Preheat the oven to 350 degrees and line a cupcake pan with paper liners.
Combine flour and baking soda in a bowl, stir, and set aside.
In a medium sized bowl, cream butter and sugar on medium speed until completely incorporated.
Add eggs and vanilla extract, and mix well.
Add whiskey and flour mixture. Mix on low speed until just combined.
Add lemon juice and mix until completely incorporated.
Spoon cupcake batter into the prepared pan, filling paper liners about 2/3 full.
Bake for 15-17 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
Let cupcakes cool in the pan for five minutes, then move to a wire rack to cool completely. (Let cupcakes cool completely before frosting.)
