I absolutely love this recipe because the buttery sable cookies paired with the sweet-tart raspberry jam create a nostalgic flavor that reminds me of childhood treats. Plus, there’s something so satisfying about dusting them with powdered sugar and serving them to friends over coffee, making everyday moments feel extra special!

I enjoy preparing Raspberry Jam Filled Sable Sandwiches, or Lunettes De Romans, as they are known in France. They are delicate cookies with a tender dough made from a mix of all-purpose flour, granulated sugar, and salt, and a copious amount of softened, unsalted butter.

The flavor of the finished dough is richer than the simple butter and sugar cookies that inspired it, thanks to a large egg yolk and a mild vanilla flavor. Halfway through the baking process, I remove the cookies from the oven, add a dollop of raspberry jam to the center of each cookie, and return them to the oven to finish baking.

Ingredients

All-Purpose Flour:
Gives organization and carbs; doesn’t have much roughage.

Granulated Sugar:
Makes the cookies sweeter; adds crispiness.

Unsalted Butter:
Provides richness, buttery flavor, and tender texture.

Raspberry Jam:
The sweet, slightly tart flavor contributes a fruitiness and luxurious filling.

Powdered Sugar:
Delicate grain; contributes sweetness and ornamental sprinkles.

Ingredient Quantities

“`html

  • 2 cups all-purpose flour
  • 1/2 cup granulated sugar
  • 1/4 teaspoon salt
  • 1 cup unsalted butter, softened
  • 1 large egg yolk
  • 1 teaspoon vanilla extract
  • 1/2 cup raspberry jam
  • Powdered sugar, for dusting

Instructions

1. In a big mixing bowl, combine well the all-purpose flour, the granulated sugar, and the salt. Whisk them together until they are well mixed.

2. Incorporate the softened unsalted butter into the dry ingredients, mixing until the combination is crumbly and has the appearance of coarse sand.

3. Incorporate the egg yolk and vanilla extract, and mix until a smooth dough is formed. Wrap the dough in plastic wrap and chill for a minimum of 1 hour.

4. Heat your oven to 350°F (175°C) beforehand. Parchment paper two baking sheets.

5. On a surface lightly dusted with flour, roll out the chilled dough to roughly 1/8 inch in thickness. Use a circular cookie cutter to punch out rounds of dough.

6. Use a smaller cutter to punch a hole in the center of half the circles, making them into rings.

7. Set the solid circles on one prepared baking sheet and the rings on another. Bake each batch for about 10-12 minutes or until the edges are lightly golden. Cool completely on a wire rack.

8. Spread approximately 1 teaspoon of raspberry jam onto the sturdy cookies.

9. Generously dust the rings with powdered sugar and then set one on top of each jam-covered cookie to create a sandwich.

10. For a delightful treat, serve the Sable Sandwiches filled with Raspberry Jam alongside tea or coffee.

FAQ

  • Can I use salted butter instead of unsalted?Certainly, but if you are using salted butter, decrease the added salt to a pinch.
  • Can I substitute another type of flour?For the best texture, use all-purpose flour, but you could substitute a gluten-free flour blend in a 1:1 ratio if necessary.
  • What’s the best way to soften butter?Butter should sit at room temperature for 30-60 minutes before you need it. Avoid the temptation to microwave it; that will change its nifty spread-ability.
  • Can I use a different type of jam?Absolutely! Any fruit jam or preserve may be used to customize the flavor.
  • How do I prevent the cookies from spreading too much?To help keep the cookies’ shape, make sure to chill the dough before baking.
  • Is there a vegan version of this recipe?A substitute for egg yolk might work, but the consistency might not be as rich. When using a plant-based butter, you may need to adjust the amount of flour and/or liquid used because the plant-based butter may not have the same water content as traditional butter. In that case, the dough won’t hold together, and the end product will likely have a dense texture.

Substitutions and Variations

A gluten-free alternative to 1 cup of all-purpose flour is obtained by using 1 cup of gluten-free all-purpose flour blend.
1/2 cup granulated sugar can be exchanged for 1/2 cup of coconut sugar to yield a deeper flavor.
1 cup butter, at room temperature can be substituted with 1 cup vegan butter for a dairy-free version.
A vegetarian alternative to 1 large egg yolk is 1 tablespoon of applesauce.
1/2 cup raspberry jam can be replaced with 1/2 cup strawberry or apricot jam to give your recipe a new fruity flavor.

Pro Tips

1. Chill the Dough Well: Ensure the dough is chilled for at least an hour, or even overnight, to enhance its texture and prevent spreading while baking.

2. Prevent Sticking: When rolling out the dough, lightly dust both the surface and your rolling pin with flour to prevent sticking. Alternatively, you can roll the dough between two sheets of parchment paper.

3. Uniform Cookie Thickness: Use guide sticks alongside your dough while rolling to ensure even thickness, which will help the cookies bake uniformly.

4. Avoid Overworking the Dough: Mix the ingredients just until combined to prevent the dough from becoming tough. Overworking can lead to tough cookies.

5. Seal the Jam: For an even spread and reduced chance of leaking, use a piping bag or small spoon to distribute the raspberry jam evenly on each cookie.
