Cupcakes:
Combine dry ingredients (salt, baking powder, baking soda, flour) in a mixing bowl.
Cream together brown sugar, butter, vanilla extract, and vegetable oil. Add egg and mix.
Alternate adding dry ingredients and buttermilk to the creamed mixture, then fold in chocolate chips.
Scoop batter into cupcake liners and bake at 325°F for 17-20 minutes. Cool on a wire rack.
Frosting:
Heat heavy cream and brown sugar until sugar dissolves, then chill.
Heat-treat flour in the microwave until it reaches 165°F.
Beat butter until fluffy, then gradually add in cooled cream mixture, heat-treated flour, and powdered sugar. Adjust consistency with heavy cream.
Cookie Dough Balls:
Heat-treat flour in the microwave.
Cream sugar and butter, then add heavy cream and vanilla extract.
Mix in heat-treated flour and chocolate chips, then roll into small balls.
- Ensure eggs are at room temperature before baking by placing them in warm water for 10 minutes to prevent clumpy butter in the batter.
- Fill cupcake liners about ¾ full to avoid cupcakes sinking in the middle during baking.
- Test baking powder freshness by dropping a teaspoon into hot water; if it bubbles, it's good. Don't confuse baking powder with baking soda.
- Use oven thermometers for accurate temperature control to ensure even baking.
- For precise flour measurement, spoon flour into a measuring cup and level with a knife, or use a kitchen scale for better accuracy.
- Without buttercream, cupcakes can be made a day ahead and kept at room temperature. For buttercream, make it 3 days in advance and refrigerate, allowing it to soften before frosting.
- Edible dough balls can be made 5 days ahead and refrigerated, then brought to room temperature before use.
