Ingredients Gather the following uncomplicated ingredients for your 2-Ingredient Lemon Bars:

  • 1 box (18.25 ounces) of lemon cake mix
  • 1 can (14 ounces) of sweetened condensed milk
  • Optional: Powdered sugar for dusting


1. Preheat Your Oven:

  • The journey begins with preheating your oven to 350°F (175°C). This ensures that your lemon bars receive the ideal baking environment.

2. Create the Base:

  • In a mixing bowl, unite the lemon cake mix and sweetened condensed milk. Stir vigorously until the mixture reaches a dough-like consistency.

3. Press the Dough:

  • Grease a 9×13-inch baking dish and transfer the lemony dough into it. Utilize your hands or the back of a spoon to press the mixture evenly across the base, ensuring a smooth, level surface.

4. Bake to Perfection:

  • Position the baking dish inside the preheated oven and bake for approximately 20-25 minutes. Keep a watchful eye on your creation, as you’ll want the edges to acquire a golden hue and a toothpick inserted in the center to come out clean.

5. Cool and Cut:

  • Once your lemon bars have achieved their golden glory, take them out of the oven and allow them to cool down inside the baking dish. After reaching a comfortable temperature, begin to slice them into squares or bars, adjusting the size according to your preference.

6. Optional Dusting:

  • If you fancy a finishing touch, consider dusting your lemon bars with powdered sugar, adding an extra layer of sweetness.

Cooking Notes

  • The key to the simplicity of these lemon bars lies in the lemon cake mix, which effortlessly serves as both the crust and the filling. If you feel adventurous, don’t hesitate to experiment with different cake mix flavors to create unique variations.


  • Customize your lemon bars with exciting variations:
  1. Berry Bliss: Before baking, lay a layer of fresh berries like blueberries or raspberries on top of the base for a fruity explosion.
  2. Zesty Zing: Post-baking, squeeze fresh lemon juice and zest onto the bars for an additional burst of citrusy delight.

Keto Version

Opt for a keto-approved cake mix or create a low-carb crust from almond flour sweetened with erythritol. To replace sweetened condensed milk, utilize a keto-friendly alternative. Remember to consider a keto-compatible powdered sugar for dusting.
