Ingredients and Preparation

For these Oatmeal Lemon Crumble Bars, you will need:

• Oats
• Butter
• Brown sugar
• Lemon zest
• Lemon juice
• Eggs
• Vanilla extract
• All-purpose flour
• Baking soda
• Salt
• Powdered sugar
• Heavy cream

Each of these ingredients plays a vital role in creating the perfect bar:

• Oats: These form the base and give the dessert a hearty texture, providing a satisfying chew that complements the creamy top. They also add a mild nutty flavor.
• Butter: The butter adds richness and moisture to the oat base, helping bind the dry ingredients together and creating a soft, tender crust.
• Brown sugar: Adds a deep, molasses-like sweetness to balance the tartness of the lemon and helps to caramelize the oat crust.
• Lemon zest & Lemon juice: These two ingredients provide the signature citrusy flavor. The zest gives a fragrant, intense lemon flavor, while the juice adds acidity to cut through the richness of the bars.
• Eggs: Eggs help bind the lemon filling together, creating a smooth and creamy texture.
• Vanilla extract: Vanilla enhances the overall flavor and balances out the tanginess of the lemon.
• Flour: Flour is needed for structure, both in the crust and the filling, giving the bars their sturdiness.
• Baking soda & Salt: These leavening agents ensure that the crust rises properly while balancing out the sweetness.
• Powdered sugar: Used in the filling, powdered sugar creates a smooth and velvety texture without being overly sweet.
• Heavy cream: Adds richness and helps create a silky lemon filling that contrasts beautifully with the dense oat crust.

Substitution Options:

• For a dairy-free version, swap the butter for coconut oil or a plant-based butter and use non-dairy cream.
• If you’re looking for a gluten-free option, use certified gluten-free oats and a gluten-free flour blend.
• If you’re not a fan of lemon, you can experiment with other citrus fruits like orange or lime for a different flavor twist.

Step-by-Step Instructions

Step 1: Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper for easy removal later, and lightly grease the edges to prevent sticking.

Step 2: In a mixing bowl, combine your oats, flour, brown sugar, and baking soda. Add melted butter and mix until the dough resembles a crumbly texture. Reserve 1 cup of this mixture to use later as a topping.

Step 3: Press the remaining oat mixture firmly into the bottom of your prepared baking pan. Use the back of a spoon to smooth it out evenly, making sure it’s well-packed. This will form the oat base.

Step 4: Bake the base in the preheated oven for 10-12 minutes or until lightly golden brown around the edges. While it’s baking, you can prepare the lemon filling.

Step 5: In a separate bowl, whisk together eggs, lemon juice, lemon zest, vanilla extract, and powdered sugar until smooth. Then, add the heavy cream and flour, mixing until everything is fully combined and you have a creamy filling.

Step 6: Once the oat base is done baking, remove it from the oven and pour the lemon mixture evenly over the warm crust.

Step 7: Sprinkle the reserved oat mixture over the top of the lemon filling. Don’t worry if it’s not perfectly even—the crumble topping will create a rustic look.

Step 8: Return the pan to the oven and bake for an additional 20-25 minutes or until the top is golden and the filling is set. The filling should jiggle slightly when you tap the pan.

Step 9: Allow the bars to cool completely in the pan before cutting into squares. This will help the filling set and make it easier to slice.

Step 10: Once cooled, dust the bars with a little extra powdered sugar for a finishing touch.

Beginner Tips and Notes

• How to tell when the bars are done: The filling should look firm and not liquid when tapped. If it’s still runny, return it to the oven for a few extra minutes.
• How to avoid over-baking the oat crust: Keep an eye on the crust in the first phase of baking. If it starts turning too dark, lower the temperature slightly and continue baking until it’s golden.
• Chill before cutting: For clean cuts, refrigerate the bars for about 30 minutes before slicing.

These tips will help you create perfect oatmeal lemon crème bars every time. With just a few simple techniques, even beginners can master this recipe and impress friends and family.

Serving Suggestions

These Oatmeal Lemon Crumble Bars are delicious on their own, but they can be paired with a variety of sides or sauces to elevate the experience:
