Preheat oven to 350°F. Grease and flour a 9x13 pan.
Melt the butter in a saucepan or in the microwave; let cool slightly.
In a mixer, beat the eggs and the sugar. Add the flour, salt and baking powder. Then slowly add in the melted butter and almond extract. Scrape the sides of the bowl down and stir once more.
Pour into the prepared 9x13 pan.
Sprinkle with sliced almonds and sugar. I use about 2 tablespoons each.
Bake at 350°F for 30 minutes or until just lightly brown on top. Do not overbake.
When cool, cut into squares and enjoy.
