How to Make these Irresistible Cupcakes
This simple and delicious cupcake recipe has all of ten ingredients, including two types of chocolate that make a rich and luscious batter. You’ll start by melting the chocolate with butter in a large bowl over a pot of simmering water, like a double boiler. Once it’s completely melted and smooth, eggs, sugar and vanilla are mixed in followed by the dry ingredients. Then it’s just a matter of filling those muffin cups. So easy!
Key Tip: Be sure to fill the muffin cups a good three-quarters full to get that irresistible rounded dome. It will take all your might not to nibble on that warm brownie crust topping after baking.
The Nutella Filling
Let the brownie cupcakes cool a bit before cutting out wells for the Nutella filling. And try not to eat what you cut out! Sorry, but seriously. The tops of those little cones will serve as a plug for the Nutella. I found it easy to simply scoop the Nutella into a plastic sandwich bag and pipe into the wells.
How to Make the Frosting
When it comes to the frosting, it’s a simple buttercream recipe flavored with a bit of cocoa and a good splash of one of my favorite liqueurs, Baileys Irish Cream. I obviously wanted to give these Nutella Stuffed Brownie Cupcakes a St. Patrick’s Day spin but you can use whatever liqueur you prefer.
Once your cupcakes are filled, have fun piping away! Admittedly my piping skills can use improvement but it still tastes amazing. And, no cupcake got shortchanged. It’s all good. Have a fun St. Paddy’s Day! Enjoy!
