French Macaron with Egg Custard Filling

Part 1: Egg Custard

Ingredients:

Egg yolk - 1

Milk - 3 TBSP

Sugar - 2 TBSP

Milk powder - 1 TBSP

Cake four - 2 tsp

Butter - 1 TBSP

I used 3 egg yolks left from macaron shells, therefore times 3 for all ingredients. 

Steps:

1. In a microwaveable mixing bowl, whisk together egg yolk, sugar and milk. Then mix in milk powder, and flour, finally add butter.

2. Put bowl in microwave oven,  heat 30 seconds, then take out to mix. Continue for 15 second a time until barter looks cooked.

3. When barter is cool down, wrap in a shrink wrap to knead evenly.

Part 2: Macaron Shells

This follow the same ingredients and steps as in the Rose Raspberry French Macaron, except that I did not add any food color.

Part 3: Assemble

Put the egg custard filling in a piping bag and pipe on half of the shells, then sandwich them.
