Ingredients
For the Lemon Cookies
- 2 ½ cups cake flour (do not substitute)
- 1 tbsp cornstarch
- 1 tsp baking powder
- ½ tsp salt
- ½ cup granulated sugar
- 2 tsp lemon zest
- ¾ cup unsalted butter (room temperature)
- ¼ cup vegetable oil
- 1 cup powdered sugar
- 1 large egg (room temperature)
- 2 tbsp lemon juice
For the Blueberry Buttercream Frosting
- 1 cup unsalted butter (room temperature)
- 2 ½ cups powdered sugar
- 1 oz freeze-dried blueberries
- ¼ cup heavy cream
- 2 tsp vanilla extract
- ¼ tsp salt
- ¼ cup freeze-dried blueberries (finely chopped)
- 2 tsp lemon zest
Instructions
- Preheat Oven: Preheat your oven to 350℉ (177℃). Line baking sheet pans with silicone baking mats or parchment paper to prevent sticking and ensure even baking.
- Mix Dry Ingredients: In a medium bowl, whisk together the cake flour, cornstarch, baking powder, and salt. Set this dry mixture aside for later incorporation.
- Prepare Lemon Sugar: In a small bowl, combine the granulated sugar with the lemon zest. Massage the mixture to release natural lemon oils to boost the lemon flavor in your cookies. Set aside.
- Cream Wet Ingredients: Using a stand mixer with a paddle attachment or a hand mixer in a large bowl, cream together the unsalted butter, vegetable oil, powdered sugar, and the lemon-infused granulated sugar until the mixture is smooth and creamy.
- Add Egg and Lemon Juice: Beat in the egg and lemon juice until fully incorporated and the mixture remains smooth.
- Combine Dry and Wet Mixtures: Gradually add the dry flour mixture to the wet ingredients, mixing on low speed until a soft cookie dough forms.
- Portion Dough and Bake: Use a large cookie scoop (about 3 tablespoons) to portion the dough onto the prepared baking sheets, spacing them to allow for spreading. Bake for approximately 12 minutes, or until the cookies puff up in the center and the edges remain pale.
- Cool Cookies: Remove the cookies from the oven, cool on the baking sheet for 1 minute, then transfer to a wire rack to cool completely before frosting.
- Prepare Buttercream Base: In a clean bowl, cream the unsalted butter with a paddle attachment or electric hand mixer for about 5 minutes until it becomes light and creamy.
- Add Powdered Sugar: Add half of the powdered sugar and mix on the lowest speed until fully combined. Then add the remaining powdered sugar and continue mixing on low speed until thoroughly incorporated.
- Add Blueberry Powder: Grind the freeze-dried blueberries in a food processor into a fine powder. Incorporate this powder into the butter mixture on low speed until evenly mixed.
- Finish Buttercream: Add heavy cream, vanilla extract, and salt to the mixture. Mix on low speed until fully combined. Occasionally scrape down the sides and bottom of the bowl to ensure even mixing. Increase the mixer speed to medium and whip for 2-3 minutes until smooth and creamy. Reduce speed to low and mix further for several minutes to remove air bubbles.
- Frost Cookies: Fill a piping bag fitted with a Wilton 1A tip with the blueberry frosting. Pipe a swirl of frosting onto each cooled cookie. Use an offset spatula to spread frost evenly if desired.
- Decorate: Garnish the frosted cookies with finely chopped freeze-dried blueberries and sprinkle lemon zest over the top for added flavor and a beautiful presentation.
Notes
- Use cake flour for a tender texture; substituting with all-purpose flour may change the cookie's softness.
- Massage lemon zest with granulated sugar to maximize lemon aroma and flavor infusion.
- Room temperature ingredients, especially butter and egg, ensure smoother mixing and better cookie texture.
- Watch baking time carefully to avoid browning edges; cookies should remain pale.
- Freeze-dried blueberries add intense flavor without extra moisture; ensure to finely powder them for smooth buttercream.
- Use a piping bag for an elegant frosting swirl or spread with an offset spatula for a rustic look.
- These cookies can be stored in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
