The December Daring Bakers’ Challenge had us all cheering – the lovely and talented Bourbonnatrix of Bourbonnatrix Bakes was our hostess and challenged us to make fun, delicious and creative whoopie pies! Delicious little cake-like cookies sandwiching luscious filling in any flavors we chose… What else is there to say but “Whoopie!”
This month’s challenge was perfect for answering the question of what to make for holiday desserts. For some reason I never got onto the whoopie pie bandwangon so I was glad to give these a try and see what my family thought. Since we were encouraged to play around with the flavor combination of cake and filling, I took my inspiration from a Secret Santa gift I received right as the challenge for the month was announced.
My Santa was from Canada, and she sent me (among other things) a can of Tim Horton’s English Toffee Cappuccino mix. As I was reading the sample recipe for chocolate whoopie pies I saw espresso powder as an ingredient and thought, hey, why not use the cappuccino mix instead? I also used the mix for half of the cocoa called for (only half as I didn’t want to overpower the pies for the non-coffee fans at dinner) and the end result was a nice mocha toffee coffee flavor that even Todd enjoyed.
For the filling I went with the usual marshmallow-cream filling, but I didn’t really want to use the standard vegetable shortening it called for, so I subbed coconut oil figuring it had the same texture with a much more pleasant flavor, too. On top of that, I added a generous pour of maple syrup to make it maple-marshmallow filling, in honor of the Canadian theme of the whoopie pies. Even if I never make whoopie pies again, the maple-marshmallow filling may be making future appearances in our home–it was just that tasty.
They made for very rich desserts, so some opted to split a pie among them so they could also sample some of the other desserts, too. Knowing that, I almost wish I’d made the mini-pies. Either mini or full-sized, I can see my little brother requesting these again!
Gluten-Free Toffee Coffee Whoopie Pies with Maple Marshmallow Creme Filling
Adapted from : King Arthur Flour
Servings: 8 large or 16 small whoopie pies
For the Whoopie Pies
1/2 cup (1 stick) unsalted butter
1 cup brown sugar, firmly packed
1 teaspoon Tim Horton’s English Toffee Cappuccino Mix
1 teaspoon baking powder
1/2 teaspoon baking soda
3/4 teaspoon salt
1 teaspoon vanilla extract
1 large egg
1/4 cup Dutch-process cocoa, sifted
1/4 cup Tim Horton’s English Toffee Cappuccino Mix
2 1/3 cups Gluten-Free Flour Blend
3/4 tsp xanthum gum
1 cup milk
1) Preheat oven to moderate 350Â°F/180Â°C/gas mark 4. Lightly grease (or line with parchment) two baking sheets.
2) In a large mixing bowl, beat together the butter, brown sugar, cappuccino mix, baking powder, baking soda, salt, and vanilla till smooth. Add the egg, again beating till smooth.
3) Add the cocoa and remaining cappuccino mix, stirring to combine.
4) Add the flour to the batter alternately with the milk, beating till smooth. Scrape down the sides and bottom of the bowl, and beat again briefly to soften and combine any chunky scrapings.
5) Drop the dough by the 1/4-cupful onto the prepared baking sheets, leaving plenty of room between the cakes; they’ll spread. A muffin scoop works well here.
6) Bake the cakes in a preheated moderate oven for 15 to 16 minutes, till they’re set and firm to the touch. Remove them from the oven, and cool on the pans. While still lukewarm, use a spatula to separate them from the pan or parchment; then allow to cool completely.
For the Maple Marshmallow Creme Filling
1 cup coconut oil
1 cup confectioners’ sugar or glazing sugar
1-1/3 cups Marshmallow Fluff or marshmallow creme
2 Tbsp maple syrup (or more, to taste)
1) (To make the filling:) Beat together the shortening, confectioners’ sugar, and marshmallow until well combined.
2) Add the maple syrup, and beat until smooth. If the filling is too thin, add confectionersâ€™ sugar until desired consistency is reached.
Pipe or spread a generous helping of filling onto the flat side of one pie and top with another.
