Homemade Chocolate-Banana Pudding

1 . Stage

Combine milk and chocolate in the top of a double boiler over simmering water. Stir frequently, scraping down the sides with a rubber spatula to avoid scorching, until chocolate is melted and mixture is hot, about 5 minutes.

2 . Stage

Mix sugar, flour, and salt together in a bowl. Add some of the hot liquid to the dry ingredients; mix well. Pour dry ingredients into the double boiler and stir well. Cover and cook over a rolling boil, stirring often, until thickened, about 15 minutes.

3 . Stage

Pour some of the hot mixture into the beaten egg yolks, whisking quickly to avoid scrambling the eggs. Pour the mixture back into the double boiler and whisk to combine. Whisk in butter and vanilla.

4 . Stage

Line the bottom of a serving bowl with wafer cookies. Pour in some of the pudding to cover and top with sliced bananas. Repeat layers until all of the pudding is gone, ending with bananas on top.
