For everyone already off the boat for their New Year’s resolutions, I present to you…peanut butter toffee cupcakes (hooray!!). These delicious cupcakes combine two of my absolute favorite flavors: peanut butter and toffee. My family is obsessed with toffee so I knew I wanted to incorporate it into a peanut butter cupcake topped with peanut butter frosting. Why? Because why not, that’s why ;) This cupcake isn’t overly sweet which pairs well with the swirl of sweet frosting and toffee garnish.
You know the gooey chewy center of peanut butter cookies? That’s what this cupcake tastes like. It’s denser rather than a super fluffy cake, and I love that it is packed with that “peanut butter cookie” flavor! It’s a cake version of a peanut butter cookie. I like a little cake with my frosting (hey, I wrote a book called Frosting, what can I say?) so this delicious peanut butter buttercream pairs so well with this cake. I love to use a fluted tip and give it a big ol’ swirl on top!
Of course nothing is ever finished without some garnish. Hot fudge topping (straight from the store, y’all) is my favorite chocolate topping because it’s rich in flavor and thick enough that it doesn’t drizzle all the way over the cupcake liners and become a big mess. Top with a toffee bar piece for some toffee crunch, and ba-boom! Delish!
Q: Can I add extra toffee pieces to the frosting?
A: Absolutely! Add them into the cupcake batter too! Add as much toffee flavor as you love! No rules, ya’ll.
National Peanut Butter Day happens to be January 24th (don’t ask me how I know these things) so I happen to think these peanut butter toffee cupcakes would be the perfect way to celebrate, don’t ya think?
