I have a Crumbl problem, and I’m not seeking help.
These lemon poppy seed cookies are hands down my favorite thing on their rotation. I have tried to recreate the recipe at home SEVERAL times, and the filling was always the issue. It would melt out, or spread weird, or just not have that bright, tart punch the real ones have.
Freezing the lemon curd into little pucks first? Absolute game changer. The cookie wraps around it like a blanket and bakes up soft and thick, and when you bite in, you get that cold-blasted lemon smack right in the center.
The glaze is buttery and tangy and has just enough poppy seed crunch to remind you it’s there. I ate three before they were fully cool. No regrets.
Why You Must Freeze the Lemon Curd
- FROZEN CURD WON’T LEAK: Soft curd melts fast and escapes through dough seams, pooling on your pan and ruining that clean cookie shape
- DEFINED CENTER EVERY TIME: The solid disc holds its form while the dough bakes around it…. giving you a perfect pocket of tart filling
- EASIER TO WRAP: A frozen center is simple to encase in sticky dough (try it with soft curd and you’ll have a sticky mess on your hands)
How to Wrap the Dough Without Leaks
Flatten each dough portion into a 1/4 inch disk (thinner edges seal best!). Drop ONE frozen curd mound dead center, then pull the dough up and around it like a tiny blanket. Pinch every seam shut, because cracks equal leaks…. and leaks equal sadness.
Flip seam-side down and press gently with your palm to 1/2 inch thick. Keep that curd fully buried, no peeking allowed!
Storing & Keeping Them Fresh
- REFRIGERATE due to the egg-based lemon curd filling…. airtight container, 4-5 days max.
- BRING TO ROOM TEMP before serving (15 minutes on the counter restores that soft, tender bite).
- FREEZE individually wrapped in plastic wrap, then foil, up to 2 months!
- THAW overnight in the fridge so the glaze stays intact.
- NEVER leave them uncovered… the glaze hardens fast and your cookies go stale quick.

Ingredients
For the filling:
- 3/4 cup lemon curd (I use Dickinson’s for a thick, tart consistency)
For the dough:
- 8 tbsp butter (room temperature, about 70°F)
- 1/2 cup powdered sugar
- 1/4 cup sugar
- 1 egg
- 1 egg yolk
- 1.5 tbsp lemon juice
- 1.5 tsp lemon flavoring (I prefer Watkins lemon extract for a more natural taste)
- 1/2 tbsp lemon zest (finely grated, avoiding the bitter white pith)
- 2 cups flour (I always use King Arthur all-purpose flour)
- 1/2 tsp baking powder
- 1/4 tsp salt
- 1 tbsp poppy seeds
For the glaze:
- 5 tbsp powdered sugar (sifted to remove lumps)
- 1 tbsp lemon juice
- 1/2 tsp lemon zest
- 2 tbsp butter
- 1/2 tsp poppy seeds
- pinch of salt
Step 1: Freeze the Curd Portions
- 3/4 cup lemon curd
Spoon 8 portions of lemon curd onto a parchment-lined baking sheet, spacing them about 2 inches apart.
Freeze for 1-2 hours until solid—this prevents the curd from leaking out during baking and gives you a defined filling center.
While the curd freezes, you’ll have time to prepare all your other ingredients.
Step 2: Prep Dry Ingredients and Lemon
- 2 cups flour
- 1/2 tsp baking powder
- 1/4 tsp salt
- 1 tbsp poppy seeds
- 1/2 tbsp lemon zest
- 1.5 tbsp lemon juice
While the curd freezes, preheat your oven to 350°F and prepare your dry ingredients: whisk together the flour, baking powder, salt, and 1 tablespoon poppy seeds in a small bowl and set aside.
Finely zest the lemon (avoiding the white pith) and juice it to get your 1.5 tablespoons lemon juice.
Have all ingredients measured and ready before you start mixing the dough—this ensures smooth, efficient mixing and prevents overmixing.
Step 3: Mix the Cookie Dough
- 8 tbsp butter
- 1/2 cup powdered sugar
- 1/4 cup sugar
- 1 egg
- 1 egg yolk
- 1.5 tsp lemon flavoring
- dry ingredient mixture from Step 2
In a mixing bowl, cream together the room-temperature butter, powdered sugar, and sugar until light and fluffy, about 2-3 minutes.
Add the egg, egg yolk, lemon juice, lemon extract, and lemon zest from Step 2, beating until well combined.
Gently fold in the dry ingredient mixture from Step 2 until just combined—don’t overmix, as this keeps the cookies tender.
The dough should come together quickly and be slightly sticky but workable.
Step 4: Assemble and Stuff the Dough
- dough from Step 3
- frozen lemon curd from Step 1
Divide the dough from Step 3 into 8 equal portions and gently flatten each into a thin disk about 1/4 inch thick.
Place a frozen lemon curd center from Step 1 in the middle of each disk, then wrap the dough around it and gently flatten the whole cookie to about 1/2 inch thickness.
I like to use my palms to flatten them evenly, rotating the cookie as I press—this creates uniform baking and prevents lumps of dough.
Space them 2 inches apart on a parchment-lined baking sheet.
Step 5: Bake Until Softly Set
Bake the cookies at 350°F for 12-13 minutes, until the edges are set and just lightly golden but the centers still look slightly underbaked.
The cookies will continue to cook slightly after removal and should have a soft, tender crumb.
Let them cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before glazing.
Step 6: Glaze and Garnish
- 2 tbsp butter
- 5 tbsp powdered sugar
- 1 tbsp lemon juice
- 1/2 tsp lemon zest
- 1/2 tsp poppy seeds
- pinch of salt
- cooled cookies from Step 5
While the cookies cool, make the glaze: melt the 2 tablespoons butter in a small saucepan over medium heat, then add the sifted powdered sugar, 1 tablespoon lemon juice, and 1/2 teaspoon lemon zest.
Stir constantly until the mixture simmers and becomes smooth, about 2-3 minutes.
Remove from heat and stir in the 1/2 teaspoon poppy seeds and pinch of salt.
Once the cookies have cooled completely, use a pastry brush or the back of a spoon to brush or drizzle the warm glaze generously over each cookie.
I find that applying the glaze while it’s still warm gives the best coverage and shine—let the glaze set for 15-20 minutes before serving.
