Preheat oven to 350 degrees F. Insert cupcake liners into a cupcake tin. In a medium bowl, whisk together the flour, baking powder and salt. In a measuring cup, measure out the buttermilk and whisk in the vanilla.
To the bowl of a stand-up mixer, with the paddle attachment, add the butter, sugar and honey. Cream together until light and fluffy, about 2 minutes. Crack in the eggs and mix until combined. Add the flour in a few batches, alternating with the buttermilk mixture, until combined.
Fill each cupcake tin with two tablespoons of batter, about halfway. Nestle the cutout hearts in the center of each cupcake tin, facing them all the same way.
Transfer to the oven to bake for 15 to 20 minutes, or until a toothpick inserted into the white cake comes out clean. Cool in the pans on the wire rack for about 5 minutes.
What’s good about these cupcakes that at this point, you can see where you need to cut in order for them to see the heart in the center.
