Cream butter and sugar together.

Add egg and extract and mix until well combined.

Stir in flour, mixing until fully incorporated.

Divide dough in half.

Cover cutting board with plastic wrap and press out half of dough into an 8x8 square.

Sprinkle sugars onto the dough in patches.

Use the plastic wrap to to lift and roll up dough - just like sushi.

Repeat with second half and refrigerate dough rolls for 1-2 hours or until nice and firm.

Preheat oven to 375 degrees.

Line baking sheet with parchment paper.

Remove plastic wrap from rolls and cut into 1/4 inch slices.

Place slices about 2 inches apart on cookie sheet.

Bake for 6-8 minutes or until edges just turn golden. Let cool for 1-2 minutes and remove to wire rack.
