Ingredients for Lemon Oatmeal Crumble Bars

  • 1 ½ cups rolled oats
  • 1 cup all-purpose flour
  • ¾ cup brown sugar
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • ½ cup unsalted butter, melted
  • 1 cup granulated sugar
  • 3 large eggs
  • 1 cup fresh lemon juice
  • Zest of 2 lemons
  • 2 tablespoons cornstarch

Directions

  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish. You can also line it with parchment paper for easier removal later.
  2. In a large mixing bowl, combine the rolled oats, flour, brown sugar, baking powder, and salt. Stir in the melted butter until well mixed and crumbly.
  3. Press two-thirds of the oat mixture into the bottom of the prepared dish, creating an even layer. Set the remaining oat mixture aside for later.
  4. In another bowl, whisk together the granulated sugar, eggs, fresh lemon juice, lemon zest, and cornstarch until smooth and well combined.
  5. Pour the lemon filling over the pressed oat layer in the baking dish, making sure it spreads evenly.
  6. Sprinkle the reserved oat mixture over the lemon filling, covering it evenly.
  7. Bake for 25 to 30 minutes or until the top becomes golden brown and the filling is set.
  8. Once baked, remove the dish from the oven and let it cool completely before slicing into bars. For best results, refrigerate for a couple of hours to help the bars hold their shape when cut.

Expert Tips for Lemon Oatmeal Crumble Bars

Achieving the perfect Lemon Oatmeal Crumble Bars comes down to a few expert tips. Firstly, ensure your lemons are fresh, as the zest and juice significantly impact the flavor. Roll the lemons on the counter before juicing to release more juice. When measuring, level off the flour and sugar using a straight edge to ensure accuracy. This helps avoid overly dense bars. Be cautious not to overmix the lemon filling; a gentle whisk is all that’s needed to combine the ingredients without introducing too much air. This prevents the filling from puffing up too much during baking. For the topping, you want the oat mixture to remain crumbly, so don’t overpack it when pressing into the pan. Lastly, patience is vital; allowing the bars to cool fully before cutting helps maintain their shape and allows the flavors to meld perfectly. These simple tips will elevate your bars and impress anyone lucky enough to taste them.

How to Store Lemon Oatmeal Crumble Bars

To keep your Lemon Oatmeal Crumble Bars fresh, store them in an airtight container. They can last at room temperature for up to three days, but placing them in the refrigerator can extend their shelf life to about a week. Ensure that the bars have completely cooled down before covering them to prevent condensation from forming, which can make them soggy. If you want to store them for an extended period, consider freezing them. Cut the bars into squares and wrap each piece in plastic wrap, then place them in a freezer-safe bag. They can last in the freezer for up to three months. When you’re ready to enjoy them, simply thaw them in the refrigerator or at room temperature. Reheating them slightly in the oven can revitalize their texture before serving.

Variations of Lemon Oatmeal Crumble Bars

There are many ways to switch up your Lemon Oatmeal Crumble Bars to keep things exciting! For a twist on the original flavor, try adding fresh berries like blueberries or raspberries to the lemon filling. This not only adds sweetness but also creates a beautiful marbled effect. If you prefer a nuttier taste, replace some of the all-purpose flour with almond flour or add chopped nuts like walnuts or almonds into the topping mixture. For a spicier kick, incorporate a dash of ginger or cinnamon into the oat topping. If you’re looking for a vegan alternative, use a flaxseed meal mixture as an egg substitute. Another delightful variation is to swap some of the lemon juice with lime juice for a tangy flavor. Consider adding shredded coconut for a tropical touch or white chocolate chips for a richer dessert. These variations provide a unique twist on the classic recipe while still maintaining its essence.
