How to Make Lemon Oatmeal Crumble Bars

Step 1: Prepare Your Oven and Pan

Preheat your oven to 350°F (175°C). Greasing your baking pan ensures that the bars won’t stick when they’re done baking. A light coating of cooking spray or parchment paper works wonders here!

Step 2: Make the Crust and Topping Mixture

In a large bowl, combine rolled oats, flour, brown sugar, baking soda, and salt. Melt your butter (or coconut oil) and mix it into the dry ingredients until crumbly. This mixture forms both the crust and topping, so make sure it has a nice texture—think wet sand!

Step 3: Press into the Pan

Take about two-thirds of your mixture and press it firmly into the bottom of your prepared pan. This creates a sturdy base for our delicious lemon filling. Don’t forget to leave some crumbs aside for topping later!

Step 4: Prepare the Lemon Filling

In a saucepan over medium heat, whisk together fresh lemon juice, granulated sugar, cornstarch, lemon zest, and water. Stir continuously until it thickens—it should be smooth and glossy. This step is crucial because it brings out that amazing lemon flavor we love.

Step 5: Assemble Everything Together

Pour your luscious lemon filling over the pressed crust in the pan. Then sprinkle the reserved oat mixture evenly on top. This adds texture and balances out the creamy filling beautifully.

Step 6: Bake to Perfection

Bake in your preheated oven for about 38 minutes or until golden brown on top. Your kitchen will smell divine! Allow them to cool completely before cutting into squares; this helps maintain their shape.

And there you have it—delicious Lemon Oatmeal Crumble Bars that are sure to brighten anyone’s day! Enjoy every bite!

Pro Tips for Making Lemon Oatmeal Crumble Bars

These Lemon Oatmeal Crumble Bars are not only delicious but also easy to make with a few helpful tips!

• Use Fresh Lemons: Fresh lemon juice and zest give these bars an unbeatable zing. Bottled lemon juice lacks the vibrant flavor that fresh lemons provide, ensuring your bars are at their tangy best.

• Chill the Filling: If you allow the lemon filling to cool slightly before pouring it into the crust, it will set up better. This helps prevent the crumb topping from sinking into the filling, resulting in a beautiful layered effect.

• Don’t Overmix the Topping: When preparing your crumble topping, mix just until combined. Overmixing can lead to a tough texture instead of a light and crumbly topping that perfectly contrasts the creamy filling.

• Let Them Cool Completely: For clean cuts and to ensure your bars hold their shape, let them cool completely before slicing. This patience pays off in presentation!

• Experiment with Sweetness: If you prefer a sweeter bar, feel free to adjust the sugar levels in both the crust and filling. Just remember, the tartness of lemon balances sweetness beautifully!

How to Serve Lemon Oatmeal Crumble Bars

Presenting your Lemon Oatmeal Crumble Bars beautifully can turn an already lovely dessert into a showstopper! Here are some delightful serving suggestions.

Garnishes

• Powdered Sugar: A light dusting of powdered sugar adds a touch of elegance and sweetness without overwhelming the tangy flavor of the lemon.
• Fresh Berries: Top each bar with fresh raspberries or blueberries for a pop of color and an extra burst of fruitiness that complements the lemon beautifully.

Side Dishes

• Vanilla Coconut Yogurt: This creamy treat adds a refreshing contrast to the tangy bars while providing a luscious texture. It’s also dairy-free if you choose coconut yogurt!
• Mint-Infused Iced Tea: A chilled glass of mint-infused iced tea complements the citrus notes perfectly while keeping things refreshingly light.
• Fruit Salad: A simple mix of seasonal fruits can balance out the richness of the bars and offer a refreshing palate cleanser between bites.
• Lemon Sorbet: For those who can’t get enough lemon, pairing your bars with a scoop of zesty lemon sorbet is sure to elevate your dessert experience.
