My second cupcake for this month’s IronCupcake challenge is based on the song “Heart of Glass” by Blondie. It’s one of those songs that always manages to make its way in to my brain and get stuck there for hours.
The cupcake is a blondie cupcake with mascarpone frosting, topped with a sugar “Heart of Glass”.
I’ve mentioned before that I am addicted to music. Well, I think I might have understated it just a bit. I have over 1200 songs in my library at the moment. That number is constantly growing as I discover new artists or songs. The genres range all the way from rock to classical and everything in between.
Some people have gone as far as to call me obsessed. That’s such a harsh word; I prefer the term extremely fascinated. Plus, there are people that have way more songs than I do. So, in other words, I’m not alone. Check out just a few of my current favorite songs.
Anyway, while I’m not a massive fan of Blondie (the group), I am however a massive fan of blondies (the dessert). Put them in cupcake form and I’m not sure life could get any better. The combo of butterscotch and toffee bits make these cupcakes amazing. I was imagining them to come out a with the texture of a cupcake but no, these are like actual blondie bars. Perfection!
Okay, back to the point of this whole post… the cupcakes!!

Blondie Cupcakes – Makes about 12 cupcakes
adapted from Martha Stewart’s Cupcakes
1 2/3 cups all-purpose flour
3/4 teaspoon salt
1 teaspoon baking powder
1/2 cup (1 stick) plus 1 tablespoon unsalted butter, room temp
1 cup packed light-brown sugar
2 large eggs, room temp
1 teaspoon pure vanilla extract
1/3 cup toffee bits (or chopped Heath or Skor chocolate covered toffee bars)
1/3 cup butterscotch chips
Preheat your oven to 350°F and line a muffin tin with paper liners. Whisk the flour, salt and baking powder together.

Cream butter and brown sugar on medium-high speed until pale and fluffy. Add the eggs and vanilla and beat until combined. Reduce the speed to low and add flour mixture; beat until just incorporated. Fold in the toffee bits and butterscotch chips by hand.

Divide the batter into the lined cup, filling each three-quarters full. Bake at 350°F for 23-25 minutes until golden brown. Allow the cupcakes to cool completely before removing them from the pan.

To make the sugar hard candy, I combined 1 1/2 cups sugar, 1/2 cup water and 3/8 teaspoon cream of tartar in a saucepan over medium heat.
Stir until sugar is dissolved, about 4 minutes. Without stirring, let the mixture come to a boil (about 5 minutes). Raise the heat to high and let it continue to boil until the temperature on your candy thermometer reaches 300°F. Remove from the heat and let the mixture cool just until it stops boiling (it will still be very hot). Add 4-5 drops of red food coloring and mix quickly. Pour the mixture onto a greased cookie sheet.
Allow it to cool a minute and press the greased cookie cutter into the mixture (it should be set enough to hold the shape). Once it’s almost cool, break apart the hearts. Don’t worry if you break a few. I started with 16 and ended with 12.
I used a Wilton cookie cutter
for the shape.

Mascarpone Frosting – Makes about 2 cups
adapted from Martha Stewart’s Cupcakes
1 cup heavy cream
8 ounces mascarpone cheese, room temp
1/2 cup confectioners’ sugar, sifted
With an electric mixer, whisk heavy cream on medium speed until stiff peaks form. In a medium mixing bowl, whisk together mascarpone and confectioners’ sugar until smooth. Gently fold the whipped cream into the mascarpone mixture until completely incorporated. Use immediately.
