👨‍🍳 Step-by-Step Instructions

1️⃣ Preparing the Cake Batter

  1. Preheat the oven to 350°F (175°C) and grease two 6-inch cake pans with coconut oil or vegan butter.
  2. In a large bowl, whisk together the gluten-free flour, almond flour, baking powder, baking soda, and salt.
  3. In a separate bowl, mix the wet ingredients: applesauce, melted coconut oil, plant-based milk, apple cider vinegar, vanilla extract, and sweetener.
  4. Gradually combine the wet ingredients into the dry ingredients, stirring until smooth.
  5. Divide the batter evenly into the two cake pans.

2️⃣ Baking the Cake Layers

  1. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
  2. Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

3️⃣ Making the Bluey-Themed Frosting

  1. Using a hand or stand mixer, beat the vegan butter until smooth and creamy.
  2. Slowly add in the powdered monk fruit sweetener, mixing until light and fluffy.
  3. Add the vanilla extract and plant-based milk (1 tbsp at a time) until the frosting reaches a spreadable consistency.
  4. Divide the frosting into two bowls:
  • One part stays white (for Bluey’s eyes and face details).
  • The other is dyed blue using natural food coloring.

  3. Smooth the frosting evenly for a clean, professional look.

5️⃣ Creating Bluey’s Face & Details

  1. Using the white frosting, pipe Bluey’s eyes and facial features.
  2. Add small white circles to create her signature eye highlights.
  3. If you have an edible cake topper, place it on the cake as a finishing touch.

6️⃣ Adding the Final Touches

  1. Decorate the sides of the cake with vegan sprinkles.
  2. Use additional frosting to pipe Bluey’s paws or fun birthday messages.
  3. Chill the cake in the fridge for 15 minutes before serving so the decorations set.
