Directions
Step-by-Step Instructions
-
Preheat the Oven: Preheat your oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) baking pan or line it with parchment paper, leaving an overhang around the edges for easy removal.
-
Prepare the Fruit Filling: In a mixing bowl, combine sliced strawberries, chopped rhubarb, granulated sugar, cornstarch, and lemon juice. Set aside to allow the fruit to release some juices.
-
Make the Oat Crust: In another bowl, whisk together flour, brown sugar, white sugar, cinnamon, and salt. Add the melted butter and rolled oats, mixing until crumbly.
-
Assemble the Bars: Press half of the oat mixture into the bottom of the prepared pan. Spread the fruit mixture evenly over it, then crumble the remaining oat mixture on top.
-
Bake: Place in the oven and bake for about 35-40 minutes, or until the top is golden brown and the fruit is bubbling.
-
Cool and Serve: Allow the bars to cool completely before cutting into squares and serving.

How to Store
Keeping Leftovers Fresh
To keep your strawberry rhubarb bars fresh, follow these storage tips:

Tips to Make
Helpful Cooking Tips
- Use Fresh Ingredients: The flavor of the bars is directly influenced by the quality of your fruit. Use ripe strawberries and fresh rhubarb for the best results.
- Adjust Sweetness: If you prefer a less sweet dessert, feel free to reduce the amount of granulated sugar in the fruit filling.
