Sweet & Salty Pretzel Nutella Cake Recipe

Preheat the oven to 350˚F and prepare three 6-inch cake pans or two 9-inch cake pans by spraying the sides with cooking spray and fitting a parchment or wax paper circle to the bottom of each pan. 

In a food processor, grind the salted pretzels into fine crumbs. Keep in mind that 1 1/2 Cups of whole pretzels equals about 2/3 cups of finely ground crumbs. Place the ground pretzels into a medium sized bowl and add the sifted cake flour, baking powder, baking soda, and salt. Whisk to combine and set aside. 

In the bowl of your stand mixer (a handheld mixer works fine too!), cream the butter for on high for two minutes until it's light and fluffy. Add in sugar and continue to mix on high for another two minutes, scraping down the bowl and paddle as needed. Add the eggs one at a time, mixing thoroughly after each addition. Add vanilla and sour cream and mix for one minute on high, scraping down the bowl and paddle once more. 

With the mixer on low speed, add in the dry ingredients and mix until just combined. Add the milk slowly and mix until just incorporated. Scrape down the sides and bottom of the bowl and give it a few stirs to make sure there are no lumps (without over-mixing). The batter will be slightly thick, but pourable. 

Pour batter evenly into prepared cake pans (no more than 2/3 of the way full) and bake for 30-35 minutes. They're done when they spring back to the touch and a toothpick inserted into the middle comes out clean. Let the cakes cool in the pan for five minutes before turning them out onto a wire rack for an additional few hours of cooling. Make sure they're entirely room temperature before applying any frosting. 

With a hand mixer or paddle attachment on your stand mixer, cream the butter on medium-high until it’s creamy and light in color, about 5 minutes.

Add the sifted powdered sugar a few cups at a time, scraping down after each addition and making sure each cup is fully incorporated before adding the next one. Add the Nutella and beat on med-high for a full minute. Add vanilla, milk, and salt and mix on medium-low for another minute until fully incorporated. 

Measure Nutella into a heatproof bowl and set aside. In a saucepan over medium-high, heat the heavy whipping cream until small bubbles form (just before the start of a rolling boil), stirring constantly with a whisk. Once the cream begins to boil, remove the pan from the heat and pour the cream over the Nutella. Let sit for about 30 seconds before whisking together until the consistency is uniform and well blended. Let it cool to room temperature before using on the cake. 

Once the Pretzel Cakes have cooled completely, use a cake leveler to torte them before filling and frosting with the Nutella Buttercream. To create the design pictured, create a smooth Nutella Buttercream finish and add salted pretzel bits around the bottom third of the cake.

Place the cake in the refrigerator for about 30 minutes before dripping with Nutella ganache (here are some drip cake tips for success if you need them!), then place the cake back into the refrigerator for another 5-10 minutes to let the Nutella ganache set up. Finish by piping swirls of Nutella Buttercream around the top edge of the cake with Wilton Tip 1M and add more salted pretzels wherever you'd like!
