Why Use Cake Mix for Lemon Bars?
Traditional lemon require making a buttery shortbread crust from scratch—but with cake mix, you can skip the extra steps and still get a delicious, soft, and chewy texture.

✔️ Taste & Texture Differences
Using cake mix instead of a traditional crust gives lemon bars a:
✔️ Softer, more cake-like texture instead of a firm shortbread base.
✔️ More intense lemon flavor when using a lemon-flavored mix.
✔️ Moist & chewy consistency rather than crumbly.
If you love simple, no-fail desserts, this method is a game-changer!
