What Ingredients Are in Lemon Crumb Bars?

This delicious dessert uses simple ingredients and makes the best lemon crumble bars!

  • All-purpose flour: The base of our crust and crumb topping.
  • Rolled oats: I really like the texture this gives to the crust.
  • Salt & Baking soda: These help with both taste and texture.
  • White and Brown sugar: For sweetness and some delicious molasses flavor.
  • Butter: Melted for a rich, smooth crust.
  • Vanilla extract: Use pure vanilla extract whenever possible.
  • Sweetened condensed milk: For a creamy, sweet lemon filling.
  • Lemon zest & Juice: Can’t go wrong with that zesty lemon flavor!
  • Egg yolks: Thicken the filling for a creamy texture.
  • Lemon extract: For an extra lemon punch.

Pro Tips:

  • Use fresh lemon juice and zest for the best lemon flavor.
  • Bottled lemon juice holds nothing on fresh lemons.
  • For a richer crust, opt for unsalted butter.

How to Store Leftover Lemon Crumb Bars

Leftovers of your lemon desserts should be stored in an airtight container in the refrigerator. 

They stay fresh and delicious for up to a week.

Be sure to always keep a lid on them so they don’t absorb any other flavors from the fridge. Yuck.

Also, if you leave them sitting out on the counter, they’ll go bad faster.

You can definitely use other juice to make these creamy lemon crumb squares! 

While lemon is classic, you can totally experiment.

Try lime juice or even a mix of citrus juices for a different twist.

Let me know what your favorite one is if you try lots of them!

Can Dogs Eat Lemon Crumb Bars?

No, dogs should not eat creamy lemon bars! 

The lemon and sugar content can be pretty harmful for them.

Actually, that goes for almost every human dessert you can think of.

If it doesn’t come packaged for dogs and it’s a treat? Then you probably shouldn’t feed it to your pup.

Are Lemon Crumb Bars Gluten-Free?

No, this recipe for classic lemon bars is not gluten-free. 

The all-purpose flour and oats both contain gluten actually. 

However, you can substitute with gluten-free alternatives to cater to dietary needs.

Things like gluten-free flour will usually work to substitute. They have 1-1 ratio flours available.

And with the oats, just buy the gluten free ones. Simple as that!
