Lemon Crumb Bars are a delightful dessert that combines a buttery crumb crust with a luscious lemon filling. These treat bars offer a perfect blend of brightness from fresh lemons and a satisfying crunch from crumbly oats, making them a go-to recipe for lemon lovers everywhere.
Ingredients for Lemon Crumb Bars
To create these delicious bars, you’ll need the following ingredients:
- 1 1/4 cups (177g) all-purpose flour
- 1 1/4 cups (110g) old-fashioned rolled oats
- 1/2 teaspoon (heaping) salt
- 1/2 teaspoon baking soda
- 1/2 cup (100g) granulated sugar
- 1/2 cup (100g) packed light-brown sugar
- 3/4 cup (170g) unsalted butter, melted
- 1 teaspoon vanilla extract
- 1 (14 oz) can sweetened condensed milk
- 1 tablespoon lemon zest
- 1/3 cup (80ml) fresh lemon juice
- 2 large egg yolks
- 1/2 teaspoon lemon extract
These ingredients come together beautifully, creating a treat that everyone will love!

Preparing the Base Crust
Whisk Flour and Oats
Begin by grabbing a medium mixing bowl. Whisk together the flour, rolled oats, salt, and baking soda until everything is well combined. The mixture should look fluffy and inviting.
Combine Sugars and Wet Ingredients
Next, stir in both sugars until no clumps remain. This step is crucial for a smooth texture. Then, mix your melted butter with the vanilla extract and pour it over the dry ingredients.
Mix Until Moistened
Using a spoon, stir the mixture until everything is evenly moistened. This process will take just a minute or two.
Press Into Baking Dish
Now, sprinkle half of the crumb mixture into a greased 8×8-inch baking dish. Gently press it into an even layer using your fingers or the back of a spoon.
Bake the Crust
Bake in a preheated oven at 350°F for 15 minutes. Once that time is up, remove it from the oven and set it aside. Keep that oven nice and warm; we’ll be using it again shortly!
Making the Lemon Filling

Whisk Lemon Filling Ingredients
In another mixing bowl, it’s time to whisk together the sweetened condensed milk, lemon zest, lemon juice, egg yolks, and lemon extract. Keep mixing until everything is thoroughly blended and smooth.
Pour Filling Over Crust
Carefully pour the lemon filling mixture over the baked crust in the baking dish. Make sure to spread it into an even layer—this will help ensure a perfect bite every time.
Finishing Touches
Add Remaining Crumb Mixture
Now, sprinkle the top evenly with the remaining crumb mixture. Be sure to distribute it well so that every part of the filling is covered.
Bake Until Golden
Return the dish to the preheated oven and bake for another 23 to 26 minutes. You’ll know it’s done when the topping is lightly golden. This may take a little watching, but it’s worth it!
Cool and Refrigerate
Once baked, remove from the oven and allow the bars to cool at room temperature. After they cool down, cover and refrigerate for 30 minutes to 1 hour. This chilling step really enhances the flavor.
Serving Suggestions
These Lemon Crumb Bars are best served chilled. For an elegant touch, consider dusting them with powdered sugar just before serving. You could also pair these delicious bars with a scoop of vanilla ice cream or enjoy them with a refreshing cup of iced tea.
Tips for Success
- Use fresh lemon juice for the best citrus flavor.
- Don’t skip chilling the bars; it really helps set the filling.
- If you’re feeling adventurous, try adding flavored extracts or a hint of ginger for a new twist.
Variations
To mix things up, you can substitute half of the lemon juice with lime juice for a zesty twist. Another fun idea is to add a handful of fresh blueberries into the lemon filling, giving it a burst of color and flavor. For an extra sweet touch, consider topping them with a lemon glaze.
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to a week. If you find yourself with extra bars, don’t worry! They can also be frozen for up to three months—just wrap them tightly and thaw them before serving.
Pairing Ideas
Pair these mouth-watering Lemon Crumb Bars with a refreshingly herbal tea. Alternatively, serve them alongside a light salad to create a delightful contrast to the sweetness of the bars.
