Toasted Coconut and Key Lime Bundt Cake

This Coconut Key Lime Bundt Cake is a personal favourite. It has a buttery crumb cake with hints of coconut with a delicious balance of sweetness and lime. Perfect as an after-dinner dessert or to have on your dessert table at your next party. Better yet, make this today and I promise it won’t last long, even if you are the only one enjoying it!

How to make Coconut Keylime Bundt Cake

Start by toasting 1 cup of shredded coconut in a preheated oven. Keep an eye on this as it doesn’t take long to go from toasted to burnt. While the coconut is toasting lightly butter, then flour, your Bundt pan. When the coconut is golden brown remove from the oven to cool.

In the bowl of a stand mixer add the butter and granulated sugar, then whisk to combine until its light and fluffy. Next, add the eggs, one at time, beating after each addition to fully incorporate.

Place the cooled toasted coconut into a blender and pulse until it is chopped up finely.

Add the toasted coconut crumbs, the lime juice, and zest into the butter/egg mixture. Mix well until it is well combined and evenly mixed through the cake batter.

Finally, in a small bowl combine the flour, salt, and baking powder. In a separate bowl add buttermilk and the vanilla extract. Now adda bit of flour mixture into the cake batter and stir to combine. Add half the buttermilk mixture again stirring to combine. Repeat this process until all ingredients are add, you should start and end with the dry ingredients.

Flour, milk, flour, milk, flour for five additions in total.

Scoop in the toasted coconut/key lime cake batter into the prepared pan. Use an offset spatula to spread the cake evenly into the pan. Place into the preheated oven and bake until golden brown.

Once the cake is removed from the oven allow to cool about 30 minutes before inverting and removing from the Bundt pan. Let it cool another completely before glazing.

How to make the glaze

Add icing sugar, lime juice, and vanilla extract to a bowl and whisk to combine. I like this glaze to be fairly thin, but you can add more icing sugar if you like a thicker glaze. I also like to add just a bit more lime zest to the top for a pop of flavour, and colour.

Pro Tip: If you can’t find key limes don’t hesitate to still make this cake, you can use regular limes, and it’s still delicious. Or even add a touch of lemon juice to give the floral notes that key limes have and is missing in regular limes.

    Hi Terri, This looks delicious. I wanted to let you know that coconut is not on the list of ingredients. It is in the description and preparation, but not the list. I thought you might want to add it. Cheers!
