Citrus lovers have got to try these orange cupcakes with orange buttercream! Made with fresh orange juice and orange zest, these orange cupcakes are bursting with flavor.
Preheat the oven to 350°F and line one cupcake tin with liners. Set aside.
Using a hand mixer or stand mixer with the paddle attachment, beat the butter and oil together until combined. Add in the eggs and vanilla extract.
Mix in the granulated sugar and orange zest.
Add in flour, cornstarch, salt, and baking powder to a separate bowl and whisk together.
Alternate slowly adding in the milk, orange juice, and the dry ingredients. Mix until combined.
Add the cupcake batter to the cupcake tin, filling each cavity ⅔ full. Bake for 13-16 minutes, or until a toothpick inserted in the middle of the cupcakes comes out clean.
Let the cupcakes cool in the pan for 10-15 minutes. While they cool, make the buttercream.
Add in the vanilla extract and ½ cup powdered sugar and mix again. Slowly add in the rest of the powdered sugar, up to 2½ cups. If the buttercream is too thin, add more powdered sugar until desired consistency is reached.If the buttercream is too thick, add in orange juice 1 tablespoon at a time to thin it out to the consistency you want.
Once the cupcakes have cooled completely, frost, decorate as desired, and enjoy!
Notes
Please Note: I highly recommend using a kitchen scale to weigh your dry ingredients. Metric measurements are found above under the "Metric" tab.Measuring Flour: Either measure your flour using a kitchen scale or use the proper scoop and level method.Storage and Freezing Instructions:The cake can be stored covered at room temperature for 3-4 days. You can store leftover buttercream in an airtight container in the freezer for up to 2 months. Thaw it in the fridge then re-whip it using a handheld or standing mixer before frosting the cakes.
