Step 1

Preheat oven to 350° F.

Step 2

In a small mixing bowl, whisk together the flour, baking powder and salt.

Step 3

Cream the butter and sugar in a mixing bowl until light and fluffy, about 3 minutes. Add the 2 egg yolks, and vanilla, and thoroughly mix.

Step 4

Add the dry ingredients and mix until crumbly. Press into a 9 X 13″ baking dish. (The dough will be sticky, so you may need to dust your fingers with a bit of flour.)

Step 5

In a clean mixing bowl, beat the egg whites until stiff peaks form. Continue to beat at medium speed while slowly adding the brown sugar. Then fold in the pecans.

Step 6

With an offset spatula, evenly spread the meringue mixture over the crust. Bake for 20-30 minutes until golden brown.
