This is my mom's recipe that she uses when making banana pudding. I'm definitely a fan of banana pudding with homemade pudding and a meringue topping. You can also make this with Splenda and it turns out great.
2c sugar or Splenda
4 egg yolks
Blend sugar & cornstarch. Beat in egg yolks then gradually add milk. Microwave 2 mins at a time, stirring in between until mixture becomes thick. This takes about 10 mins total cook time. Add butter and vanilla.
