  • 1/2 cup melted coconut oil or butter
  • 1 tsp vanilla extract

For the Frosting:

  • 2 tbsp powdered sweetener
  • 1 tbsp heavy cream or unsweetened almond milk
  • Natural food coloring (blueberry juice, beet juice, spirulina, etc.)

  • Edible glitter or sprinkles (low-carb or vegan-friendly)
  • Fresh mint leaves or lemon slices for garnish

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 325°F (160°C) . Grease an 8-inch round cake pan or line with parchment paper for easier removal.

Pro Tip: Use silicone molds for even easier shaping and release.


Step 2: Mix Dry Ingredients

In a mixing bowl, combine:

  • Almond flour
  • Coconut flour
  • Powdered sweetener
  • Baking powder
  • Salt

Mix well until evenly incorporated and slightly fluffy.

Note: Coconut flour is highly absorbent—measure carefully and sift if possible.


Step 3: Add Wet Ingredients

To the dry mixture, add:

  • Melted coconut oil or butter
  • Egg or flax egg
  • Vanilla extract

Stir until smooth and slightly thick—but still scoopable.

Pro Tip: The batter should be firm but moist. Add more egg whites or cream if too thick.


Step 4: Pour Into Pan

Transfer the batter into the prepared cake pan and smooth the top with a spatula.

Bake for 25–30 minutes , or until a toothpick inserted comes out mostly clean.

Let cool completely before frosting.


Step 5: Decorate Like Fireworks!

Beat cream cheese or vegan frosting with powdered sweetener and heavy cream.

Divide into small bowls and tint with natural food coloring:

  • Beet juice for red
  • Blueberry juice for blue
  • Spinach or spirulina for green

Use a piping bag or spoon to create firework starbursts on top of the cooled cake.


Step 6: Garnish and Serve!

Once frosted, sprinkle with:

  • Crushed freeze-dried berries for color and crunch
  • Edible glitter or low-carb sprinkles
  • Sparkler candies (if not strict keto)

Serve chilled or at room temperature with:

  • Black coffee or herbal tea
  • As part of a keto charcuterie board
  • Over chia pudding or yogurt for parfait-style dessert
  • In a handheld wrap for fusion flair

Enjoy every soft, spiced bite of your Fireworks Sugar Cookie Cake !

Fireworks Sugar Cookie Cake – Sweet, Festive & Perfectly Low-Carb!

Description

A delightful blend of buttery sweetness, colorful M&Ms, and sprinkles!


Ingredients

🧈 ¾ cup (170g) unsalted butter, softened
🍬 ¾ cup (150g) granulated sugar
🥚 1 large egg
🍦 1 tablespoon vanilla extract
🧂 ½ teaspoon baking soda
🧂 ½ teaspoon salt
🧂 ½ teaspoon cream of tartar
🌾 2 cups (248g) all-purpose flour
🍬 1 cup M&Ms (patriotic for 4th of July)
🌈 ½ cup jimmie sprinkles (red and white for 4th of July)
For the frosting:
🧈 3 tablespoons (38g) unsalted butter, softened
🍬 1 ½ cups (170g) powdered sugar
🍦 1 teaspoon vanilla extract
🧂 ⅙ teaspoon salt
🥛 2 tablespoons (30ml) heavy whipping cream or milk


Instructions

Preheat oven to 350°F. Line a 9” round cake pan with foil and spray with nonstick cooking spray.
Make the cookie cake: Beat butter and sugar with a hand or stand mixer until creamy. Beat in egg and vanilla, then mix in baking soda, salt, and cream of tartar. Slowly mix in flour. Stir in M&Ms and sprinkles.
Press batter into prepared pan, pressing more M&Ms onto the top as desired. Bake for 19-22 minutes or until the edges are just turning a light golden brown. It’s better to under bake this dough than over bake it. The cake will continue cooking a bit as it cools, so err on the side of underdone for the best tasting cookie. Let it cool completely before frosting.
Make the frosting: Beat butter until smooth, then slowly beat in powdered sugar until crumbly. Add salt and vanilla, then add 1 tablespoon of heavy whipping cream. Beat until smooth, adding more a teaspoon at a time to get a spreadable texture.
To frost: Use a 1M tip and a ziplock or piping bag to decorate the cookie cake. Top with more sprinkles and M&Ms.
Store loosely covered for up to 2 days.
