Sour Cream Coffee Cake with Chocolate-Cinnamon Swirls and Hazelnut Crumb Topping


There is just something about the holidays that cry out for decadent breakfast treats.  I love desserts - that's no surprise.  And I love making treats - the cookies, candies, etc.  But what I really, really love is taking the time to make something extra special and different for breakfast or brunch.

Add some insanely good hot chocolate to the menu, and as far as I'm concerned, you can call it good.  For a killer hot chocolate mix - which would make a stellar last minute Christmas gift - you can try my new recipe I came up with to follow up to last year's Hot Cocoa Mix.  This time around I shared a recipe for a homemade, from scratch, ridiculously decadent and addictive Salted Caramel Hot Chocolate Mix over on my friend Jyl's site, Mom It Forward.  I know there are many versions out there you can buy pre-made, but I wanted to come up with something that could be made completely at home. If I do say so myself, the recipe I came up with really knocks it out of the park.  Let's put it this way.  The recipe makes 2 1/2 lbs (but could easily be cut in half if you want) - I only made it about a month ago... and ended up only giving out about three small jars of it.... and it's all gone.  I'm pretty sure I'll be making more of the mix over the weekend - hopefully in time for Christmas morning.  Mommy is a whole lot nicer after she's had a good cup o' chocolate.  I'm just sayin'.


While I love a good coffee cake, when given a choice, any recipe that involves chocolate is going to come out ahead of the pack as far as I'm concerned. This particular cake - with it's tender sour cream crumb, nutty topping and chocolate-cinnamon swirls layered throughout - isn't terribly cumbersome to put together and makes plenty to share. It does take some baking and cooling time - you'll need just over an hour and a half, start to finish to mix, bake and cool this cake - so unless you are up early, it may be more of a brunch item - perfect after a round of gift exchanging and opening on Christmas morning.  I've included a few tips on how to cut your time down if you do want to serve it earlier in the morning - but that said, it keeps really nicely, so there isn't really any reason you couldn't just make it all the day before.

Sour Cream Coffee Cake with Chocolate-Cinnamon Swirls and Hazelnut Crumb Topping
Adapted from Baked: New Frontiers in Baking

For the Crumb Topping:
3/4 cup all-purpose flour
3/4 cup packed light or dark brown sugar
1/2 teaspoon salt
3/4 cup toasted, skinned hazelnuts
6 tablespoons cold butter, cut into small cubes

For the Chocolate-Cinnamon Swirls:
1/2 cup sugar
1 tablespoon good quality cocoa powder
1 teaspoon ground cinnamon

For the Sour Cream Cake:
3 1/2 cups all-purpose flour
1 teaspoon baking powder
1 1/2 teaspoons baking soda
1/2 teaspoon salt
1 cup (2 sticks) unsalted butter, a little bit softened, but still cool, cut into pieces
1 1/4 cups sugar
1 cup packed light brown sugar
4 large eggs
16 ounces sour cream
2 teaspoons pure vanilla extract

Make the Crumb Topping:
Pulse the flour, sugar and salt together in a food processor to combine.  Add the hazelnuts and process until finely chopped and mixed together.  Add the butter and pulse a few times to combine.  The mixture should look like coarse sand.  Place the mixture in a small bowl, cover with plastic wrap and keep the mixture in the refrigerator until ready to use.*

Make the Chocolate-Cinnamon Swirl:
Whisk the cocoa, sugar and cinnamon together in a small bowl.  Set aside.**

Make the Sour Cream Cake:
Preheat the oven to 350 degrees F. Butter a 9x13-inch baking pan, then line it with a piece of parchment with the edges hanging over the long sides to make a sling.  Butter the parchment and set the pan aside.

In a medium bowl, whisk together the flour, baking powder, baking soda and salt.***

In the bowl of an electric mixer with paddle attachment, beat the butter until well creamed and smooth.  Scrape down the sides of the bowl and add the sugars.  Beat the mixture until it is fluffy and light.  Add the eggs, one at a time, beating well after adding each egg.  Scrape the sides down again and then beat the mixture for 30 seconds more.

Add the sour cream and vanilla and beat the mixture until just mixed.  Add the flour mixture in three parts, scraping down the sides of the bowl in between each addition until just mixed - don't over mix!

Pour one-third of the cake batter into the bottom of the prepared cake pan and spread it evenly.  Sprinkle half of the chocolate mixture over the batter, covering the entire surface of the batter.  Spoon half of the remaining cake batter over the swirl mixture and spread it evenly.  Top the batter with the remaining swirl mixture, covering the surface again.  Spread the remaining cake batter evenly over the swirl, then sprinkle the crumb topping over the cake batter.

Bake the cake in the center of the oven, rotating the pan halfway through baking, for 1 hour or until a skewer comes out clean.  Let the cake cool in the pan on a wire rack for 30 minutes before serving.  Serve from the pan, or use the parchment as a sling to gently lift the cake out onto a cutting surface to cut into squares and serve.  The cake keeps well for up to 3 days, tightly covered, at room temperature.

* Make the Crumb Topping the day before you want to bake the cake and keep it in the refrigerator.
** Make the Chocolate-Cinnamon Swirl the day before you want to bake the cake to save a few minutes measuring and whisking.
*** To really cut down on your mixing time the morning of making this cake, measure and mix together the dry ingredients and set aside till ready to make the cake the next day.

If you follow all the pre-measure shortcuts, you'll just be left with creaming and mixing the actual cake batter and baking it the next day.

Oh, My!! I don't know which sounds more decadent - the Hot Chocolate or the coffee cake.

Also love to make decadent b'fast during the Christmas/New Years week.
