WHAT ARE BUTTERFLY CUPCAKES?
Butterfly cupcakes, also known as butterfly cakes, are a type of cupcake that is filled with cream or jam and decorated with wings made from the cupcake cut in half. The cupcake is first baked in a cupcake liner, and once it's cooled, a small circular portion is cut from the top of the cake. This top portion is then cut in half, and the halves are placed in a butterfly-like shape, with the cream or jam filling spread in the center.
INGREDIENTS
We use a favorite almond flour cupcake recipe for these lemon curd butterfly cakes.

- Almond flour - use finely ground almond flour
- Butter - the melted butter can be substituted with coconut oil
- Sweetener - we used allulose but any other low carb sweetener such as monkfruit or Swerve could be used.
- Lemon curd - We use homemade sugar free lemon curd but you could use a sugar free berry jam too.
HOW TO MAKE KETO BUTTERFLY CUPCAKES
These are a fun family cupcake to make. Bake any keto vanilla muffin, cut a centre out, fill it and top with the sponge centres, cut into wings.

STORAGE
Keep the assembled cupcakes in an sealed container in the fridge. They should last up to 5 days, but are best enjoyed fresh.
RECIPE TIPS
These low carb cupcakes can be made with coconut flour in place of the coconut flour. Our apple pie muffin recipe can be used.
Add lemon juice to the cake butter for a stronger lemon taste.
Fill the cupcakes with a mixture of whipped cream and lemon curd for a softer lemon flavor.
