Recipe type: Bar Cookie
Serves: 24
  • ½ cup softened butter
  • ¼ cup + 2 Tbsp Canola or Vegetable oil
  • ½ cup + 2 Tbsp granulated sugar
  • ¼ cup + 2 Tbsp powdered sugar
  • 1 egg
  • 1½ Tbsp fresh squeezed lemon juice
  • 1 tsp lemon zest
  • 1 tsp vanilla
  • 2¾ cup all-purpose flour
  • ½ tsp salt
  • ½ tsp baking powder
  • pinch of baking soda approx 1/16 of a tsp
  • a little extra granulated sugar for sprinkling on top of dough before baking (about 1-2 TBSP)
  • ¼ cup softened butter
  • 1½-1¾ cups powdered sugar
  • pinch of salt
  • 1-2 tbsp fresh lemon juice (depending on how tart you want your icing, I use 1½)
  • Milk or cream to desired consistency...1-2 tbsp, I drizzle it in until frosting looks nice and creamy yet still a little thick.
  • DIRECTIONS FOR FROSTING: Mix butter, powdered sugar, salt and lemon juice with a hand mixer or whisk. Add in the milk or cream until nice and smooth. Frost bars when they are completely cooled. I prefer to keep bars in the fridge because I like them cold, but you can leave them at room temperature if desired.
  1. DIRECTIONS FOR COOKIE BARS: Preheat oven to 350 degrees
  2. Lightly butter or spray with cooking spray, a 9x13 pan and set aside
  3. Using your mixer thoroughly cream butter, oil, granulated sugar and powdered sugar until combined
  4. Add egg, lemon juice, lemon zest and vanilla and mix until well combined
  5. Add flour and sprinkle in salt, baking powder and baking soda, mix for approx 1 minute or until completely combined
  6. Spread/press cookie mixture evenly into greased 9x13 pan. (like to use a sandwich baggie on my hand to press it down evenly. Spray baggie with cooking spray if necessary)
  7. Evenly sprinkle 1-2 tbsp of sugar over the uncooked bars before placing them in the oven
  8. Bake at 350 degrees for 14-16 minutes or until edges are just barely turning a light brown. Do not over bake or bars will be dry.
  9. Let cool completely and frost with Lemon Butter Cream frosting recipe before cutting.
