- 2 cups rhubarb, chopped: The vibrant star of the filling, bringing a fresh tartness that wakes up your taste buds.
- 1 cup sugar: Sweetens the rhubarb gently, balancing its natural tang.
- 1 tablespoon cornstarch: Thickens the rhubarb filling to a luscious jam-like consistency.
- 1 tablespoon water: Helps the cornstarch activate and blend smoothly into the filling.
- 1 cup all-purpose flour: The base for the crumbly oat crust and topping, providing structure and softness.
- 1 cup old-fashioned rolled oats: Adds chewiness and wholesome texture to the bars.
- 1/2 cup brown sugar, packed: Infuses a rich caramel flavor that complements the oats beautifully.
- 1/2 teaspoon baking soda: Helps the crust rise just enough for a tender crumb.
- 1/2 teaspoon salt: Enhances all the flavors, balancing sweet and tart perfectly.
- 1/2 cup butter, softened: Gives the crust its buttery richness and binds everything together.
- 1 large egg: Binds the oat crust and topping into a tender yet sturdy base for the bars.
- 1/2 teaspoon vanilla extract: Provides a warm, aromatic undertone that ties all flavors together.
How to Make Amish Oatmeal Rhubarb Bars Recipe
Step 1: Prep Your Oven and Pan
Start by heating your oven to 350°F (175°C). Greasing your baking pan or lining it with parchment paper prevents sticking and makes removing those perfect bars a breeze. Using a 9×9-inch pan ensures the bars bake evenly and cut into satisfying square portions.
Step 2: Cook the Rhubarb Filling
In a small saucepan, combine the chopped rhubarb, sugar, cornstarch, and water. Cook it over medium heat, stirring every now and then until the mixture thickens and the rhubarb softens, usually about 5 to 7 minutes. This step transforms the rhubarb into a luscious filling that captures all that natural tartness with a smooth, jammy texture. Set it aside to cool before assembly.
Step 3: Prepare the Oat Crust and Topping
Grab a medium bowl and mix together the flour, oats, brown sugar, baking soda, and salt until evenly combined. Add the softened butter, egg, and vanilla extract, then stir until you get a crumbly dough that holds together when pressed. This mixture is what makes the crust sturdy yet tender, with just the right crumbly bite.
Step 4: Form the Crust
Press about two-thirds of your oat mixture into the bottom of your prepared pan. This layer forms the sturdy and flavorful base that supports the rhubarb filling beautifully. Make sure it’s packed evenly for consistent baking.
Step 5: Spread the Rhubarb Filling
Evenly spread the cooled rhubarb filling over the oat crust. Seeing that bright pink layer is what makes this Amish Oatmeal Rhubarb Bars Recipe so visually inviting and appetizing.
Step 6: Add the Crumbly Topping
Sprinkle the remaining oat mixture over the rhubarb filling to create a wonderfully textured topping. This final layer will bake to a golden brown with enticing crispy edges that perfectly contrast the soft filling.
Step 7: Bake to Perfection
Pop your assembled pan into the oven and bake for 35 to 40 minutes. You’re aiming for a bubbly filling and a golden brown oat topping. The aroma filling your kitchen at this point will have you counting down the minutes until it’s ready!
Step 8: Cool and Cut
Let the bars cool completely in the pan. This resting time allows the filling to set up perfectly, so your bars hold together when cut. Once cooled, slice into 16 squares and get ready to enjoy a piece of homemade comfort!
How to Serve Amish Oatmeal Rhubarb Bars Recipe
Garnishes
A light dusting of powdered sugar on top adds a pretty finishing touch without overpowering the lovely rhubarb flavor. For extra indulgence, try adding a dollop of whipped cream or a scoop of vanilla ice cream to each bar for a sweet and creamy contrast.
Side Dishes
These bars are fabulous on their own but pair beautifully with a cup of hot tea or coffee. For brunch, serve alongside fresh fruit or a yogurt parfait to complement the tartness with refreshing creaminess.
Creative Ways to Present
Looking to impress? Serve these bars on a rustic wooden board with seasonal berries scattered around. You can also cut them into bite-sized squares for a party platter or pack them individually for a picnic-ready treat that’s both portable and delicious.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Amish Oatmeal Rhubarb Bars in an airtight container at room temperature for up to two days or in the refrigerator up to five days. This helps retain their fresh texture and flavor without drying out.
Freezing
Freezing is a great option if you want to enjoy these bars later. Wrap them tightly in plastic wrap and foil, then place in a freezer-safe container. They’ll keep well for up to three months. When ready to eat, thaw in the refrigerator overnight.
Reheating
Warm your bars slightly in the oven at 300°F for about 10 minutes or microwave for about 20 seconds to bring back their fresh-from-the-oven softness and enhance the rhubarb aroma. Reheating will make them taste just as good as the first time!
FAQs
Can I substitute frozen rhubarb for fresh?
Yes, frozen rhubarb works well in this recipe. Just make sure to thaw and drain any excess liquid before cooking to avoid a watery filling.
What if I don’t have cornstarch?
You can substitute cornstarch with arrowroot powder or tapioca starch in equal amounts. These will also thicken the filling nicely without altering the flavor.
Are these bars gluten-free?
Not as written, since they use all-purpose flour and rolled oats, which may contain gluten. To make them gluten-free, use certified gluten-free oats and a gluten-free flour blend.
Can I use other fruits instead of rhubarb?
Definitely! Tart fruits like strawberries, raspberries, or a mix of berries work beautifully for a similar tangy-sweet effect.
How do I get the topping extra crunchy?
For a crunchier topping, sprinkle a little coarse sugar on top before baking or add a handful of chopped nuts like walnuts or pecans to the oat mixture.
Final Thoughts
This Amish Oatmeal Rhubarb Bars Recipe is a timeless treat that feels like a warm hug from the countryside. From the tangy-sweet rhubarb to the buttery oatmeal crumble, every bite is a joyous celebration of simple, honest ingredients.
