1/2 cup butter
1 package Bob's Red Mill Chocolate Cake Mix
3 tablespoons unsweetened cocoa powder
1 1/3 cups milk
1 tablespoon plus 1 teaspoon lemon juice (or vinegar)
3 large eggs
2 teaspoons vanilla
Preheat oven to 350* F.
Combine milk and lemon juice. This mixture will curdle and become buttermilk. [If you have buttermilk use 1 1/3 cups of that and omit the milk and lemon juice mixture.]
Cream butter until soft and scrape sides of the bowl. Add cake mix & cocoa powder and mix briefly. Add milk/lemon juice mixture, eggs and vanilla and mix until everthing is incorporated.
Spoon into cupcake forms or 2 8"cake pans brushed with chocolate pan release.* Bake according to package directions. [Using traditional cupcakes liners bake about 19-20 minutes. Using fancy/thick cupcake liners (aka Wilton nut cups) bake about 22-25 minutes.] Remove from oven and let cool about 5 minutes before turning out of pan.
