Prep Work
Before diving into the baking, let’s ensure our workspace and ingredients are perfectly prepped. Proper Prep Work sets the foundation for crafting authentic Trefoil Cookies with that iconic buttery crunch and luscious caramel filling.
Preparing the Dough
To prepare the buttery shortbread dough, we start by bringing the unsalted butter to room temperature for easy creaming. In a large mixing bowl, we combine:
- 1 cup (227 g) unsalted butter, softened
- ½ cup (100 g) granulated sugar
- 1 teaspoon pure vanilla extract
- 2 cups (240 g) all-purpose flour
- ¼ teaspoon salt
Using an electric mixer, we cream the butter and sugar together until light and fluffy, about 2-3 minutes. Then, we blend in the vanilla extract.
Next, we gradually add the flour and salt, mixing on low speed to form a smooth dough. It’s vital not to overmix — stopping as soon as the dough clumps together ensures a tender texture.
We then transfer the dough onto a lightly floured surface and gently knead it just to bring it together. This step maintains the delicate crumb that makes Trefoils special.
Chilling the Dough
Chilling the Dough is a key step to prevent spreading and help maintain the cookie’s distinctive shape. We flatten the dough into a disk about 1 inch thick and wrap it tightly in plastic wrap.
Then, we refrigerate for at least 1 hour. This cooling period firms up the butter, making the dough easier to roll and cut precisely with the Trefoil cookie cutter.
| Chilling Time | Purpose |
|---|---|
| 1 hour+ | Firms dough for easy rolling & cutting |
| Overnight | Enhances flavor development |
Once chilled, the dough is ready to be rolled out evenly for cutting into the iconic trefoil shapes, making our baking process smooth and our final cookies perfectly crisp and tender.
Instructions
Follow these clear steps to transform our Trefoil Cookie dough into beautiful, buttery treats that capture the classic taste and delicate texture. Precision and care during each phase ensure perfectly crisp, tender shortbread cookies every time.
Rolling and Cutting the Dough
- Lightly flour your work surface to prevent sticking.
- Remove the chilled dough from the refrigerator and let it sit for 5 minutes for easier rolling.
- Roll the dough to a uniform thickness of 1/4 inch (6 mm) using a rolling pin.
- Dust the rolling pin lightly with flour to avoid dough adhesion.
- Use the Trefoil cookie cutter to press firmly into the dough, cutting out shapes cleanly without dragging.
- Re-roll any leftover dough once or twice, but avoid overworking it to maintain a tender crumb.
- Transfer cut dough shapes onto a baking sheet lined with parchment paper or a silicone baking mat, spacing cookies at least 1 inch apart.
Shaping the Trefoil Cookies
- Inspect each cut cookie to ensure the iconic trefoil shape is well-defined.
- Use a small knife or toothpick to gently refine details if necessary, especially the trefoil indentations.
- For a polished look, gently smooth any rough edges with your fingers.
- Chill the shaped cookies again on the baking sheet for 15 to 20 minutes. This step helps prevent spreading and maintains the crisp outline when baking.
- While chilling, preheat your oven to 325°F (163°C) for perfect baking temperature control.
Baking the Cookies
| Step | Detail |
|---|---|
| Oven Temperature | Preheat to 325°F (163°C) |
| Baking Time | Bake for 15 to 18 minutes |
| Cookie Position | Place baking sheet in the center rack |
| Visual Cue | Edges should be lightly golden |
| Cooling Time | Cool on a rack for 10 minutes before filling |
- Slide your prepared baking sheet onto the center rack for even heat circulation.
- Bake the cookies until the edges are just turning golden, preserving the soft crumb inside. Avoid overbaking for the best tender texture.
- Remove cookies from the oven and immediately transfer to a wire cooling rack.
- Let cookies cool completely before adding caramel filling or storing to maintain texture integrity.
Filling and Assembly
Creating the perfect Trefoil Cookie experience hinges on a smooth caramel filling and careful assembly. Let’s delve into the steps to make our cookies irresistibly rich and beautifully finished.
Preparing the Filling
To capture that classic Trefoil Cookie flavor, our caramel filling blends sweetened condensed milk, butter, caramel sauce, and a pinch of sea salt flakes. Here’s how we prepare it:
- Combine Ingredients
In a small saucepan, mix:
- 1/2 cup caramel sauce
- 1/4 cup sweetened condensed milk
- 2 tablespoons unsalted butter
- A pinch of sea salt flakes
- Warm and Stir
Heat the mixture over low-medium heat. Stir continuously with a spatula or wooden spoon until the butter melts and the filling is smooth and glossy.
- Cool to Spreadable Consistency
Remove from heat and allow the filling to cool for about 10-15 minutes. It should thicken but remain spreadable.
Pro Tip: Stirring constantly prevents burning and ensures the filling maintains a luscious, creamy texture essential for layering the cookies.
Assembling the Cookies
With our cookies fully baked and cooled, and our filling at the perfect consistency, it’s time to assemble:
| Step Number | Action | Details |
|---|---|---|
| 1 | Select cookie pairs | Match cookies by size and shape |
| 2 | Spread filling | Use about 1 tablespoon on one cookie’s flat side |
| 3 | Sandwich | Gently press the paired cookie on top |
| 4 | Chill or rest (optional) | Let cookies rest 15-20 minutes for filling to set |
Detailed Steps:
- Using a butter knife or small offset spatula, spread an even layer of filling on the flat side of one cookie.
- Sandwich it with its matching cookie, pressing gently to avoid squeezing out too much caramel.
- Arrange assembled cookies on a baking sheet lined with parchment paper.
- For best texture and handling, chill the cookies briefly in the refrigerator to allow the filling to firm up.
“The key to perfect Trefoil Cookies is balancing the buttery shortbread’s crumbly texture with the luscious smooth caramel.” We recommend careful spreading and pairing to honor this classic harmony.
This filling and assembly step elevates our homemade Trefoil Cookies into the iconic treat we all love.
