Preheat your oven to 350°F (175°C). Grease and line a 9x9-inch baking pan with parchment paper, leaving an overhang for easy removal.
In a large mixing bowl, combine the flour, oats, brown sugar, cinnamon, baking soda, and salt. Stir until well mixed.
Pour in the melted butter and mix until the ingredients are evenly moistened. Reserve 1 cup of this mixture for the topping.
Press the remaining oat mixture evenly into the prepared baking pan to form the base layer. Set aside.
In a medium saucepan, combine the raisins, granulated sugar, and water. Cook over medium heat, stirring frequently, until the raisins plump and the mixture begins to simmer, about 5–7 minutes.
In a small bowl, whisk the cornstarch and lemon juice together until smooth. Stir this mixture into the saucepan with the raisins.
Continue to cook the raisin mixture, stirring constantly, until it thickens, about 2–3 minutes. Remove from heat and stir in the vanilla extract. Allow the mixture to cool slightly.
Spread the raisin filling evenly over the oat base in the pan.
Sprinkle the reserved 1 cup of oat mixture evenly over the raisin filling, pressing gently to adhere.
Bake in the preheated oven for 30–35 minutes, or until the top is golden brown and the filling is bubbling slightly at the edges.
Remove the pan from the oven and allow the bars to cool completely in the pan on a wire rack.
Using the parchment paper overhang, lift the bars out of the pan and place them on a cutting board. Slice into 16 bars and serve.
Store any leftovers in an airtight container at room temperature for up to 5 days.
