Strawberry Rhubarb Oat Bars

unnamedThe sweet-tart combo of strawberries and rhubarb is to die for, in my humble opinion. And since my rhubarb is threatening to take over the world this spring, I’m trying to find new and creative ways to use it up. When I saw a recipe on Better Homes & Garden’s website for bars using my favorite fruit duo, I said, “I’m in!” Then once I started perusing the recipe, I realized 1) the pan/batch was waaaaaaay too small to serve my family or co-workers, and 2) it looked strikingly similar to my blueberry breakfast bars previously posted! (Which DOES make a large enough batch to serve my family or co-workers…)

So I kinda combined my blueberry bar recipe with the BH&G recipe, and I think we’ve got us a winner here, people! Rhubarb is a little more finicky fruit than the berries, though. So it took a little trial and error to get it simmered the right length of time, and make sure the sugar ratio was on point. Now I’ve done all the heavy lifting for you. All you have to do is bake up a batch!

Makes 15 bars

2 cups old-fashioned rolled oats
1½ cups all-purpose flour*
¾ cup firmly-packed dark brown sugar
½ teaspoon baking soda
½ teaspoon cinnamon
¼ teaspoon salt
¾ cup butter, melted
3 cups chopped rhubarb
1 cup granulated sugar
¼ cup water
½ teaspoon ground ginger
3 cups sliced fresh strawberries
1 tablespoon cornstarch
1 tablespoon water

Preheat oven to 350° Fahrenheit. Grease an 11″x17″ pan with butter and set aside. In large bowl, combine oats, flour, brown sugar, baking soda, cinnamon, and salt. Stir to combine. Add melted butter and stir until all of oat mixture is combined with butter. Reserve 1 cup of the mixture and set aside. Press remaining oat mixture in bottom of prepared baking dish. Bake for 10 minutes. Remove from oven.

While crust is baking, combine rhubarb, granulated sugar, water, and ginger in large saucepan and heat on high. Once mixture starts to boil, turn to medium and simmer for 8-10 minutes, stirring occasionally. Rhubarb should start breaking up, and it should thicken up. Add strawberries and return heat to high. Once it starts to boil again, turn down to medium and simmer for 3-5 minutes. In small bowl or cup, combine cornstarch and water. Drizzle in to rhubarb and strawberries and stir until mixture thickens up a bit. Pour on top of baked crust and sprinkle with reserved oat crumbs. Bake for additional 30** minutes. Let cool completely before cutting into bars.

*NOTE: I’ve started using Costco’s Ultragrain flour, which is a non-GMO flour and may be tolerable to those who are sensitive to gluten. But it’s not for those with celiac disease!

**Next time I make these, I may try baking these 40 minutes once crust is topped with fruit. Rhubarb seems to require a longer baking time than berries, peaches, pears, etc. I was concerned about the top burning if I did them longer than 30 minutes, but I think they would have been fine.
