Method
 

Step-by-Step Instructions
  1. Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with aluminum foil or parchment paper.
  2. Whisk the dry ingredients: In a medium bowl, whisk together flour, oats, salt, and baking soda.
  3. Mix the wet ingredients: In a larger bowl, mix melted butter, brown sugar, and vanilla extract until smooth.
  4. Combine dry and wet mixtures, stirring gently until a crumbly dough forms.
  5. Set aside about 3/4 cup of the dough and press the remaining mixture evenly into the bottom of the prepared pan.
  6. Bake the crust for about 10 minutes, until light golden brown.
  7. Prepare the lemon filling: Whisk together sweetened condensed milk, sour cream, egg yolk, lemon juice, and zest until smooth.
  8. Pour the lemon filling evenly over the warm crust.
  9. Sprinkle the reserved crumb topping over the filling, covering it completely.
  10. Bake for an additional 17 to 20 minutes, until topping is golden brown and filling is set but slightly jiggly.
  11. Cool the lemon crumb bars completely on a wire rack, then slice into squares for serving.
