Ingredients You’ll Need

When making these delicious bars, start by selecting the right ingredients:

All-Purpose Flour
You typically use 1 cup to give structure to the crust.
Prepare by measuring it out using the spoon and level method for accuracy.
If you’re looking for an alternative, consider using whole wheat flour, though it may alter texture slightly.
Tip: Sift the flour if it’s clumpy for a smoother crust.

Old-Fashioned Oats
1 cup of oats adds a hearty texture and a wholesome flavor to the crumb topping.
No need to prepare; just add them directly.
If you’re looking for an alternative, quick oats can work, but the texture will be softer.
Warning: Avoid instant oats, as they do not hold up well in baking.

Salt
A pinch of 1/4 teaspoon helps to enhance the flavors of the bars.
No prep necessary—just measure and add.
If you prefer, you can use sea salt or omit it for a low-sodium option.

Baking Soda
3/4 teaspoon helps the crust rise slightly for a fluffy texture.
Measure and mix with dry ingredients before adding to the recipe.
No alternatives needed here—it’s essential for texture!

Unsalted Butter
10 tablespoons of melted butter gives richness and moisture to the crust.
Melt it gently in the microwave before adding.
If you’re looking for an alternative, coconut oil can be used, but it may change flavor slightly.

Light Brown Sugar
Using 1/2 cup packed gives a deep, caramel-like sweetness to the crumb.
Just pack it into your measuring cup before using.
If you prefer, you can substitute it with granulated sugar, though it will be less rich.

Pure Vanilla Extract
1 teaspoon adds wonderful aroma and enhances all other flavors.
No special preparation—just measure it out.
If you want an alternative, almond extract works nicely, adding its own unique flavor.

Sweetened Condensed Milk
1 can (14 oz) is crucial for that creamy, lemony filling.
Simply open the can and pour it in.
No good substitute exists, so be sure to use this ingredient.

Sour Cream (or Plain Yogurt)
2 tablespoons contribute to the creaminess of the filling.
Spoon it in directly for easy mixing.
If you’re looking for an alternative, Greek yogurt works similarly.

Egg Yolk
1 large egg yolk helps bind the filling together and give it richness.
Separate the yolk from the white carefully.
If you’re looking for an alternative, you can use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water).

Freshly Squeezed Lemon Juice
1/4 cup provides the essential tartness to balance sweetness.
Juice fresh lemons for the best flavor.
If you’re looking for an alternative, bottled lemon juice can be used, though fresh is preferred.

Finely Grated Lemon Zest
1 tablespoon adds another layer of lemony aroma and taste.
Use a microplane or grater to get fine zest.
No alternatives exist, as zest is integral for flavor.

Step-by-Step Instructions

Making these bars is a breeze! You can whip them up in just a few steps in one pan.

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures a perfect bake for your bars.

Step 2: Prepare the Pan
Grease an 8-inch square baking dish lightly with butter or cooking spray. This helps your bars come out easily and keeps the bottom from sticking.

Step 3: Mix the Crust
In a large bowl, combine flour, oats, salt, baking soda, and brown sugar. Stir well. Then add melted butter and vanilla extract. Mix until crumbly, with some larger chunks. This texture will create a great crust!

Step 4: Steady the Base
Press about two-thirds of the crumb mixture evenly into the bottom of the prepared pan. Bake for 12-15 minutes until lightly golden. This initial baking helps the crust set and prevents sogginess.

Step 5: Mix the Filling
While the crust is baking, whisk together the sweetened condensed milk, sour cream, egg yolk, lemon juice, and lemon zest in another bowl until well combined. This mixture should be creamy and smooth.

Step 6: Bake the Filling
Pour the lemon filling over the pre-baked crust evenly. Then sprinkle the remaining crumb mixture on top. Return the pan to the oven and bake for an additional 25-30 minutes, or until the center is set. You’ll know it’s ready when a toothpick comes out clean.

Step 7: Cool & Cut
Remove the bars from the oven and let them cool completely in the pan. Once cooled, cut them into squares. This helps the bars firm up and makes cutting easier.

How to Serve

  1. Presentation: Arrange the bars on a pretty platter and dust with powdered sugar for an elegant touch.
  2. Accompaniments: Serve with whipped cream or fresh berries for extra flavor.
  3. Portions: Cut into small squares, as they are quite rich and satisfying.
  4. Beverage pairing: Enjoy with iced tea or lemonade to complement the lemony flavor.

These serving suggestions will make your Lemon Crumb Bars even more delightful!

  3. Chocolate Lemon Crumb Bars: Drizzle melted chocolate over the top once cooled for a chocolatey treat.

Freezing and Storage

  • Storage: Keep the bars in an airtight container in the refrigerator for up to a week.
  • Freezing: You can freeze the bars for up to 3 months. Wrap them well in plastic wrap and then foil for the best protection.
