Ingredients You'll Need

• ¾ teaspoon baking soda
• 10 tablespoons unsalted butter, melted
• ½ cup light brown sugar, packed
• 1 teaspoon pure vanilla extract

• 1 can sweetened condensed milk (14 oz)
• 2 tablespoons sour cream or plain yogurt
• 1 large egg yolk
• ¼ cup freshly squeezed lemon juice
• 1 tablespoon finely grated lemon zest

Step-by-Step Instructions

Preparing the Ingredients

1. Preheat your oven to 350°F (175°C). Grease an 8x8 inch baking pan with butter or line it with parchment paper for easy removal.
2. Gather all your ingredients to ensure you have everything ready to go.

Mixing the Crust and Topping

1. In a mixing bowl, combine 1 cup of all-purpose flour, 1 cup of old-fashioned oats, ¼ teaspoon of salt, and ¾ teaspoon of baking soda. Stir until well mixed.
2. Add in 10 tablespoons of melted unsalted butter, ½ cup of packed light brown sugar, and 1 teaspoon of pure vanilla extract. Mix until the mixture becomes crumbly, resembling wet sand.

Baking the Initial Crust

1. Press half of the crumb mixture firmly into the bottom of the prepared baking pan. Use the back of a measuring cup to flatten it evenly.
2. Bake the crust in the preheated oven for 10 minutes, until it's just starting to set but not yet browned.

Making the Lemon Filling

1. In another bowl, whisk together 1 can of sweetened condensed milk, 2 tablespoons of sour cream or plain yogurt, 1 large egg yolk, ¼ cup of freshly squeezed lemon juice, 1 tablespoon of finely grated lemon zest, and ½ teaspoon of vanilla extract. Mix until smooth and creamy.

Assembling the Bars

1. Once the crust has baked, pour the lemon filling over the crust. Use a spatula to spread it evenly across the surface.
2. Sprinkle the remaining crumb mixture evenly on top of the lemon filling to create a delicious topping.

Baking the Bars

1. Bake the assembled bars for an additional 15 minutes, or until the topping is golden brown and the filling is set.

Cooling and Serving

1. Remove the bars from the oven and allow them to cool in the pan on a wire rack for at least 30 minutes.
2. Once cooled, cut into squares and serve. Enjoy the delightful combination of tangy lemon and buttery crumb!

Variations

• Add a handful of fresh blueberries or raspberries for a fruity twist.
• Substitute coconut flour for a gluten-free option.
• Top with a light dusting of powdered sugar or a drizzle of icing for extra sweetness.
• Incorporate a dash of ginger or cardamom for a warm, spiced flavor.

Common Mistakes
