Preparation

• Preheat the oven to 350 degrees Fahrenheit.
• Line an 8x8 baking pan with parchment paper.
• Add the butter to the microwave and melt for 25 seconds. It won't be fully melted, but should be mostly melted.
• Combine the flour, sugar, butter and salt. Whisk in 2 tablespoons of water and mix until a dough forms.
• If it seems too crumbly, whisk in the third tablespoon of water.
• Press into the baking pan until even.
• Bake for 25 minutes.
• Meanwhile, whisk together the flour and sugar for the filling.
• Whisk in all remaining ingredients until smooth.
• When the crust is done, pour in the filling and bake for 20-25 minutes or until the center looks set.
• Remove from the oven and let cool at room temperature for about 20 minutes, then let set in the fridge for at least 1-2 hours before slicing.
• Slice into 16 squares and enjoy! Store leftovers in the fridge.
