🧁 Ingredients (Makes 8–10 cupcakes)

Cupcakes:

  • ¼ cup coconut flour

  • ½ cup erythritol (granulated)

  • 3 large eggs

  • ⅓ cup sour cream or full-fat Greek yogurt

  • ¼ cup melted butter or coconut oil

  • 1 tsp vanilla extract

  • 1½ tsp baking powder

  • Pinch of salt

Frosting:

  • ½ cup unsalted butter, softened

  • ½ cup powdered erythritol

  • 1 tsp vanilla extract

  • 2–3 tbsp heavy cream (as needed for texture)

  • Natural food coloring (purple, green, orange)

Decoration:

  • Edible candy eyeballs (sugar-free if possible, or make your own with coconut & chocolate chips)

  • Optional: keto sprinkles, shredded coconut, or sugar-free chocolate drizzle


👩‍🍳 Instructions

Step 1: Preheat Oven & Prep

Preheat oven to 350°F (175°C). Line a muffin tin with festive cupcake liners.


Step 2: Mix Wet Ingredients

In a bowl, whisk together eggs, sour cream, melted butter, vanilla, and sweetener until smooth.


Step 3: Add Dry Ingredients

In a separate bowl, mix almond flour, coconut flour, baking powder, and salt.
Gradually add to the wet mixture and stir until fully combined.

💡 Tip: The batter will be slightly thick—don’t overmix.


Step 4: Bake

Scoop batter into cupcake liners, filling each ¾ full.
Bake for 18–22 minutes, or until a toothpick inserted comes out clean.
Cool completely before frosting.


Step 5: Make the Frosting

Beat softened butter with powdered erythritol until fluffy (2–3 minutes).
Add vanilla and cream. Continue whipping until smooth and pipeable.
Separate into bowls and tint each batch with a few drops of different food coloring.


Step 6: Decorate the Monsters

Pipe frosting onto each cooled cupcake using a star tip or round nozzle.
Top with 1–3 candy eyeballs for a “monster” look.
Get creative: some can have one eye (cyclops), others multiple or slanted for expression.

Optional: Add a sprinkle of shredded coconut as “monster hair” or drizzle with sugar-free chocolate.
