• ¾ cup brown sugar
• ½ cup melted coconut oil
• ½ teaspoon baking soda
• ¼ teaspoon salt

How to Make Lemon Oatmeal Crumble Bars

Step 1: Preheat the Oven

Start by preheating your oven to 350°F (175°C). This step is crucial because it ensures that your bars will bake evenly and achieve that lovely golden color.

Step 2: Prepare the Crust

In a large bowl, combine rolled oats, flour, brown sugar, baking soda, and salt. Drizzle in melted coconut oil and mix until crumbly. Press half of this mixture firmly into the bottom of an ungreased 9×9-inch baking pan. This crust will provide a sturdy base for our luscious lemon filling.

Step 3: Make the Lemon Filling

In another bowl, whisk together fresh lemon juice, cornstarch, granulated sugar, and lemon zest until well combined. Pour this tangy mixture over the crust you’ve just pressed down. The brightness of the lemon will shine through beautifully!

Step 4: Add the Topping

Sprinkle the remaining oat mixture over the top of the lemon filling evenly. This will create that delightful crumble topping we all adore. It adds texture and absorbs some moisture from the filling as it bakes.

Step 5: Bake to Perfection

Place your pan in the preheated oven and bake for about 38 minutes or until the top is golden brown. The aroma wafting through your kitchen will be heavenly! Allow it to cool completely before slicing into bars—this helps everything set nicely.

Now you’re ready to enjoy these scrumptious Lemon Oatmeal Crumble Bars! Share them with friends or keep them all to yourself; I promise they won’t last long!

Pro Tips for Making Lemon Oatmeal Crumble Bars

Making the perfect Lemon Oatmeal Crumble Bars can be a delightful experience with just a few helpful tips!

• Use fresh lemons: Freshly squeezed lemon juice and zest provide the best flavor and brightness, making your bars taste incredibly fresh and vibrant.

• Chill the crust: Allowing the oatmeal crust to chill for about 10-15 minutes before baking helps it hold its shape better and creates a firmer texture that complements the creamy filling.

• Don’t overbake: Keep an eye on your bars during the last few minutes of baking. They should be set but still slightly soft in the center — they will firm up as they cool.

• Let them cool completely: Patience is key! Allow your bars to cool thoroughly at room temperature before cutting into them. This helps ensure clean cuts and prevents the filling from oozing out.

• Store properly: To keep your bars fresh, store them in an airtight container in the refrigerator. They can last up to a week, making them perfect for meal prep!

• Herbal tea: A cup of soothing herbal tea, such as chamomile or mint, enhances the experience and makes for a lovely afternoon snack or dessert pairing.
