Description

These Lemon Crumb Bars are like sunshine in dessert form! A buttery oat crust holds a tangy, creamy lemon filling, topped with a golden crumble that bakes up crisp and irresistible. They’re easy, bright, and bursting with citrus flavor—perfect for spring gatherings, picnics, or just when you need a sweet pick-me-up!


Ingredients

Scale

Crust & Crumble Topping:
1 ¼ cups all-purpose flour

1 ¼ cups old-fashioned rolled oats

½ teaspoon salt

½ teaspoon baking soda

½ cup granulated sugar

½ cup packed light brown sugar

¾ cup unsalted butter, melted

1 teaspoon vanilla extract

Lemon Filling:
1 (14 oz) can sweetened condensed milk

2 tablespoons finely grated lemon zest

½ cup fresh lemon juice

2 large egg yolks


Instructions

  • Preheat oven to 350°F (175°C). Grease an 8×8-inch baking pan with baking spray.

  • In a large bowl, combine flour, oats, salt, and baking soda. Stir in both sugars.

  • Add melted butter and vanilla extract; mix until crumbly.

  • Press half the mixture into the pan. Bake for 15 minutes.

  • In another bowl, whisk together sweetened condensed milk, lemon zest, lemon juice, and egg yolks.

  • Pour filling over the warm crust. Crumble the remaining oat mixture on top.

  • Bake an additional 20–22 minutes, until golden.

  • Cool completely, then refrigerate until firm. For cleaner slices, chill well or freeze briefly before cutting.

  • Optional: Dip frozen bars in melted white chocolate and refrigerate until set.

Notes

  • Fresh lemon juice is best—its brightness really makes these bars pop.

  • For extra indulgence, don’t skip the white chocolate dip!

  • These bars freeze beautifully and taste amazing straight from the freezer on warm days.

  • You can swap lemon with lime or orange for a fun twist!
