Equipment
- Mixing bowl
- Hand mixer or stand mixer
- Microplane or fine zester
- Rubber spatula
- plastic wrap
- Sharp knife
- Baking sheet
- Parchment paper
- Cooling rack
Ingredients
- 1 cup 226g unsalted butter, softened but cool
- 3/4 cup 90g powdered sugar
- 1 teaspoon finely grated grapefruit zest
- 2 teaspoons vanilla bean paste or vanilla extract
- 1 large egg yolk
- 1 3/4 cups 220g all-purpose flour
- 1/4 cup 30g cornstarch
- 1/2 teaspoon fine salt
Optional Sugar Coating
- 1/4 cup granulated sugar
Instructions
- In a small bowl, rub the grapefruit zest into the powdered sugar until fragrant and slightly moist.
- In a large bowl, mix butter and grapefruit sugar until smooth and creamy. Do not whip airy.
- Add egg yolk and vanilla. Mix until fully combined and silky.
- Add flour, cornstarch, and salt. Mix just until a soft dough forms. Do not overmix.
- Divide dough in half and shape into two logs about 2 inches thick. Wrap tightly in plastic wrap.
- Chill dough for 1½ hours until firm.
- Preheat oven to 325°F (163°C). Line baking sheets with parchment paper.
- Roll logs in granulated sugar if desired. Slice into 1/4-inch thick cookies.
- Arrange cookies 1 inch apart on prepared baking sheet.
- Bake for 11–13 minutes until bottoms are lightly golden and tops remain pale.
- Cool on pan for 5 minutes, then transfer to a wire rack to cool completely.
Notes
- Use finely grated grapefruit zest only. Avoid grapefruit juice, which can make sablé cookies bitter and affect texture.
- Rub the grapefruit zest into the powdered sugar first to release citrus oils and evenly distribute flavor throughout the dough.
- Use powdered sugar instead of granulated sugar for a tender, melt-in-your-mouth sablé cookie texture.
- Cornstarch helps create the classic delicate French sablé crumb and keeps cookies soft and buttery.
- Chill the dough thoroughly before slicing to prevent spreading and maintain clean, round cookie edges.
- Slice cookies evenly at about 1/4 inch thick for consistent baking and elegant presentation.
- Do not overbake. Sablé cookies should remain pale on top with lightly golden bottoms.
- Vanilla bean paste gives the best flavor, but pure vanilla extract works well too.
- For stronger citrus flavor, add an extra light sprinkle of grapefruit zest to the sugar coating before rolling.
- These grapefruit vanilla sablé cookies firm up as they cool and develop their best texture after resting.
- Store cookies in an airtight container to preserve their delicate buttery texture and citrus aroma.
