Lemon Poppy Seed Bars Recipe

These bars are some of my favorite things- lemon, sugar cookies, and poppy seeds - all rolled into one. Chewy and dense, they are the perfect dessert! They make a lot, so they are awesome for potlucks or parties.

  • 1 cup unsalted butter at room temperature
  • 2 cups sugar
  • 4 large eggs
  • teaspoons lemon extract
  • 4 cups flour
  • 1 teaspoon salt
  • ½ teaspoon baking soda
  • 4 teaspoons poppy seeds


  • ½ cup butter softened
  • ¼ cup milk
  • teaspoons lemon extract
  • 4 cups powdered sugar
  • a couple of drops yellow food coloring (optional)


  • Preheat oven to 375 degrees. Spray a large 15x10x1" baking sheet (cookie sheet) with non-stick cookie spray.
  • In a large bowl, cream butter and sugar until fluffy (I used a mixer, but you could also do it by hand). Add eggs, one at a time, mixing after each one. Mix in lemon extract.
  • In a separate bowl, mix together flour, salt, baking soda, and poppy seeds. Add in with wet ingredients and mix until just combined.
  • Spread the dough all the way to the edges in the prepared cookie sheet . I have found that it's easier to just use your hands to spread it (the dough may be sticky, so spray hands with non-stick cooking spray to make it easier to spread).
  • Bake for 10-15 minutes or until dough is a light golden brown. Cool completely before frosting.
  • For frosting: Mix frosting ingredients together until completely combined. Spread over pan of bars.
