How to Make Lemon Oatmeal Crumble Bars

Step 1: Prepare the Crust

Start by preheating your oven to 350°F (175°C). In a mixing bowl, combine rolled oats, flour, brown sugar, and salt. Then, cut in the cold coconut oil until the mixture resembles coarse crumbs. This buttery base holds everything together and gives your bars that delicious crumbly texture we love!

Step 2: Press the Mixture

Take about two-thirds of your crust mixture and press it firmly into an 8×8 inch baking dish. It’s important to pack it down well so your bars stay intact when sliced. Bake this beautiful crust in the preheated oven for about 10 minutes until it’s lightly golden.

Step 3: Make the Lemon Filling

While your crust bakes, whisk together fresh lemon juice, zest, sugar, cornstarch, and turmeric in another bowl until smooth. This creamy filling is where all that bright flavor comes from! Pour it over the baked crust once it’s done.

Step 4: Add the Crumble Topping

Now it’s time to sprinkle the remaining crumble mixture over your lemon filling. This step adds that irresistible crunch on top. Return everything to the oven and bake for an additional 28 minutes until golden brown.

Step 5: Cool and Serve

Once out of the oven, let your Lemon Oatmeal Crumble Bars cool completely before slicing them into squares. Patience is key here—allowing them to set will make cutting much easier! Enjoy these tasty treats with family or friends; they’re sure to brighten anyone’s day!

Pro Tips for Making Lemon Oatmeal Crumble Bars

Making these delightful lemon oatmeal crumble bars can be a breeze with a few handy tips. Here are some suggestions to ensure your bars turn out perfectly every time!

• Use fresh lemons: Freshly squeezed lemon juice enhances the flavor of the filling, making it more vibrant and tangy compared to bottled juice.
• Chill your butter: For a flakier crust, make sure your butter is cold when mixing it into the oatmeal and flour. This helps create that lovely crumbly texture in the base.
• Don’t skip the chilling time: Allowing the bars to cool completely before cutting helps them hold their shape better. This patience pays off in presentation!
• Adjust sweetness to taste: If you prefer your dessert less sweet, feel free to reduce the sugar in the filling. The tartness of the lemon will still shine through beautifully!
• Experiment with toppings: Try adding nuts or seeds to the crumble topping for an extra crunch. Almonds or sunflower seeds can complement the flavors nicely.
