Notes
Ingredient Notes
Canola Oil: You can use vegetable oil, too.
Sour Cream: Avoid fat-free or reduced fat.
Instant Coffee: Use a good quality one for the best flavor. I used Starbucks Dark Roast.
Flour: Be sure to measure your flour correctly. Spoon it into your measuring cup and then level with a knife. Avoid dipping your cup into your flour container, as you'll likely overmeasure.
Tips
Use room temperature ingredients to help everything mix together smoothly.
Don't overmix your batter. This can make the cupcakes tough and gummy. Mix just until the flour disappears.
Make sure the water is hot enough to completely dissolve the coffee. We want that flavor, but not the texture of instant coffee.
Fill cupcake pan only ⅔ of the way full so your batter doesn't spill over and make a mess.
Please rice at the bottom of your cupcake pan to soak up excess grease so your wrappers don't get soggy.
