Prepare your muffin tin with 12 large muffin cases and pre-heat oven to 175 C / 347 F (no fan).
Melt butter and chocolate in a bowl over simmering water over medium heat
In another bowl, whip together the eggs with sugar with the help of an Electric hand mixer until pale, for about 5-7 minutes
Pour the melted butter and chocolate mixture into the egg-sugar mixture, and combine with a Rubber spatula. Do not use a mixer at this point
Sift in flour, salt, and cocoa powder and fold the mixture together. Do not overmix
Pour or pipe the batter into the prepared muffin cases and bake for 25 minutes
The brownie cups are ready when the edge looks baked and the middle looks slightly gooey but not raw. Do not over-bake! They will further set as they cool
Red white blue frosting
Whip cream cheese, mascarpone and powdered sugar with an electric hand mixer for 2-3 minutes. When the frosting reaches a fluffy, pipeable consistency, stop right there and do not overmix. If you continue beating the frosting, it will separate and gets runny.
Divide the frosting into 3 equal quantities. Leave one of them as it is and color 2 of them with blue and red.
Place the 3 different colors next to each other onto a kitchen foil. Roll up the kitchen foil and place it into a piping bag fitted with a star nozzle tip. Pipe frosting on top of the brownie muffins.
Serve the muffins fresh or store them refrigerated for 2-3 days in an air-tight container.
Notes
INGREDIENT NOTES
Use always unsalted butter in dessert recipes, but make sure you add the salt stated in the recipe as that will balance the sweetness
Use a combination of white and (light or dark) brown sugar for the best texture and beautiful butterscotch flavor
The egg should be used at room temp
The quality of the chocolate chips, along with the quality of the cocoa powder, will define the taste of your brownies, so try to use high-quality ingredients
Use high
-fat cream cheese and mascarpone for the frosting
High-quality gel food coloring is key to coloring the frosting. Lower-quality eg. liquid food coloring won´t provide bring results and might even break the frosting.
TECHNIQUE NOTES
A digital scale is required for a consistent, happy baking experience:)
Melt chocolate over a double boiler or in the microwave so you won´t burn it
Always pre-heat your oven and consider using a digital oven thermometer for the best results
Each oven is different, so you might need to adjust the baking time slightly
Do not overwhip the frosting, as it can become runny.
