S’mores Cake & Cupcakes

This has been our summer of s’mores. It began in early June with a campfire and a family week in the mountains. On that trip, we even found ourselves manning a s’mores table at a race expo in West Yellowstone. We were up to our elbows in sticky melted marshmallows, Hershey’s chocolate and graham cracker crumbs. Still, we could have eaten more of them.

Before summer gets away from us, we’re spending some weekend time baking up this s’mores-inspired cake. The result is a tender graham cracker cake, a thick layer of rich chocolate ganache, and toasty “marshmallow fluff” frosting. Summer on a cake stand.

We’ve taken some liberties with this one. The chocolate is dark and the fluffy white frosting isn’t what it looks like. Instead of whipping up a traditional marshmallow cream, we’ve whipped up a bit of aquafaba (seriously cool stuff), sweetened it with sugar and lathered it on the cake. A kitchen blowtorch makes toasting a snap.

If you’re not familiar with aquafaba, welcome to one of 2016’s biggest food trends. Aquafaba is essentially the brainchild of some very clever French and American food geeks who figured out that the liquid in a can of garbanzo beans contained enough of certain bean proteins that it could be whipped like egg whites to create foam. As it turns out, aquafaba is more than just a passable substitute for egg whites. Aquafaba foam is more stable for longer periods of time and at a wider range of temperatures. It’s also much harder to over whip and break because it doesn’t dry out quickly. It can be flavored and colored to suit the use (think meringue, French macaroons), pavlovas, etc.). And, it’s also vegan. Although, that doesn’t seem to matter to us too much since we’re using butter, eggs, and cream in the cake and ganache recipes. However, we’re always game to try the latest food trends and incorporate them into our recipe repertoire.

S’mores Cake
one 6-inch cake with a 6-pack of cupcakes

Graham Cracker Cake

1 cup all-purpose flour
1 cup graham cracker crumbs, finely ground
3/4 tsp baking powder
1/4 tsp baking soda
3/4 tsp salt
2/3 cup butter, room temperature
2/3 cup light brown sugar
1/3 cup granulated sugar
3 large eggs
2/3 cup kefir
2 tsp vanilla

Dark Chocolate Ganache

Aquafaba Marshmallow Fluff

Preheat oven to 350F and grease and flour a 6″ cake round and line with parchment. Grease and flour, or use cupcake papers, for 6-7 muffin spaces. Set aside.

In a medium bowl, whisk flour, graham cracker crumbs, baking powder, baking soda, and salt until well combined. Sift through a fine sieve and slowly push through most of the graham and flour until only small graham cracker crumbs are left. Add the crumbs to the flour mixture and set aside.

Using a stand mixer fitted with the paddle attachment, beat butter until smooth.
Add sugars and beat on med-high until pale and fluffy (2-3mins).
Reduce speed and add eggs one at a time, fully incorporating after each addition. Add vanilla.

Alternate adding flour mixture and kefir, beginning and ending with flour (3 additions of flour and 2 of kefir). Fully incorporating after each addition. Do not over-mix.

Spread batter evenly into prepared pans. Smooth the top with a spatula and gently whack the pans against the counter to evenly distribute and release any air bubbles.
Bake the cupcakes for 12 minutes then rotate the pan and bake another 12 minutes or until the cupcakes bounce back from a light touch. For the 6-inch cake. Bake for approx. 40 mins or until a toothpick inserted into the center comes out mostly clean.

Place cakes on wire rack to cool for 10 mins. Run a knife around the edge of the pan and cake to loosen. Gently remove the cakes from the pans, set on racks and allow to fully cool before continuing.

 

Dark Chocolate Ganache

5.25 ounces dark chocolate (1 1/2 bars TJ’s 3.5 ounce dark chocolate bars)
4 ounces heavy cream
2 tablespoon soften butter
pinch of salt

Chop the dark chocolate and place it in a heat proof bowl. In a small sauce pan over medium-low heat bring the heavy cream to just about a boil. Remove from heat and pour over the chocolate, add a pinch of salt, and let sit for a minute or two, then whisk the chocolate and cream together. Once all the chocolate is incorporated, add the butter.

Allow the ganache to cool at room temperature for a couple of hours or in the fridge for about 30 minutes before continuing.

Aquafaba Marshmallow Fluff
(adapted from Chocolate Covered Katie)

1 15-ounce can garbanzo beans
1/4 teaspoon cream of tartar
1/2 cup ultra fine (baker’s) sugar
1 teaspoon vanilla

Drain the garbanzo beans into a bowl with a lid. Use the garbanzo beans for another use. Refrigerate the bean water over night. We think chilling it makes for a shorter whipping time.

In a stand mixer with the whisk attachment or using a handheld mixer, add the refrigerated bean water and cream of tartar to the mixing bowl and mix on medium-high speed. Once double in volume, add the ultra fine sugar and vanilla. Whisk until peaks reach desired stiffness. The bean water seems to hold up well to over-mixing.

