Instructions
- Preheat oven to 350F (175C); position rack in center for even baking.
- Grease a 9-inch square dish; line with parchment, overhanging sides for easy removal.
- In food processor, pulse all-purpose flour, almond flour, 1/2 cup sugar, and salt. Add butter, egg white, and rosewater; process until dough clumps form.
- Press dough evenly into pan base using a measuring cup bottom for a smooth crust.
- Bake 15-18 minutes until set and edges golden. Cool on rack; reduce oven to 325F (163C).
- Simmer rhubarb, 1/4 cup sugar, vanilla seeds/pod, and water to cover (~1 1/2 cups) for 10 minutes until broken down. Cool, strain, discard solids.
- Mix 1/4 cup rhubarb liquid with cornstarch; return to pan with 1/2 cup more liquid.
- Whisk in eggs, yolks, salt, remaining 1 1/4 cups sugar, lemon juice. Cook over medium heat, whisking until thickened and bubbling (7-10 minutes). Stir in zest, then butter and coconut oil gradually. Tint drop-by-drop to salmon-pink.
- Pour over crust; bake 25-30 minutes until edges firm, center jiggles slightly. Cool fully.
- Lift out with parchment; cut into 16 neat squares (wipe knife between cuts). Dust with powdered sugar.
- Store layered with parchment in airtight container; refrigerate for freshness.
Pro Tip: Dry the vanilla pod for infused sugar or coffee. Use leftover rhubarb syrup in iced tea or cocktails for a tangy twist. These vibrant pink rhubarb rose bars burst with tart-sweet flavorperfect for impressing at your next gathering!
