My 2-ingredient homemade poppyseed filling is simple to make and versatile to use in your sweet breads, rolls, and pastries. I use this filling in my classic poppyseed hamantaschen which is a sweet traditionally served to celebrate Purim. This filling is lightly sweet, slightly nutty, and smooth with a delicate crunch that you expect from poppy seeds.
Add the poppy seeds to a food processor and process until the seeds are ground soft and powdery, which takes about 1 minute. (You can also do this in a coffee or spice grinder in small batches.)
2 cups poppy seeds
In the meantime, warm the sweetened condensed milk in a saucepan until the it becomes thinner and easier to stir.
1 cup sweetened condensed milk
Add the poppy seeds to the warmed sweetened condensed milk and continue to heat for 10 minutes, stirring constantly. Then, cover and refrigerate. The filling will set up and thicken as it chills.
