Ingredients

  • 1 Duncan Hines Lemon Cake Mix OR Homemade Lemon Cake Mix (see notes below)
  • 2 eggs room temperature
  • cup vegetable oil
  • Lemon zest or lemon extract I prefer lemon zest, but either is fine
  • Glaze
  • 1 cup powdered sugar
  • 2 tbsp lemon juice - fresh squeezed to get the glaze to the right consistency

Instructions

  • Preheat the oven to 350F/175C and prepare a 8 x 8 baking pan by spraying it with non stick spray and then lining with parchment paper.  
  • In a large bowl combine cake mix, eggs, lemon zest and oil together and blend well with a hand mixer on low speed, gradually increasing to medium speed, until the batter is well mixed. 
  • Pour the lemon batter into the prepared baking pan, making sure it is spread evenly with a rubber spatula.
  • Bake for 18  to 25 minutes – starting with 20 minutes and if the top of the brownies are starting to crack it is close to being done.
  • You don’t want to overbake.  The brownies should be a bit chewy and gooey in the center, and not raw. Complicated? Not at all.  
  • Cool the brownies on a wire rack until completely cooled.  
  • While the brownies are cooling, mix up the lemon glaze and then apply to the top of the brownies.
  • Then using the sides of the parchment paper, lift them out of the pan, and cut into individual lemon bars. You should get 12 bars with this recipe.

Notes

Homemade cake mix option: You can also make your own lemon cake mix using the homemade recipe included below. For best results, use the amount specified for this recipe rather than automatically substituting the entire batch.
Ingredients
1½ cups granulated sugar
2 medium lemons zested
2¾ cups cake flour (regular flour - 2 1/2 cups)
4 teaspoons baking powder
1 teaspoon fine sea salt or Himalayan salt
  Instructions
Zest both lemons over your large mixing bowl.
Add the sugar, and then combine the zest and sugar together using your fingers.
Next add in the cake flour, baking and salt. Use a whisk to combine.
Store this cake mix in a mason jar or other air-tight container, and store in your pantry until you are ready to use it. (about a month)
