Do you find that as we emerge from the cold, dark winter, that you are craving light and bright flavours?

I definitely am! When the weather starts to warm up and the sun is shining bright I always gravitate to flavours like lemon and lime. This triple lemon cake is one of my favourite spring time recipes! It is perfect for Mother’s Day Brunch.

Local fruit won’t be ready for a couple of months when the first crops of strawberries are upon us, but I just can’t wait that long to start baking with fresh fruit!

Serve these coconut lime bars cut small for a treat or large for a decadent dessert

Tips for the perfect bar:

  • lining your baking pan with parchment paper makes it easy to lift them out for easy cutting
  • run a sharp knife under hot water before each cut will give you nice, cleanly cut edges
  • the coconut can be toasted in the oven or in a frying pan up to 3 days before and stored in an airtight container
  • feel free to substitute regular limes if you can’t find key limes, the flavour is just as yummy
  • cut small for a snack or cut into larger squares and serve with whipped topping and garnish with fresh limes for a delicious dessert

I always use parchment paper when baking bar or squares. When it is time to cut the squares simply lift them out of the pan by gripping the parchment paper and lifting out.

If I am serving these as a dessert, I will make a thin cut all the way around the edges before cutting into large bars. Trust me, those edges won’t go to waste!!

These coconut lime bars are exactly the flavours I look forward to each spring while waiting for fresh local fruit to hit the market!
