Add all wet ingredients, including strawberries, in a large mixing bowl for 2 minutes until blended well.
Combine the wet and dry ingredients together and mix well.
Place cupcake liners in the cupcake pan and fill each cupcake liner ¾ full with cake mixture.
Bake in preheated oven until a toothpick inserted the center of a cupcake comes out clean, about 21 minutes.

Once cooled, poke holes in the cupcakes and brush tequila over the top using a BBQ sauce brush, or you can dip the top of the cupcake into a bowl of tequila.

Set on low speed and mix, increasing to medium speed slowly.
