- 3 cups all-purpose flour
- 1 3/4 teaspoons baking powder
- 1 1/4 teaspoons salt
- 1 1/3 cups milk at room temperature
- 1 1/2 teaspoons lemon extract
- 1 1/4 teaspoons vanilla extract
- 3/4 teaspoon orange extract
- 1 1/8 cups unsalted butter at room temperature
- 2 cups white sugar
- 4 eggs at room temperature
- 1/2 cup vegetable shortening
- 1/2 cup butter at room temperature
- 4 cups confectioners' sugar
- 2 tablespoons milk at room temperature
- 1 teaspoon clear vanilla extract
- Place a rack into the lower third of oven.
- Preheat oven to 325 degrees F (165 degrees C).
- Grease and flour a cake mold pan (such as a bunny cake or train cake mold) using vegetable shortening.
- Sift flour, baking powder, and salt in a bowl.
- Mix 1 1/3 cup milk, lemon extract, 1 1/4 teaspoons vanilla extract, and orange extract in a separate bowl.
- Beat unsalted butter in a large mixing bowl with an electric mixer on medium speed until butter is creamy and smooth, 1 to 2 minutes. Beat in white sugar and continue beating until the mixture is light and fluffy, about 5 more minutes. Scrape the sides of the bowl occasionally.
- Beat in eggs, one at a time, beating each egg in thoroughly before adding the next.
- Reduce mixer speed to low and beat in flour mixture in several additions, alternating with milk mixture; begin and end with flour mixture. Do not overbeat. Scrape bowl occasionally.
- Pour batter evenly into prepared cake pan.
- Bake in the preheated oven until lightly browned and a toothpick inserted into the middle of the cake comes out clean, 30 to 45 minutes.
- Place cake in pan on a wire rack and allow to cool for 15 minutes before inverting pan to remove cake. Allow cake to completely cool on wire rack, 3 to 4 hours.
- Beat vegetable shortening, 1/2 cup butter, confectioners' sugar, 2 tablespoons milk, and 1 teaspoon clear vanilla extract in a bowl until frosting is smooth and creamy.
- Pack the frosting into a heavy resealable plastic bag; force the frosting into one corner of the bag. Clip a small corner off the plastic bag, seal the bag, and pipe the frosting onto the cooled cake in desired pattern.
