Step 1

Preheat oven to 350 degrees F.

Step 2

Line a 9x13 baking/cake pan with foil (allow the edge of the foil to extend past the ends of the pan to create 'handles' that make removal of the cookie bars easy) and spray the foil with non-stick cooking spray.

Step 3

In a large bowl, stir together the cake mix, eggs and softened butter until thoroughly combined. The batter will be thick and a bit sticky.

Step 4

Use a spatula to spread/press the batter evenly in the lined 9x13 pan.

Step 5

Bake for 15-20 minutes until the lemon bars are baked through and lightly browned.

Step 6

Allow the baked lemon dough to cool and then use the foil 'handles' to gently lift the bars onto a flat surface like a large cutting board or baking sheet.

Step 7

Cut into 15 -20 squares depending on the size of bars you prefer.

Step 8

While the bars are cooling, zest the lemon then squeeze 1/2 the lemon for the fresh lemon juice for the glaze.

Step 9

Prepare the glaze: In a small bowl, whisk together the powdered sugar and lemon juice until smooth. Add additional powdered sugar or lemon juice  as needed until the glaze is thin enough to drizzle over the bars.

Step 10

Drizzle lemon bars with lemon glaze and sprinkle with lemon zest.
