St. Patricks Day calls for all the green keto treats, and these are a rich, vibrant green without the need for any artificial colourings.
These low-carb cupcakes get their gorgeous green from a healthy dose of baby spinach, whereas the frosting is flavoured with matcha giving it a soft pale green hue. We flavoured ours with vanilla but you can even go with lime and add about a tablespoon of fresh lime juice and a teaspoon of fine lime zest.
Note that these cupcakes are slightly dense from the spinach, and though they will rise in the oven, they will flatten when cooling. This creates a flat base perfect for the delicious frosting to sit on! If you prefer them fluffier, simply add 1 to 2 more eggs, plus about 1/4 cup (25 g/ 0.9 oz) of unflavoured whey protein powder or egg white protein powder.

Ingredients (makes 12 cupcakes)
Cupcakes:
Matcha frosting:
- 1 1/4 sticks butter, at room temperature (140 g/ 5 oz)
- 140 g cream cheese, at room temperature (5 oz)
- 1 1/4 cups powdered Erythritol or Swerve (200 g/ 7.1 oz)
- 1 tbsp powdered matcha (5 g/ 0.2 oz)
- 2 tsp sugar-free vanilla extract
Instructions
- Preheat oven to 180 °C/ 355 °F (conventional), or 160 °C/ 320 °F (fan assisted). Add dry ingredients to a large bowl and mix well.
- Add the almond milk, eggs, butter, vanilla and spinach to a blender and turn on blender at the slowest speed, then slowly increase to high speed, blending until you have a smooth green cream with no pieces.
- Pour the wet mixture into the dry mix and stir until just combined.
- Scoop into a cupcake tray lined with paper or silicone liners, filling 3/4 way up.
- Bake 20 to 25 mins or until an inserted skewer comes out clean.
- Cool in the pan for 10 minutes, then cool completely on a wire rack.
Note that the tops may sink in slightly — this is fine as you will be filling them with the creamy cupcake frosting.
- To make the frosting, add the butter and cream cheese to a large bowl and beat with an electric stand mixer or hand held mixer on medium speed until combined.
- Add the sweetener, a spoonful at a time, beating after each addition. Once it's all been added, continue beating until pale and fluffy, around 8 to 10 minutes. Add the vanilla and matcha powder and beat until combined.
- Spoon in a piping bag and decorate each of the cupcakes using a star piping tip or any other piping tip. Alternatively you can simply use a spoon.
- The cupcakes can be stored in the fridge for up to 5 days or in the freezer for up to 3 months.
