Step‑by‑Step Instructions for Irresistible Apple Rhubarb Bars
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven warms up, gather your ingredients and equipment, making sure your baking pan is ready. This temperature will ensure a perfectly baked crust that is golden and crumbly for your Apple Rhubarb Bars.
Step 2: Prepare the Filling
In a medium saucepan, combine the tart rhubarb, 5.8 oz of sugar, grated apple, lemon juice, 4 tbsp of water, and a pinch of salt. Bring this mixture to a boil over medium heat, then reduce to a simmer. Cook for about 10 minutes, stirring occasionally, until the rhubarb softens. Continue simmering for 20-30 minutes until the filling thickens and has a jam-like consistency, then set aside to cool.
Step 3: Make the Dough
In a large mixing bowl, whisk together 11 oz of flour, 5 oz of sugar, and 1/4 tsp of salt. Next, add in the softened unsalted butter, the large egg, 1 tsp of vanilla extract, and 1/4 tsp of almond extract. Mix with a fork or your hands until the dough becomes crumbly and well combined, ensuring that it’s cohesive but not overworked.
Step 4: Divide the Dough
Once your dough is ready, divide it into two portions: reserve about three-quarters for the bottom crust and one-quarter for the topping. This division will maintain a balanced ratio of crust to filling in your Apple Rhubarb Bars, providing a delightful crunch on top.
Step 5: Prepare the Baking Pan
Line a 9-inch square baking pan with parchment paper, allowing some overhang for easy removal later. Press the larger portion of dough evenly into the bottom of the prepared pan, ensuring it covers the entire base. Aim for an even thickness to promote uniform baking and prevent sogginess.
Step 6: Add the Filling
Spread the cooled Apple Rhubarb filling evenly over the bottom crust. Ensure the filling reaches all corners of the pan for a balanced bar. The vibrant color and fragrant aromas will signal that your delicious dessert is coming together beautifully.
Step 7: Crumble the Topping
Take the reserved dough and crumble it over the filling, breaking it into small pieces. Sprinkle the sliced almonds on top to add a wonderful texture and nutty flavor to your Apple Rhubarb Bars. This crumbly topping will bake to a delightful golden brown.
Step 8: Bake to Perfection
Place the pan in the preheated oven and bake for about 40 minutes. Keep an eye on the bars, looking for a golden crust and bubbling filling around the edges. This visual cue indicates that your Apple Rhubarb Bars are fully baked and ready to cool.
Step 9: Cool and Cut
Once baked, remove the pan from the oven and let it cool in the pan for 15-20 minutes. This cooling period will help set the filling and allow for easier cutting. After that, use the parchment overhang to lift the bars out and slice them into squares for serving.

Make Ahead Options
These Irresistible Apple Rhubarb Bars are perfect for meal prep enthusiasts! You can prepare the filling (rhubarb, apples, and sugar) up to 3 days ahead and store it in an airtight container in the fridge. The crust can also be made in advance; simply combine the dry and wet ingredients, then refrigerate the dough for up to 24 hours. To maintain quality, ensure the filling is completely cooled before storing, as this prevents condensation and sogginess. When you’re ready to enjoy, just press the chilled dough into your pan, add the filling, crumble the topping, and bake as directed. You’ll have delicious, homemade bars with minimal effort!
Expert Tips for Apple Rhubarb Bars
Thick Filling: Ensure the filling is nicely thick before adding to the crust to prevent sogginess, achieving that perfectly biteable texture.
Softened Butter: Always use softened butter for the dough to create a smooth mixture; cold butter can lead to a crumbly, uneven crust in your Apple Rhubarb Bars.
Dough Chilling: Chill the portion of dough reserved for topping; this prevents tearing when you crumble it over the filling for a nice, even texture.
Cooling Time: Let the bars cool completely in the pan to ensure clean cuts. This patience pays off with beautifully shaped squares when served.
How to Store and Freeze Apple Rhubarb Bars
Room Temperature: Store the Apple Rhubarb Bars in an airtight container at room temperature for up to 2 days to maintain freshness.
Fridge: For extended freshness, keep them in the fridge for up to a week. Just remember to seal them well to avoid drying out.
Freezer: To freeze, wrap individual portions tightly in plastic wrap or aluminum foil, then place them in a freezer-safe container. They’ll keep well for up to 3 months.
Reheating: When ready to enjoy, thaw in the fridge overnight and reheat in a warm oven until just warmed through.
