How to Make Banana Custard Slice

  1. Preheat your oven to 350°F (175°C). Prepare a 9x13 inch baking pan.
  2. Make the shortbread crust: In a bowl, cream together the butter and sugar until light and fluffy. Beat in the egg yolk. Gradually add the flour and salt, mixing until just combined. Press the dough evenly into the prepared pan.
  3. Bake the crust for 15-20 minutes, or until lightly golden. Let cool completely.
  4. Make the banana custard: In a saucepan, whisk together the sugar, cornstarch, and salt. Gradually whisk in the milk until smooth. Add the egg yolks and vanilla extract.
  5. Cook over medium heat, stirring constantly, until the custard thickens and comes to a gentle boil. Remove from heat and stir in the mashed bananas.
  6. Pour the banana custard over the cooled shortbread crust. Spread evenly.
  7. Refrigerate for at least 1 hour, or until set.
  8. Serve chilled and enjoy!
