Preheat oven to 350 F. Line a baking dish with parchment paper.
Combine all the crust ingredients and press down into the baking dish. Bake for 15 minutes.
In a mixing bowl, combine all the filling ingredients, whisking vigorously until smooth throughout.
Once crust comes out of the oven, pour the filling on top. Bake for another 15-20 minutes.
Let cool fully. After removing the bars from the oven, peel off the parchment paper and slice into squares.
