Ingredients

Ingredients for cupcakes and frosting

Sugar: Granulated sugar sweetens the cupcake batter as well as helping it to stay moist. Powdered sugar is used in the peanut butter frosting to create a smooth, fluffy consistency that’s not at all grainy.

Flour: A combination of cake flour and all-purpose flour ensure your cupcakes will be pillowy-soft yet sturdy enough to stand up to a generous application of buttercream. If you aren’t familiar with cake flour, check out this post–> What Is Cake Flour?

Cocoa: Natural unsweetened cocoa powder is chocolate in its purest form. No fat or sugar gets in the way of its deep, dark, chocolate flavor.

Leavening: A combination of baking powder and baking soda helps these cupcakes to rise sky-high.

Salt: Balances the flavors and helps to carry them. I like kosher salt best because it’s cheap, easy to source, and doesn’t contain any bitter-tasting additives like iodine.

Butter: Gives both the cupcakes and the frosting the richest flavor!

Eggs: Use large chicken eggs (preferably at room temp to avoid a lumpy batter) or a plant-based product that can swap 1:1.

Buttermilk: The natural acidity in buttermilk works together with the leavening to help the cupcakes rise, as well as keeping them moist and adding a lovely flavor. If you don’t typically keep buttermilk on hand, you can use the same amount of sour cream, or check out this post–> How to Make Homemade Buttermilk.

Vanilla: The sweet perfume that vanilla extract gives complements the taste of chocolate beautifully.

Milk: You’ll need a little splash of milk or cream to thin the peanut butter frosting to the perfect consistency. Use whatever kind you keep on hand; even a plant-based product will work!

Expert tips

Use no-stir peanut butter: For best results, use a no-stir peanut butter. Peanut butter that requires stirring might have a thinner or thicker consistency, which can alter the texture of the frosting.

Don’t overmix the batter: Overmixing ingredients can lead to cupcakes that are more dense.

Weigh your ingredients: You’ll see gram measurements included with the dry ingredients. If you have a kitchen scale, weighing the ingredients instead of using measuring cups will help you get consistent results every time!

Frequently asked questions

Are these cupcakes gluten-free?


These cupcakes contain all-purpose flour and cake flour, so they are not gluten-free.

You could however try swapping in a gluten-free flour blend. This is just the kind of recipe where that could work well.

Can these be stored at room temperature?

Because the frosting contains milk, leftover cupcakes should be stored in the refrigerator.

How many cupcakes is one serving?

Each serving is calculated for one cupcake. The nutritional info given does not include the chocolate syrup drizzle.

Instructions
 

Prepare the chocolate cupcakes

  • Preheat the oven to 350 degrees F. Line a cupcake pan with liners. Optionally, you can spray them lightly with baking spray to make it easier to peel the cupcakes.
  • Place the sugar, all-purpose flour, cake flour, cocoa, baking powder, baking soda, and salt in a large mixing bowl. Whisk to combine.
  • Add the butter and mix on low speed for a few minutes, until the mixture resembles moist crumbs.
  • Add the eggs, one at a time, scraping the bottom and sides of the bowl with a silicone spatula after each addition. Add the buttermilk and vanilla, scraping the bottom and sides of the bowl to be sure the ingredients are evenly combined. Beat on medium speed for 60-90 seconds to aerate the batter and build the cake’s structure.
  • Fill lined cupcake wells just over half full (approximately 1/4 cup of batter).
  • Bake for 15-20 minutes, or until a cake tester inserted in the center of a cupcake comes out clean or with moist crumbs.
  • Cool completely before frosting.

Prepare the peanut butter frosting

  • While the cupcakes are cooling, prepare the frosting. In a large bowl, beat together the butter, peanut butter, vanilla and salt until smooth.
  • Slowly add in the powdered sugar, about 1/2 cup at a time, on low speed until evenly combined, scraping down the sides of the bowl a few times.
  • Add the milk on low speed, mixing until evenly combined. Increase speed to high and mix for an additional 20-30 seconds.
  • Pipe the frosting onto cupcakes. Top with chocolate sauce, if desired.
