Use this delicious filling to fill cupcakes or your favorite layer cake. The microwave makes it fool-proof! Use different extracts to vary the flavor; almond and mint are both really good.

  • Whisk eggs in a separate small bowl until pale and frothy. Whisk 1/3 cup of the milk mixture into eggs gradually, then whisk egg mixture into remaining milk mixture gradually until smooth custard forms. Heat custard in microwave on high until thickened, about 2 minutes more. Cool slightly; stir in vanilla extract. Chill custard in refrigerator until completely cooled, about 30 minutes.

Instead of the flour I used 3T of cornstarch as someone suggested. Did mine on stove top worked out wonderfully. I did use 2t of vanilla and next time may reduce sugar by 1/4 cup as it is super sweet but really good! Read More

My 12 y/o tried to make it and it completely did not turn out. It was a watery mess with lumps at the bottom. I tried again and was not having success. I microwaved much longer than the recipe called for and it did finally thinken, but it was not smooth. I think that if you have to edit the recipe to make it work, it's not a 5 star recipe. Obviously stove top would have been better; it always is. And I would suggest following the cornstarch directions on other reviews. That probably would have made a positive difference. It worked out. It tasted good. I'm not sure I strongly recommend the recipe though, definitely not as written. Photo is of Extreme Chocolate Cake with this as the custard filling, and Kit Kats, per the birthday boy's request. Read More

I made mine on the stovetop. Bring milk and sugar just to a boil, then temper that into your eggs/salt/3T cornstarch mixture. Return to stovetop, bring to boil and then cook for two mins. Remove from heat and add vanilla. Perfect! Read More

I still can't believe that this recipe is so good yet easy to make. I made cream puffs and tried this filling recipe. Everyone loved them and said they were the best cream puffs they ever had. Read More

I love how quick this is. I had a fairly small cake however and this was a ton of custard!! You end up with about 2 and a half cups of custard. I'd recommend halving the proportions for a more moderate amount. Read More
