Step-by-Step Instructions for Lemon Oatmeal Crumble Bars
  1. Preheat your oven to 350°F (177°C) and line an 8-inch square baking pan with parchment paper.
  2. In a mixing bowl, beat 7 tablespoons of softened unsalted butter with 3/4 cup of brown sugar until light and fluffy. Incorporate 1 teaspoon of vanilla extract, then gradually sift in 1 cup of all-purpose flour, 1 teaspoon of baking powder, 1/4 teaspoon of salt, and 1 cup of oats.
  3. Take half of the crumble mixture and press it evenly into the bottom of the prepared baking pan. Bake for 12 minutes until lightly golden.
  4. In a separate bowl, whisk together 1 can of sweetened condensed milk, 6 tablespoons of lemon juice, and 1 tablespoon of lemon zest until smooth.
  5. Pour the lemon filling over the cooled crust and sprinkle the remaining crumble mixture on top.
