Ingredients
Method
For the cupcakes
- Preheat the oven at 350° F.
- In a big bowl, sift the flour, corn starch, baking powder, baking soda and salt together. Mix and set aside.
- In a different big bowl, using a hand mixer, cream together the butter, oil and sugar for 2 minutes until you get a light and fluffy mixture.
- Add in the eggs one at a time, beating after each addition, then beat in the vanilla extract and the vanilla bean seeds and beat for another 3 minutes. The mixture must turn really fluffy.
- Incorporate the dry ingredients in three separte additions, alternating with the buttermilk, starting and finishing with the dry ingredients (once you´re done with the last dry ingredients addition is important not to beat too much, just until the mixture is well incorporated).
- Distribute the batter filling a cupcake pan (already prepared with cupcake liners) about 3/4 each.
- Bake at 350°F for 22 min. aprox. or until a wooden stick comes out clean when inserted.
- Put the dulce de leche in a pastry bag with a small piping tip. Once the cupcakes are cool, take out a small piece of each using a knife and fill them with dulce de leche, then put the small pieces of cake back in their places.
For the frosting:
- In a big bowl, with a hand mixer beat the butter and cream cheese together until soft.
- Add in the confectioners sugar and salt (both previously sifted) then the vanilla extract and the vanilla bean seeds and continue beating until the mixture lightens in color.
- Beat in the milk and keep on beating until you get a fluffy frosting that´s almost white.
- Decorate the cupcakes with the frosting however you like.
