Instructions

  1. Combine flour, sugar, cornstarch, and salt in a small saucepan.
  2. Add milk gradually.
  3. Cook, stirring, over low heat until thickened. (Do not rush this stage as it gets rid of the raw flour flavor).
  4. Blend a little of the hot mixture into egg yolks.
  5. Stir yolks into saucepan. Cook 1 minute. Remove from heat.
  6. Add vanilla and butter. Cool.
  7. When ready to serve fold in diced bananas. Place a small amount of filling on each crepe and roll.