Assembling the cakes:

Split the 6 inch layer cake in half and add 2/3 of the chocolate ganache to the split layer. Spread until to the border of the cake and top with the other split layered cake. Spread a thin crumb coat over the sides of the cake. Wrap in plastic and refrigerate at least 30 minutes, or up to a day or two. Freeze the cake at that point for up to a month before frosting.

Top the cake with a very big dollop of the fluff. Using an off set spatula, smooth over the top and sides using swishing with flourishes to the cake. This is an excellent beginner decorator frosting.

Cupcakes:

With the rest of the ganache, divide between 6 or 7 balls (depending on how many cupcakes are left). Gently and quickly roll the balls between hands. Freeze until ready to use.

With a melon baller, scope a small amount of cake out of the top center of the cupcake. Place the frozen ganache in the hole. Frost the cupcake in a variety of ways, with a pastry bag, using a big ice cream scoop, or just a spooned dollop on top. Toast the marshmallow using a home creme brûlée kit or a more toolbox-type blowtorch. A quick sit under the broiler may work also to get some color on the fluff, but it could also melt the chocolate. Who knows?

Pantry Staples: Roasted Beets and Pickled Beet Greens

Beets are a year-round veggie staple here in California. The varieties available to us vary throughout the year, but beets in some form are available at just about every farmers market around, not to mention the big grocery chains. And like potatoes, they’re crazy adaptable, perfect in spring salads, earthy breakfast hashes, and chocolate cake. They’re better roasted than boiled. We scrub them clean, trim their greens and wrap them in foil to roast in a hot oven. Roasted beets are easy to peel once they cool a bit. They’ll keep in the fridge for a week in a sealed container.

Garden variety red beets are sweet and delicious. But if you’re able to get your hands on some beautiful golden or variegated varieties like chioggia beets, buy them. Their colors are beautiful and less likely to “bleed” than dark red varieties like Bulls Blood. We’ve roasted beets that look like jewels after roasting, with beautiful golds and pinks swirling around in them. They’re a fun way to play with color and texture in all kinds of dishes.

When we’re on our game, we buy beets with greens, rather than trimmed bulk beets, because the greens are delicious and they’re nutritious, long stalks and all. They’re tender enough to eat raw, but their mild flavor makes them endlessly useful in any recipe that calls for fresh greens. We use them in soups and risottos for added color and bite. We really love these pickled beet greens. They’re crunchy, vinegary and a little spicy, the perfect partner to anything you’d embellish with hot sauce or salsa or pickles. Of course, you can pickle just about any green, but if you’re looking to put a bunch of beet greens to better use than building compost, pickle them.

Roasted Beet Roots

A bunch of beets (4-5 beet roots) with the greens intact
2 tablespoons olive oil
Salt
Preheat the oven to 425 degrees.

Cut the stems from roots, setting the stems and leaves aside in cold water to clean and hydrate. Scrub the beet roots with a bristly brush to remove all mud and dirt. Dry the beets with paper towels.

On a baking sheet or in a roasting pan, place a large piece of aluminum foil in the bottom, enough to fold over the beets. Place the beets in the center of the foil and drizzle about 1-2 tablespoons of olive oil over them. Sprinkle liberally with salt, 1-2 tablespoons. Seal the beets inside the foil. Put the tray in the oven and roast for 40-60 minutes or until a knife pierces a beet easily. Remove from the oven and let cool for about an hour. Once cool enough to handle, using paper towels, peel the skins off the beets. The skins should easily slip off. Sometimes a paring knife is useful for peeling the beets if you want to take a more fussy approach.

Once the skins are removed, the beets can be sliced, diced, or served quartered. Keep them refrigerated and use in a salad or add to potato hash.

Pickled Beet Greens

Stems and leaves from a bunch of beets, and/or other greens
1/2 cup distilled vinegar
1/2 cup apple cider vinegar
2 tablespoons sugar
a good pinch of chili flakes
a good pinch of salt
pepper

In a medium pan, fill halfway with water. Bring to a boil and reduce to a simmer. Meanwhile, clean and hydrate the beet stems and leaves in a bowl of ice water. Spin dry and separate the stems and leaves. Chop the stems into 1/8” pieces. Set aside. Combine all the leaves as tightly as possible, layering leaves on top of one another. Roll tightly, chop into 1/8”-1/4” strips. Chop the strips a few times to get smaller pieces. Set aside.

Add a pinch of salt to the boiling water then add the beet stems. Simmer for 3 minutes, then add the beet leaves. Simmer for 3 more minutes. Drain the stems and leaves (the water can be saved and used to flavor soups). Move the hot greens to a mason jar.

Over medium heat in a small pan, heat the vinegar, sugar, chili flakes, and salt. Heat until it almost comes to a boil. Pour the hot vinegar over the stems and leaves. Cover and allow to sit at room temperature until the stems cool completely. Once cooled, refrigerate for at least three days before using.

Add pickled beet greens to salads, soups, toasted bread, pizza, rice bowls.
