St. Patrick’s Day Treat: Lucky Key Lime Donuts

St. Patrick’s Day is coming up on March 17th and to celebrate we’re making these fun themed treats that can be enjoyed by the whole family. These key lime donuts are on the healthier side because they’re baked- not fried (without compromising on flavour!) They’re super tart, flavourful and delicious just like biting into a key lime pie. Enjoy them as is or add a tangy citrus key lime glaze on top. For the full St. Patrick’s Day vibe, top them off with crushed Lucky Charms cereal and marshmallows. This recipe is easy enough for your little leprechauns to help too! 

For this recipe you’ll need a good quality donut pan for baking. Our Ricardo Donut Pan has excellent heat distribution while baking and has a non-stick coating for easy release of the donuts. Prefer silicone? You’ll love our Confetti Donut Pan.


(If you can’t find key limes, regular limes will work as well).

  • ¼ cup key lime juice 
  • 1 cup milk
  • 2 ¼ cups flour
  • 1 cup sugar
  • 1 ½ tsp baking powder
  • ¼ tsp baking soda
  • ¾ tsp salt
  • 1 tsp key lime zest
  • 2 tbs melted butter
  • 2 eggs


  • 1 cup powdered sugar
  • 2-3 tablespoon freshly squeezed key lime or lime juice

Topping (optional):

  • Lucky Charms marshmallows and crushed cereal


  1. Grease your Ricardo donut pan and preheat oven to 425 degrees
  2. Add ¼ cup key lime juice and milk into a bowl and set aside
  3. Mix flour, sugar, baking powder, baking soda, salt and lime zest in a large bowl
  4. Mix together the melted butter, eggs, and key lime mixture. Add to your large bowl
  5. Whisk well and spoon mixture evenly into the Ricardo Donut Pan.  Fill each donut mould about ¾ full
  6. Bake for 8-10 minutes
  7. Let the donuts cool in pan for 5 mins. Remove the donuts and transfer to a cooling rack
  8. To make the glaze: Whisk together the powdered sugar and squeezed lime juice
  9. Dip your donuts in one at a time and return back to wire rack
  10. Top with Lucky Charms crushed cereal and marshmallows (optional).  Another great topping is crushed graham crackers.

Hope you have a magically delicious St. Patrick’s Day!
