Healthy Key Lime Cupcakes (gluten-free & refined sugar-free)

Key Lime Cupcakes are light, fluffy cupcakes full of key lime flavor! These cakes are made with lime juice and zest, topped with a tangy sweet cream cheese lime frosting made gluten-free and refined sugar-free.


To make these delicious citrus infused cupcakes I used gluten-free baking flour, zero calorie sweetener (Swerve), eggs, almond milk, coconut oil and of course key limes! And the frosting is just as simple. I used cream cheese, yogurt and zero calorie confectioners sweetener (Swerve). This simple recipe takes about 20 minutes to whip up and just .325 seconds to devour.


There’s something about citrus that makes me crave it on a hot day. Living in Southern California this means I need citrus like everyday between March-September. I’m okay with that because like I love citrus desserts! Here are a few of my favorite citrus recipes I’ve created:


These sweet and tart cupcakes taste just like a slice of key lime pie and they make a perfect party treat. I know this from experience because I took these cupcakes to my friends house for a pool party and they were practically all gone within the first 5 minutes. Like GONE! Everyone devoured these cupcakes in before I could make my rounds and say hi to everyone.
