These Tropical Pineapple Oat Bars are a delightful treat, combining a sweet pineapple filling with a buttery oat crust and crumbly topping.
In a saucepan, combine the sugar and cornstarch, then stir in the crushed pineapple with its juice.
Stir constantly to prevent the mixture from sticking to the bottom of the pan.
Cook the mixture over medium heat until it thickens, then set aside to cool completely.
Allowing the filling to cool prevents it from softening the crust.
In a mixing bowl, combine the oatmeal, salt, brown sugar, flour, and baking powder.
Mix thoroughly to ensure even distribution of the ingredients.
Work the butter into the dry mixture until it resembles coarse crumbs.
Use your hands or a pastry cutter for the best results.
Press two-thirds of the crumb mixture into the bottom of an ungreased 9x13 baking pan, forming an even layer.
Press firmly to create a solid base for the filling.
Spread the cooled pineapple filling evenly over the crust.
Ensure the filling is evenly distributed for consistent flavor.
Sprinkle the remaining crumb mixture over the filling to form a topping.
Distribute the topping evenly for a uniform appearance.
Bake in a preheated oven at 350°F (175°C) for 20 minutes or until golden brown.
Check the bars towards the end of the baking time to avoid overbrowning.
Allow the bars to cool completely in the pan before cutting into squares.
Cooling ensures clean cuts and prevents the bars from crumbling.
