to the surface, 7 to 10 minutes. Whisk in the zest, then the butter and coconut oil a little at a time. Whisk in just enough food coloring to make a salmon pink color, 2 to 3 drops.
• Pour the filling mixture over the cookie crust and bake until the edges are set, but the center is just a tiny bit jiggly, 25 to 30 minutes. Remove to a rack to cool completely.
• Once cooled, remove the bars from the pan. With a sharp knife, cut into 16 squares, wiping the blade after each cut. (You can also trim the edges for a cleaner look.) Dust with powdered sugar before serving.
• For longer storage, refrigerate between layers of parchment in a sealed container.

Steps:

• Make the jam: Combine rhubarb, sugar, and 1/2 cup water in a medium saucepan. Split vanilla bean, scrape the seeds into the pan, and toss in the pod. Bring to a simmer over low heat, cook, stirring often, until rhubarb softens and forms a soft mass, about 10 minutes. Remove and discard vanilla bean. Transfer to a shallow bowl and let cool. Can be made ahead and refrigerated in an airtight container, for up to one week. If refrigerated, return to room temperature before using. You may substitute 1 cup of your favorite jam or preserves for the homemade.
• Make the shortbread: In a medium bowl, whisk together flour, baking powder, and salt. In the bowl of an electric mixer fitted with the paddle attachment, beat butter on high speed until pale and fluffy. Add egg yolks and sugar, and beat until sugar is dissolved and the mixture is light. Reduce mixer speed to low, and add the dry ingredients, mixing only until the ingredients are incorporated.
• Turn the dough out onto a work surface and cut into two pieces. Shape each piece into a ball and wrap in plastic wrap. Place in freezer until firm, about 30 minutes. Can be made ahead and frozen for up to one month. Thaw in refrigerator overnight.
• Assemble and bake: Preheat oven to 350 degrees with rack in center. Remove one ball of dough from freezer and, using the large holes on a box grater, grate the dough into a 9-by-13-inch baking dish. Pat the dough gently just to get it into the corners (you don't want to press it down), and spread with the rhubarb jam. Grate the remaining dough over the jam, and press it lightly to distribute it evenly.
• Bake until golden brown, about 40 minutes. Dust with confectioners' sugar as soon as it is removed from oven. Cool on a wire rack.
• Cut the shortbread into bars when it is cool. You can cut whatever size bars please you, although as a rough guide, 3-inch squares, or rectangles 1 1/2 inches by 3 inches make nice servings. Store covered at room temperature for up to 2 days.
