Unicorn party


6 tablespoons softened unsalted butter
2 bags  regular  Marshmallows
Blue, purple, & pink food coloring
3/4 cup vanilla cake mix
12 cups rice bubbles
1 1/3 cups rainbow hundreds and thousands,
6 cups buttercream or canned vanilla frosting
2 1/2 tablespoons assorted sprinkles (pearl dragees/stars etc.) plus extra for garnishing if desired
1 tube black decorating icing
8 flower shaped cake decorations
8 birthday candles


Grease a large microwave safe bowl generously with 2 tablespoons butter.

Remove 2 marshmallows from each bag & set aside.

Place 1/3 of the remaining marshmallows in the bowl & microwave on high for 30 seconds, then stir. Repeat 1-2 more times or until marshmallows are melted & smooth.

Stir in 4-5 drops blue food coloring or enough to reach desired shade. Stir in 1/4 cup cake mix, then stir in 4 cups of cereal.

Once combined, gently mix in 1/3 cup jimmies.

Press mixture into a lightly greased 9 inch springform pan. Allow to set for 30 minutes, then remove & set aside.

Repeat the same process twice more with remaining 2 colors.

Once all layers are set, use a 3 1/2 inch round cutter to cut out the center of the purple layer.

Enjoy center as a cook’s treat!

Unicorn Party

Set blue layer on a cake plate & spread top with frosting. Place purple layer over blue layer, & frost the top.

Pick out 16 pink jimmies from the remaining sprinkles & set aside.

Stir assorted sprinkles into the hundreds and thousands & pour into the well of the purple layer. Top with the pink layer.

Frost top & sides. Score frosting on top with 8 equal slices.

Divide remaining frosting equally into 3 bowls & tint each with blue, purple, & pink coloring.

Fit 3 piping bags with assorted tips (I used 1 star, 1 flower, & 1 leaf.) Pipe manes over each slice.

Pipe on the eyes with black icing. Adhere coloured hundreds and thousands as nostrils.

Using a kitchen shears, cut remaining marshmallows in half width wise. Cut each piece in half again.

Pinch together uncut sides to form little ears. Brush insides with a bit of pink coloring & adhere to cake.

Garnish with additional sprinkles, cake decorations, & candles.
