These soft and chewy lemon cake mix cookies are made with just 3 ingredients. The perfect quick treat using a box mix and a clever cookie hack!

If you’ve got a box of lemon cake mix sitting in your pantry, you’re just a few steps away from the easiest and yummiest cookies ever. These lemon cake mix cookies are soft, chewy, and packed with zesty flavour – and they come together with just a handful of ingredients. It’s one of those clever little baking hacks that feels like magic (with zero fuss).
Whether you’re short on time, baking with the kids, or just craving something citrusy and sweet, this recipe is a total win. You’ll never look at a box cake mix the same way again!
NOTE: I use the Greens Lemon Cake Mix because it works well (if it ain’t broke, why fix it?) and I love that it comes with icing mixture, which is great to roll the cookies in before baking, and then also sprinkle on once cooked.

How to make lemon cake mix cookies

Ingredients:
Optional: extra icing sugar (about 1 cup) if your mix doesn’t include any
1 x 420g packet lemon cake mix (I use one that includes the icing sugar mix)
1 egg
100g butter, melted
- Preheat the oven
Set your oven to 170ºC (fan-forced). Line a baking tray with baking paper.
- Mix the dough
In a medium bowl, combine the lemon cake mix, egg, and melted butter. Stir until a thick dough forms. Pop the dough into the fridge for 30 minutes – this helps it firm up and makes it easier to roll.
- Roll into balls
Once chilled, roll the dough into small balls using your hands.
- Coat in icing sugar
Pour the lemon icing sugar mix (or regular icing sugar) onto a plate. Roll each cookie dough ball into the sugar, coating generously.
- Bake
Place the sugar-coated dough balls onto the lined tray, leaving space between each cookie. Bake for 12–15 minutes or until lightly golden and just set.
- Cool and sprinkle
Allow cookies to cool slightly, then dust with extra icing sugar if desired. Serve and enjoy!
