These Lemon Crumb Bars come together with just a few pantry staples:
Dry Ingredients:
- 1 ¼ cups all-purpose flour
- 1 ¼ cups old-fashioned rolled oats
- ½ teaspoon salt
- ½ teaspoon baking soda
Sugars:
- ½ cup granulated sugar
- ½ cup packed light brown sugar
Wet Ingredients:

- 1 teaspoon vanilla extract
Filling:

👩🍳 How to Make Lemon Crumb Bars (Step-by-Step)
Here’s how to bring these sunny squares to life in your kitchen:
- Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment or spray with non-stick baking spray.
- In a large bowl, combine:
- Flour
- Oats
- Salt
- Baking soda
- Add both sugars and stir until well mixed.
- Pour in melted butter and vanilla extract. Stir until mixture becomes crumbly.
- Press half the mixture firmly into the bottom of the pan to form the base crust.
- Bake for 15 minutes or until lightly golden.
- Meanwhile, whisk together the lemon filling:
- Sweetened condensed milk
- Lemon zest
- Lemon juice
- Egg yolks
- Once the crust is baked, pour the filling over the hot base.
- Sprinkle remaining crumb mixture evenly over the top.
- Return to oven and bake for 20–22 minutes.
- Allow to cool completely, then refrigerate for at least 1 hour before slicing.
- For a special twist, dip the bottoms of frozen bars in melted white chocolate. Let set on wax paper.
💡 Expert Tips for Perfect Bars
- Chill before slicing for clean edges and to prevent oozing.
- Use fresh lemons—bottled juice lacks flavor and fragrance.
- Slightly underbake for a gooier center, or go golden for a firmer bite.
- Press crust firmly with a flat-bottomed glass or measuring cup.
- Add a tiny pinch of cinnamon to the topping for depth.
