Chocolate is the best thing ever! It can be added to any dessert to make it even more delicious, so how about some delicious chocolate cupcakes topped with chocolate buttercream?
Preheat oven to 350 F. Spray muffin tin with oil and line with cupcake liners.
Whisk flour, cocoa, baking powder, and salt in a large bowl.
Combine chocolate chunks and butter in a medium bowl. Set bowl over a saucepan with simmering water and stir until chocolate and butter are melted and smooth (it took about 10 min. for me). Alternatively you can use a microwave and melt in increments of 30 seconds. Remove bowl from heat
Mix sugar, vanilla, and yogurt.
Fold wet ingredients into dry ingredients and mix well until mixture is smooth.
Pour mixture into muffin tin, using a spoon.
Add 1 chocolate chunk to the middle of each cupcake
Bake until a toothpick inserted into the center of cupcakes comes out with a few moist crumbs attached, 15 to 20 minutes.
Let cool completely then decorate with chocolate buttercream.
