How to Make Lemon Oatmeal Crumble Bars

Step 1: Prepare the Crust

Start by preheating your oven to 350°F (175°C). In a large bowl, combine the rolled oats, flour, brown sugar, baking soda, and salt. Pour in the melted coconut oil and mix until crumbly. Press half of this mixture into the bottom of a greased baking dish. This forms the sturdy base that holds all those delicious layers together.

Step 2: Make the Lemon Filling

In another bowl, whisk together the fresh lemon juice, granulated sugar, cornstarch, vanilla extract, and water until smooth. Pour this lovely mixture over your pressed crust. This creamy layer is what makes our bars so delightful and tangy!

Step 3: Add the Topping

Sprinkle the remaining crumble mixture generously over the top of your lemon filling. This will create that satisfying crunch we all love in dessert bars!

Step 4: Bake to Perfection

Place your dish in the preheated oven and bake for about 38 minutes until golden brown on top. The aroma will fill your kitchen—trust me; it’s heavenly! Allow your bars to cool completely before slicing into squares.

Enjoy every bite of your homemade Lemon Oatmeal Crumble Bars! They’re sure to brighten any day.

Pro Tips for Making Lemon Oatmeal Crumble Bars

Making these Lemon Oatmeal Crumble Bars is a delightful experience, and with a few tips, you can ensure they turn out perfectly every time!

• Use fresh lemons: The zest and juice from fresh lemons provide a bright and vibrant flavor that bottled lemon juice simply can’t match. This will make your filling taste irresistibly fresh.

• Chill the crust before baking: Allowing the oatmeal crust to chill for about 10 minutes before baking helps it hold its shape better and results in a firmer base that won’t crumble apart when cut.

• Don’t skip the crumble topping: The crumbly topping is what makes these bars truly special! Ensuring you have generous amounts will give each bite a lovely texture contrast to the creamy lemon filling.

• Let them cool completely: After baking, allow your bars to cool at room temperature and then refrigerate before slicing. This will help them set nicely, making it easier to cut clean bars.

• Experiment with flavors: For a fun twist, consider adding some poppy seeds or blueberries into the lemon filling. These add-ins can elevate your bars even further, giving them a unique flair!
