Ingredient List

Here’s the Ingredient List for Amish Oatmeal Rhubarb Bars:

For the Oatmeal Crust and Topping:
  • 2 cups rolled oats
  • 1 cup all-purpose flour
  • 1 cup brown sugar (packed)
  • 1/2 cup butter, softened
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
For the Rhubarb Filling:
  • 3 cups rhubarb, chopped into 1-inch pieces
  • 1 cup granulated sugar
  • 1 tablespoon cornstarch
  • 1/2 cup water

Step-by-Step Instructions

Here’s the step-by-step guide to making Amish Oatmeal Rhubarb Bars:

1. Preheat the Oven and Prepare the Pan:

  • Preheat your oven to 350°F (175°C).
  • Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.

2. Prepare the Oatmeal Crust and Topping:

  • In a large mixing bowl, combine the rolled oats, all-purpose flour, brown sugar, baking soda, and salt.
  • Add the butter (softened) and use a pastry cutter or your fingers to mix it into the dry ingredients until the mixture becomes crumbly, with pea-sized pieces of butter still visible.
  • Press about two-thirds of this oatmeal mixture into the bottom of the prepared baking dish, creating a firm and even crust. Set the remaining one-third aside for the topping.

3. Make the Rhubarb Filling:

  • In a medium saucepan, combine the chopped rhubarb, granulated sugar, and water.
  • Bring the mixture to a boil over medium heat, stirring occasionally.
  • Once it starts boiling, reduce the heat and simmer for about 5-7 minutes, stirring occasionally, until the rhubarb softens and releases its juice.
  • In a small bowl, mix the cornstarch with 2 tablespoons of water to form a slurry.
  • Gradually add the cornstarch mixture to the simmering rhubarb, stirring constantly. Continue to cook for another 2-3 minutes, until the filling thickens to a spreadable consistency. Remove from heat and let it cool slightly.

4. Assemble the Bars:

  • Spread the rhubarb filling evenly over the oatmeal crust in the baking dish.
  • Sprinkle the remaining one-third of the oatmeal mixture evenly over the rhubarb filling, creating a crumbly topping.

5. Bake the Bars:

  • Place the baking dish in the preheated oven and bake for about 35-40 minutes, or until the top is golden brown and the rhubarb filling is bubbly.
  • Remove from the oven and let the bars cool completely in the pan. This will help the filling set.

6. Cut and Serve:

  • Once the bars have cooled, cut them into squares or bars.
  • Serve as is, or with a dollop of whipped cream or vanilla ice cream for an extra indulgence.

1. Whipped Cream or Fresh Cream

  • How: Serve a dollop on top of the bars for an indulgent touch, or even a splash of heavy cream on the side.

  • How: Serve with a cup of freshly brewed coffee or an iced coffee if you prefer a cold beverage.

5. Fruit Compote or Fresh Berries

  • Why: A light fruit compote (like strawberry or raspberry) or fresh berries (like strawberries, blueberries, or blackberries) will complement the tartness of the rhubarb while adding a burst of freshness.
  • How: Spoon a bit of fruit compote on the side or top the bars with fresh berries.

6. Greek Yogurt or Vanilla Yogurt

  • Why: The tang of yogurt can balance the sweetness of the rhubarb while adding a creamy texture. Greek yogurt, in particular, has a nice thickness and tang that pairs well.
  • How: Serve a spoonful of yogurt alongside the bars, or swirl it over the top for a nice contrast.

7. Lemonade or Iced Tea

  • Why: A refreshing, slightly tart beverage like lemonade or iced tea will provide a perfect balance to the sweet and tangy flavors of the bars.

  • How: Sprinkle chopped nuts on top of the bars or serve them on the side for a bit of added crunch.

Top Tips for Perfecting Amish Oatmeal Rhubarb Bars Recipe

  4. Taste the Filling – Adjust sugar levels in the rhubarb filling to balance tartness to your liking.
  5. Chill the Bars for Clean Slices – Refrigerating for an hour after baking helps the bars firm up, making them easier to cut.

Ingredient Substitutions

If you’re looking to make substitutions for the ingredients in Amish Oatmeal Rhubarb Bars, here are some ideas that maintain flavor and texture:

For the Oatmeal Crust and Topping:

  1. Butter:
    • Substitute: Coconut oil, vegetable oil, or vegan butter.
    • Why: For a dairy-free version or a slightly different flavor profile.
  2. Brown Sugar:
    • Substitute: Coconut sugar, maple syrup, or honey.
    • Why: If you’re looking for a natural sweetener or trying to reduce refined sugars.
  3. Rolled Oats:
    • Substitute: Quick oats or steel-cut oats.
    • Why: Quick oats will work fine for the crust, though they will create a slightly finer texture. Steel-cut oats will result in a chewier texture and may need more liquid.
  4. All-Purpose Flour:
    • Substitute: Whole wheat flour or almond flour (for gluten-free).
    • Why: Whole wheat flour will add more depth of flavor, while almond flour is perfect for gluten-free baking.
  5. Baking Soda:
    • Substitute: Baking powder (use 1 teaspoon if substituting for baking soda).
    • Why: If you don’t have baking soda, baking powder works to help with the rise and texture.
  6. Salt:
    • Substitute: Sea salt or kosher salt.
    • Why: Different salts can alter flavor subtly, but the role of salt remains the same.

