Preheat your oven to 350°F (175°C).

Grease a 9x13 inch baking pan with butter or cooking spray.

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

In another bowl, beat the softened butter and granulated sugar until light and fluffy.

Crack in the egg and add the almond extract, mixing until combined.

Gradually add the dry mixture to the wet mixture, stirring until just combined.

Pour the batter into the prepared pan and spread it evenly.

Spoon the apricot preserves over the batter and swirl gently with a knife.

Place the pan in the preheated oven and bake for 30 minutes, or until the edges are golden brown.

Allow the bars to cool in the pan for about 10 minutes, then cut into squares.
