You know its spring when the rhubarb arrives! Via Smitten Kitchen.
Yield: 16 small bars, as shown, or 8 large ones; recipe can be doubled and baked in a 9×13-inch baking pan, where they will come out a little thicker
- 1 cup (80 grams) rolled oats
- 3/4 cup (95 grams) plus up to 2 tablespoons (15 grams) extra all-purpose flour
- 1/2 cup (95 grams) light brown sugar
- Heaped 1/4 teaspoon table salt
- 6 tablespoons (85 grams) unsalted butter, melted
- 1 teaspoon cornstarch (optional, but helps firm up the filling)
- 1 tablespoon (15 ml) lemon juice
- 1 tablespoon (15 grams) granulated sugar, divided
- 1 cup (125 grams) small-diced rhubarb (from about 1 1/2 medium stalks)
- 1 cup (155 grams) small-diced strawberries
- Powdered sugar, for decoration, if desired
- Heat oven to 375 degrees F. For easy removal, line bottom and two sides of 8-by-8-inch square baking pan with parchment paper. No need to bother (and no greasing needed) if you plan to serve them right in the pan, as I did. [I did parchment paper and greased it.]
- Place oats, 3/4 cup flour, brown sugar and salt in bottom of baking pan and mix. [If you’re like me and put parchment paper in your pan, just mix all these ingredients in a bowl, then pour the butter over mixture in bowl, stir, remove 1/2 cup of mixture, press rest into bottom of pan.] Pour melted butter over, and stir until clumps form. If the clumps feel soft or look overly damp, add the remaining 2 tablespoons flour. Set aside 1/2 cup of the crumble mixture. Press the rest of the crumb mixture evenly in the bottom of the pan.
- Spread half the fruit over the crust. Sprinkle it evenly with cornstarch, then lemon juice, and 1/2 tablespoon of granulated sugar. Spread remaining fruit over this, and top with second 1/2 tablespoon sugar. Scatter reserved crumbs over fruit and bake bars for 30 to 40 minutes (firmer fruits will take longer), until fruit is bubbly and crisp portion is golden and smells toasty and amazing. [For me, it was more like 50-60 minutes to get the filling bubbly.]
- Let cool in pan; I do this in the fridge, where they become crisp once chilled (less so at room temperature). [Definitely do this step in fridge, it helps crisp up the bottom of the bars.] Cut into squares and sprinkle with powdered sugar before serving. Store leftovers in fridge.
