Poppy Seed Spirals

• 1 cup butter, softened
• 3/4 cup sugar
• 1/4 teaspoon baking powder
• 1/8 teaspoon salt
• 1 egg
• 1 teaspoon vanilla
• 2 2/3 cups all-purpose flour

Instructions:

Beat butter until fluffy, about 30 seconds on medium if using an electric mixer. Add sugar, baking powder, and salt, and combine. Beat in the egg and vanilla. Then beat in flour. Divide the dough in half. Stir poppy and lemon into one half, and leave the other plain. Roll each into a 9x6 rectangle. Roll poppy rectangle onto the plain, and seal them together. Roll up like a jelly roll, wrap in plastic, and chill for 4 to 24 hours until firm. Cut dough into 1/8-1/4-inch slices. Bake at 375º F for 8-10 minutes, 1 inch apart. Transfer to wire rack to cool.
