Ingredients

  • 1 c. milk
  • 1/4 c. flour
  • 1 c. butter or margarine
  • 1 c. sugar
  • 2 tsp. vanilla

Instructions

  1. Cook milk and flour over medium heat until thickened.

  4. Gradually add the cooled custard to the butter mixture, beating until smooth.
  5. Add vanilla and beat until combined.

Tips & Substitutions

For a smoother custard, ensure the milk and flour mixture is completely cool before adding it to the butter and sugar. If you prefer a lighter texture, you can substitute half of the butter with cream cheese. If you're short on time, consider using a store-bought vanilla pudding mix as a shortcut, just add it to the creamed butter and sugar mixture.

Serving Suggestions

This custard frosting pairs beautifully with a rich chocolate cake or a light vanilla sponge. For added flavor, consider garnishing with fresh fruit or a drizzle of chocolate sauce. It also works well with desserts like Stollen(German Christmas Bread) if you are looking for a festive touch.

Storage & Reheating

Store any leftover custard frosting in an airtight container in the refrigerator for up to a week. When ready to use, let it sit at room temperature for about 30 minutes to soften. You can also briefly re-whip it to restore its fluffy texture before frosting another cake.

Frequently Asked Questions

Can I make this frosting ahead of time?

Yes, you can prepare the custard frosting a day in advance. Simply store it in the refrigerator, tightly covered. Remember to let it come to room temperature and re-whip it before using to ensure the best consistency.

What if my custard is lumpy?

If your custard has lumps, you can blend it in a food processor or use an immersion blender to achieve a smooth texture before mixing it with the butter and sugar. Make sure to cool it properly to avoid curdling during cooking.

Can I use margarine instead of butter?

Absolutely! Margarine can be used as a substitute for butter in this recipe. Just keep in mind that the flavor may be slightly different, but it will still create a creamy and delicious frosting.
