  • 1/2 tsp salt
  • 1 Large Egg at room temperature
  • 2 3/4 Cups AP Flour (340g)
  • 1/2 tsp Baking powder
  • 1/2 tsp Vanilla Extract

Poppy Seed Filling

  • 1 Cup Whole poppy seeds (120g)
  • 1/2 Cup Powdered sugar (60g)
  • 1 Tablespoon Flour
  • 1 Large Egg at room temperature
  • 1/4 Cup Unsalted softened butter (55g)
  • 1 teaspoon Vanilla extract

Crumbs Topping

  • 2 TBS Sugar (25g)
  • 2 TBS Butter ir shortening soften (28g)
  • 1 1/2 tsp Honey
  • 1/3 Cup AP flour (40g)

Instructions

  • In a food processor, process the sugar and butter until incorporated.
  • Mix the flour, salt, and baking powder in a bowl then add it to the food processor followed by the egg and vanilla extract.
  • Pulse the mixture until a dough is formed.
  • Wrap the dough with plastic wrap and refrigerate for a minimum of 1 hour. Remove from the refrigerator 10-15 minutes before baking.
  • Preheat oven to 375F Line an 8x8-inch  baking pan with parchment paper and grease the sides.
  • Roll the dough and flatten it evenly inside the baking pan. Using a fork prick it thoroughly and bake it for 15 minutes. Remove from the oven and set aside to cool.

Make The Toppings

  • Place the poppy seeds filling ingredients in a food processor and process until a smooth paste is formed.
  • Use a fork to mix all of the crumbs topping together until you have a lumpy mixture.

Assemble and Bake

  • Preheat your oven to 350F (180C)
  • Evenly spread the filling and sprinkle the crumbs on-top.
  • Bake for 30-35 minutes until the streusel is slightly golden brown. Allow the bars to completely cool before slicing.

Notes

  • Use a store-bough filling if available to you. (1-2 cups depending how thick you wish your filling to be)
  • For a thicker layer of filling, double the filling layer.
  • Make sure the ingredients are at room temperature, and always use a kitchen scale to measure the ingredients.
  • Brush the topping with beaten egg yolks for a more vibrant topping color.
  • The cake is ready when the topping is golden brown, and the edges of the crust should be set. If unsure, insert a toothpick into the filling; it should come out mostly clean.
  • You can use ground poppy seeds instead of whole poppy seeds but note it will enhances the bitterness of the seeds.
  • Add 1/2 cup of fine ground almonds to the flour mixture for an extra nutty flavor.
  • This recipe can be used to make one 8x8-inch cake, or 9x9-inch cake, and can be sliced into 12-16 pieces. You can also use an8, or 9 inch springform pan.  Another option is to se a 9x13-inch baking pan, it will be thinner and I recommend doubling the filling recipe. Make sure the pans are at least 2.5 heigh.
