Jam Jam Cookies

From the kitchen of Carly

Canadian sandwich cookies with a soft, molasses-and-cinnamon shell holding a generous layer of jam in the middle. Old-school grandmother energy. Perfect with strong tea, batches of two dozen, gone in a day. Pull the cookies when they still look puffy and underdone. They firm up as they cool; overbaked is the cookie killer.

Jam Jam Cookies

Molasses-spiced shortbread cookies with a soft, chewy crumb and a generous jam filling. The baking soda trick gives them height and that desirable puff in the center, while the butter and sugar creaming builds structure without density. These are the cookies that remind you why British and Canadian bakeries know their business: simple dough, perfect timing, and jam doing the heavy lifting.

Ingredients

18 servings

  • 1large egg
  • 1 cupunsalted butter, softened
  • 1 cupgranulated sugar
  • 1/2 cupmolasses (fancy or cooking)
  • 1 tspvanilla extract
  • 2 tspbaking soda
  • 3 tbspwarm water (to dissolve baking soda)
  • 2 tspbaking powder
  • 1 tspground cinnamon
  • 1 tspkosher salt
  • 4 cupsall-purpose flour
  • 2 cupsraspberry, strawberry, or apricot jam

Instructions

  1. Heat the oven to 350°F (180°C). Line two large baking sheets with parchment paper.

  2. In a stand mixer with the paddle attachment (or a large bowl with a hand mixer), cream the softened butter, sugar, and egg together for 2 minutes until pale and fluffy.

  3. Add the molasses and vanilla. Mix until smooth and uniform.

  4. Stir the baking soda into the warm water until dissolved. Add to the mixer. Mix for 1 minute to incorporate.

  5. In a separate bowl, whisk together the flour, baking powder, cinnamon, and salt.

  6. Add the dry mix to the wet in 2 or 3 additions, mixing on low between each, scraping down the bowl as needed. Stop the moment everything is combined; the dough should be soft but easy to shape.

  7. Scoop tablespoon-sized balls of dough. Roll between your palms. Place on the prepared sheets, leaving 2 inches between cookies.

  8. Press each ball flat with the bottom of a floured glass or your moistened palm. Aim for 1/3 inch thick discs.

  9. Bake 10 to 12 minutes, until the edges are set and the centers look puffy but soft. Don't overbake; you want chewy.

  10. Cool the cookies on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.

  11. Once cool, sandwich the cookies: spread 2 teaspoons of jam on the flat side of one cookie, then top with another flat-side-down. Press gently.

  12. Store in an airtight container 4 days at room temperature, or freeze unfilled cookies for 3 months.

Tips from the kitchen

  • Dissolve the baking soda in warm water before adding it to the wet ingredients. This activates it and distributes it evenly; trying to mix it dry will leave bitter pockets and uneven rise.
  • Don't overbake. Pull the cookies when the edges are set but the centers still look slightly underbaked. They'll firm up as they cool and stay chewy instead of turning dry.
  • Press the dough balls flat with the bottom of a floured glass or a moistened palm. This gives you uniform thickness and ensures even baking without the cookies spreading unevenly.
  • Spread jam on the cooled cookie. If the cookies are warm, the jam will melt into the cracks instead of sitting on top as a proper filling.

Variations

  • Lemon curd instead of jam: swap the raspberry or strawberry for lemon curd. The tartness cuts the molasses sweetness and makes these feel more sophisticated.
  • Brown butter base: cook the butter in a saucepan over medium heat until golden and nutty, then let it cool before creaming with sugar. This deepens the flavor without changing the method.
  • Ginger snap twist: add 1 teaspoon of ground ginger and 1/2 teaspoon of ground cloves to the dry ingredients. Keep the cinnamon. Serve with apricot or fig jam for warmth.
  • No baking soda: if you only have baking powder, use 1 tablespoon total and omit the baking soda and water. The cookies will be denser and more shortbread-like, but still good.

Make ahead and storage

Store filled cookies in an airtight container at room temperature for 4 days. Freeze unfilled cookies for up to 3 months, then fill them after thawing. Do not freeze filled cookies, as the jam can weep and the filling will separate.

Substitutions
  • molasses to treacle, golden syrup, or honey. Treacle is the closest substitute (UK staple). Golden syrup and honey both work but make the cookies sweeter; reduce sugar to 3/4 cup.
  • raspberry jam to Nutella, lemon curd, or salted caramel. Nutella takes it in a chocolate direction. Lemon curd makes them brighter; salted caramel makes them rich. All work.
  • all-purpose flour to 1-to-1 gluten-free flour blend. Cookies will be slightly more crumbly. Add 1 tsp xanthan gum if your blend doesn't include it.
