Double-Shot Mocha Cupcakes

I don't request dessert recipes often, but one bite of these cupcakes and I was hooked. Thankfully, it was a love and olive oil recipe, so I didn't even have to wait impatiently for someone to send me the recipe! Even more thankfully, I have a couple of leftover mini-cupcakes sitting in my fridge right now.

Double-Shot Mocha Cupcakes (from Love and Olive Oil)

Ingredients
1 cup coconut milk
1 tablespoon instant espresso powder or 1/2 ground coffee
1/3 cup canola oil
1 teaspoon vanilla extract
3/4 cup sugar
1 cup all-purpose flour
1/3 cup cocoa powder
3/4 teaspoon baking soda
1/2 teaspoon baking powder
1/4 teaspoon salt
Frosting:
1/4 cup cocoa powder
2 cups powdered sugar
1/2 cup butter
1/8 teaspoon salt
3 tablespoons brewed coffee (cooled)
1/2 teaspoon vanilla
Directions:

1. Preheat oven to 350 degrees F. Line muffin pan with paper liners.
2. In a microwave safe bowl, heat coconut milk until hot (but not boiling). Stir in espresso powder. If you don't have espresso powder, put coffee grounds into a fine sieve. Pour coconut milk over grounds and allow to seep through. You will end up with a few grounds in your milk this way, but it won't affect the final product.
3. Whisk sugar, oil, and vanilla extract in to coffee mixture.
4. In a separate bowl, sift together the flour, cocoa powder, baking soda, baking powder, and salt.
5. Add to wet ingredients and beat until no lumps remain (or very few remain).
6. Pour into liners, filling each with a scant 1/4 cup of batter. Bake 18-22 minutes, until a toothpick inserted into the center comes out clean. Transfer to a cooling rack and let cool completely.
7. For frosting, sift together powdered sugar, cocoa.
8. Cream butter and add to sugar mixture slowly.
9. Add salt, and coffee. Beat 2 minutes.
10. Add vanilla and beat until light and fluffy. Spread or pipe onto cooled cupcakes.
