Heat oven to 375°F. Line a standard muffin pan with liners or lightly grease it.
Cut pouch open at top corner. Squeeze the batter into a bowl, then gently fold in the raspberries.
Scoop the batter into each cup, filling them 2/3's full.
Bake for 18-23 minutes or until a toothpick inserted into the center comes out clean. If you’re using frozen raspberries, bake time might be slightly longer.
While the cupcakes are baking, prepare the frosting.
Frosting: Using a hand or stand mixer, beat the butter until smooth and creamy. On low-speed, gradually add half of the powdered sugar, mixing until well combined. Then, add the remaining powdered sugar, continuing to mix until fully incorporated and smooth.
Add the coconut milk, along with the vanilla and coconut extracts, then mix on medium-speed until the frosting becomes light and fluffy.
