Method
- Step 1: Preheat your oven to 350°F (175°C). Prepare your baking pan by greasing it and lining it with parchment paper.
- Step 2: In a mixing bowl, combine the chopped rhubarb, granulated sugar, cornstarch, and lemon juice. Stir well to coat the rhubarb and set aside to macerate for about 15-20 minutes.
- Step 3: In another bowl, whisk together the flour, baking powder, and salt.
- Step 4: In a large mixing bowl, cream the softened butter with the powdered sugar until light and fluffy.
- Step 5: Beat in the egg and vanilla extract until well combined.
- Step 6: Gradually add the flour mixture to the creamed butter mixture, mixing until just combined.
- Step 7: Press two-thirds of the dough into the bottom of the prepared baking pan to form the crust.
- Step 8: Spread the macerated rhubarb mixture evenly over the crust.
- Step 9: In a small saucepan, gently heat the milk and 1 tablespoon of vanilla extract until warm. Remove from heat and whisk in the remaining dough until smooth.
- Step 10: Pour the custard mixture over the rhubarb filling.
- Step 11: Bake in preheated oven for 40-45 minutes, or until the custard is set and the top is lightly golden.
- Step 12: Allow the bars to cool completely in the pan before slicing into squares.
Notes
Store the bars in an airtight container in the refrigerator for up to one week. They can also be frozen for up to three months.
