Ingredients

Directions

Make the frosting

  1. Mix the first four ingredients together in a saucepan until well blended.

  2. Gradually add the milk.

  3. Add the margarine.

  4. Cook over medium heat, stirring constantly until thick and smooth.

  5. Remove from heat occasionally to prevent sticking or lumping.

Ice and serve

  1. Ice the cake while the frosting is still warm.

  2. Ice two 9‑inch layers.

  3. Cut the recipe in half for a single‑layer cake or cupcakes.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: beta-damascenone (apple, rose).

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cornstarch
Thickens the frosting as it cooks, giving it a smooth, spreadable body.
Cocoa
Provides the chocolate flavour and dark colour.
White sugar
Adds sweetness and helps give the frosting a smooth texture.
Brown sugar
Adds sweetness and a richer, caramel-like flavour.
Margarine
Adds fat for richness and a smooth, glossy mouthfeel.

The step that matters

Cook while stirring constantly. Cornstarch thickens only when heated, and it can scorch or form lumps if it settles on the pan bottom. Constant stirring keeps heat even and the starch dispersed, so the frosting becomes thick and smooth.

Swap the cocoa

How well each one fits the dish's main ingredients (sugar, milk):

  1. Cocoathe original
  2. Almondfits about as well
  3. Chestnutfits about as well
  4. Peanutfits less well

Fit is the average pairing score against sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