For the Rhubarb Filling:

  1. Granulated Sugar:
    • Substitute: Stevia, monk fruit sweetener, or maple syrup.
    • Why: For a low-carb or alternative sweetener option.
  2. Cornstarch:
    • Substitute: Arrowroot powder, potato starch, or all-purpose flour.
    • Why: For thickening the filling without using cornstarch, these options provide similar results.
  3. Water:
    • Substitute: Orange juice, apple juice, or even rhubarb juice (if available).
    • Why: A different liquid can add a bit of extra flavor to the rhubarb filling.

F or the Bars’ Flavor and Texture:

  1. Cinnamon or Nutmeg:
    • Substitute: Pumpkin spice, allspice, or ground ginger.
    • Why: These spices add warm, cozy flavors that complement rhubarb and oats.
  2. Vanilla Extract:
    • Substitute: Almond extract or maple extract.
    • Why: For a slightly different flavor twist without losing sweetness.

Timing Adjustments

Here are some timing adjustments to consider when making Amish Oatmeal Rhubarb Bars:

1. Baking Time Adjustments:

  • If Using a Smaller or Larger Pan:
    • Smaller pan: Bars will be thicker, so you may need to increase the baking time by 5-10 minutes.
    • Larger pan: Bars will be thinner, so reduce baking time by about 5-10 minutes.
  • Tip: Start checking for doneness around the lower end of the suggested time (35 minutes) and increase if necessary. The top should be golden, and the filling should be bubbly.

2. Cool Down Time:

  • Cooling the Bars:
    • It’s best to let the bars cool for at least 1-2 hours at room temperature before cutting, to allow the filling to set and become easier to slice. If in a rush, refrigerating them for 30-60 minutes can speed up this process.
  • Tip: Don’t cut the bars while they’re warm—this can make the filling runny. Let them cool completely or chill for clean slices.

3. Chill for Firmness:

  • If You Want a Firmer Texture:
    • After baking, chill the bars in the fridge for 1 hour to help set the rhubarb filling. This will make the bars easier to cut and will help the filling firm up.

4. Adjusting the Rhubarb Cooking Time:

  • If Rhubarb is Overripe:
    • Overripe rhubarb might release more liquid than expected, so reduce the cooking time by 2-3 minutes.
  • Tip: Keep an eye on the consistency of the rhubarb filling. If it looks too watery, continue to cook it down until it thickens before transferring it to the crust.

5. Crust and Topping Prep:

  • If Using Cold Butter:
    • Cold butter will take a little longer to work into the dry ingredients, so factor in an extra 5 minutes for prep time.
  • Tip: If you’re short on time, consider cutting the butter into small cubes before mixing, to speed up the process.

Common Mistakes to Avoid Amish Oatmeal Rhubarb Bars Recipe

Here are some common mistakes to avoid when making Amish Oatmeal Rhubarb Bars:

1. Not Using Enough Rhubarb

  • Mistake: Skimping on the rhubarb can result in a filling that’s too thin and lacking that tangy flavor.
  • Solution: Use at least 3 cups of chopped rhubarb for a balanced filling. If you’re using frozen rhubarb, make sure to drain the excess liquid.

2. Overmixing the Oatmeal Crust

  • Mistake: Overmixing the oatmeal mixture will make the crust dense and tough rather than light and crumbly.
  • Solution: Mix just until the butter is incorporated and the mixture forms a crumbly texture. Use your hands or a pastry cutter to avoid overworking it.

3. Not Letting the Bars Cool Enough

  • Mistake: Cutting the bars while they’re still warm can lead to runny filling and messy slices.
  • Solution: Let the bars cool completely at room temperature for 1-2 hours, or refrigerate them for at least 30-60 minutes to allow the filling to set properly.

4. Underbaking the Bars

  • Mistake: Not baking long enough can leave the crust underdone or the filling too runny.
  • Solution: Ensure the bars are baked until the top is golden brown and the filling is bubbling. Start checking around 35 minutes, and adjust based on the thickness of the bars.

5. Ignoring the Thickness of the Rhubarb Filling

  • Mistake: If the rhubarb filling is too runny, it can make the bars soggy or difficult to cut.
  • Solution: Use cornstarch to thicken the filling, and make sure to cook it down to a thick, spreadable consistency before layering it over the crust. If you’re using frozen rhubarb, reduce the cooking time to avoid excessive moisture.

6. Not Using Cold Butter

  • Mistake: Using soft butter can result in a less crumbly crust and topping.
  • Solution: Use cold butter straight from the fridge. Cut it into small cubes before incorporating it into the dry ingredients for the best crumbly texture.

7. Using Too Much Sweetener in the Filling

  • Mistake: Adding too much sugar can overpower the rhubarb’s tartness, making the bars overly sweet.
  • Solution: Taste the filling as it cooks and adjust the sugar to your preference. Start with 1 cup of granulated sugar and adjust from there, based on the sweetness of your rhubarb.

8. Not Checking for Doneness

  • Mistake: Assuming the bars are done just because the top looks golden, without checking the center.
  • Solution: Test the bars by gently pressing the top. If it feels firm and the filling is bubbling, they’re ready. A toothpick test won’t work well due to the rhubarb filling.

9. Using the Wrong Pan Size

  • Mistake: Using a pan that’s too small or too large can affect the baking time and texture of the bars.
  • Solution: Stick to a 9×13-inch pan for the best results. If using a smaller pan, increase the baking time; if using a larger pan, reduce the baking time.

10. Not Letting the Filling Thicken Enough

  • Mistake: If you don’t cook the rhubarb enough or don’t use cornstarch, the filling can be runny and may leak into the crust.
  • Solution: Cook the filling until it’s thick enough to hold its shape, and use the cornstarch slurry to help achieve a thicker consistency.
