Lemon Poppy Seed Sandwich Cookies

Poppy seed filling is seldom used in American cookies.  In fact, the only time I see it with regularity is in Hamantashen, and even then, I’d never heard of someone making the poppy seed filling from scratch.  I decided to experiment with from-scratch filling in these lemon poppy seed sandwich cookies.  While you could use lemon curd as a filling for these little butter cookies dotted with poppy seeds (I wouldn’t fault you for making that splendid choice), filling the cookies with a poppy seed filling gives them more of a winter warmth.

Poppy seed filling, you’ll find, isn’t tough to make.  Once you have it on hand, you can use any extra filling as a spread on toast or crackers.

To make poppy seed filling that is smooth (not gritty and crunchy), you’ll need ground poppy seeds.

You can buy ground poppy seeds, but I’ve never seen them in a store near me.  Have you?

Alternatively, you can buy regular poppy seeds (these should be easy to find with the spices at your local grocery store) and use a poppy seed grinder to grind them.  But, that is an expensive purchase which doesn’t have much application unless you are always making desserts with poppy seeds.

I’d read that you can use a coffee/spice grinder to grind poppy seeds, but I wasn’t able to get my poppy seeds nearly fine enough with mine.

Vitamix CIA Professional Series Blender, Platinum

I had the most success at poppy seed grinding using my Vitamix blender.  After just a few seconds in there, the poppy seeds were smooth and ground.

If all else fails, you can use pre-made poppyseed filling.  I highly encourage you to first give making your own poppy seed filling a shot with my recipe below.

European Cookies for Every Occasion

I was inspired to make this lemon poppy seed sandwich cookie recipe after seeing a recipe for poppy seed stars in this book.  My cookie recipe is only slightly adapted from that recipe, however the filling recipe is my own; the lemon star recipe in the book is filled with jam.  I also want to mention that this is one of the few cookie books I read during this project that has step-by-step and completed cookie photos for every cookie.  If you like to be hand-held through the cookie-making process, you will love this one!

Lemon Poppy Seed Sandwich Cookies

Servings 24 cookies


Cookie Ingredients

  • 1/2 teaspoon baking powder
  • 2 tablespoons lemon juice
  • 1/4 teaspoon lemon extract leave this off if you don't like a strong lemon flavor
  • 1 3/4 cups all-purpose flour
  • 1/2 cup + 2 tablespoons unsalted butter room temperature
  • 1 egg yolk

  • 1/4 cup poppy seeds

Poppy Seed Filling Ingredients

  • 1 cup milk
  • 1 1/2 cups ground poppy seeds
  • 1/2 cup sugar
  • 1/4 cup honey
  • 2 tablespoons unsalted butter
  • 1 teaspoon vanilla


Cookie Instructions

  1. In a medium-sized mixing bowl, dissolve baking powder in lemon juice. It's fun to listen to it hiss and to watch it bubble.
  2. Add lemon extract, flour, butter, egg yolk, sugar, and salt. Knead the batter together either with your hands or using the dough hook on a stand mixer.
  3. Mix in the poppy seeds and form the dough into a small loaf.
  4. Wrap in plastic and refrigerate for one hour.

Poppy Seed Filling Instructions

  1. In a medium-sized pot on low heat, bring milk to a simmer and add poppy seeds, sugar, and honey.
  2. Simmer for 15 minutes, stirring frequently until the poppy seeds absorb the milk and you have a thick paste.
  3. Remove from heat and stir in butter and vanilla.
  4. Place the whole mixture in the blender and blend until smooth.
  5. Refrigerate for about 20 minutes to let the filling firm up.

Assembly and Baking Instructions

  1. Preheat oven to 350 F.
  2. Lightly flour a work surface and roll the dough to 1/8" thick.
  3. Cut out 2 1/2" flowers or stars or whatever other shape you might like as long as there are two of each kind.
  4. Use a cookie cutter or a fat straw to cut a one inch hole in the centers of half of the cookies.
  5. Place cookies on a parchment-lined cookie sheet.
  6. Bake for 10 minutes or until the edges just begin to brown.
  7. Cool on a cooling rack.
  8. Spread poppy seed filling on all of the cookies without holes.
  9. Top with matching cookies to create sandwiches.

Recipe Notes

If you are able to find ground poppy seeds or have a poppy seed grinder and can grind your own, use them in this recipe and skip the blender step.

Something I learned about poppy seeds while making these cookies is that they go rancid really quickly - they have a very high oil content. If you have any extra poppy seeds from this project, be sure to store them in the freezer.
