Lately, I‘ve been living by these words: Make It Count. In life, in work, and yes, even in food. Some fancy cupcakes look great, but by the time I put down my fork, it didn’t seem quite worth it.

How to make Chocolate Cupcakes from scratch:
First, brew some strong coffee, or grab an extra shot of espresso from your favorite coffee place. With an electric mixer, cream the butter and both sugars until light and fluffy.
Add the eggs, one at a time, and then the vanilla.
In a separate bowl, mix together the sour cream (gasp!) buttermilk, and that coffee you brewed.
In yet another bowl, mix together the dry ingredients: flour, cocoa powder, salt, and baking soda.
Take turns adding the wet ingredients and the dry ingredients to the butter and sugar mixture, while the mixer is on low speed. Don’t add everything at once, though, try to space it out into three batches. Mix until just blended.
Measure out 1/2 cup batter into each cupcake cup. I like to use cute cupcake liners, like these.
Bake at 350 degrees, for about 25 minutes, until a toothpick inserted in the center of a cupcake comes out clean. While the cupcakes are baking, it’s time to make the frosting.
How to make Peanut Butter Frosting:
To make the best peanut butter frosting you’ll ever have, mix together the peanut butter, powdered sugar, butter, vanilla, and salt with an electric mixer. You may have to scrape down the sides of the bowl, because this part can get sticky. Once that’s blended, slowly add the heavy cream. Beat on high speed until silky and smooth.
What can you use as a substitute for buttermilk?
Make your own buttermilk, or switch it out using one of these suggestions:
- For each cup of buttermilk, you can use 1 tablespoon of white vinegar or lemon juice plus enough milk to measure 1 cup. Stir, then let stand for 5 minutes.
- You can also use 1 cup of plain yogurt or 1 3/4 teaspoons cream of tartar plus 1 cup milk.
- Some people use a good quality plain, unsweetened yogurt in place of buttermilk, volume for volume.
Can you make this Chocolate Cupcakes recipe eggless?
If you’re avoiding eggs, you can use one of the following egg substitutes:
- Unsweetened applesauce: Using one-fourth cup of applesauce in place of one egg will work.
- Banana: Using one-fourth cup of ripe, mashed banana in place of one egg might be a nice substitution.
- Make a chia seed or flax seed egg: To replace one egg, whisk together 1 tablespoon of ground chia or flaxseeds with 3 tablespoons of water until fully absorbed and thickened.
What is the best cocoa to use for baking?
I love a deep velvety cocoa like the kind Guittard makes. It can be found online, and it also makes phenomenal hot chocolate.
