tips and tricks for a perfect small cake

best substitutions for this recipe:

    • this is preferred for this recipe, but if needed use
    • unsweetened cocoa powder
    • omit the baking powder and use 1/4 tsp baking soda

    • for a buttery taste, use melted butter
  • sour cream
    • use a full fat thick yogurt such as skyr or greek
    • this wasn’t tested with a dairy free yogurt, but I think one could work well
  • whole milk
    • sub with any milk of choice
    • however the higher fat content, the better
  • tahini
    • any natural nut butter works well here
    • use one that pairs well with chocolate, such as peanut butter

  • 1/3 c (76g) tahini, well stirred

Instructions
 

small chocolate cake

  • Preheat the oven to 350F (177C). Lightly spray and line the bottom of a 6" cake pan with parchment paper.
  • Prepare the espresso according to the package directions. Add the chocolate chips into the hot espresso. Set aside.
    Sift the flour, cocoa powder, baking powder and salt into a medium sized bowl. Whisk until well combined with no lumps. Set aside.
  • In a large mixing bowl, whisk the oil, sugar and egg until smooth and well combined. The mixture should be very smooth and pale yellow in color.
    Whisk in the sour cream until smooth and well combined. The mxiture will slightly resemble egg whites that have been whipped for a few minutes. In other words, the mixture should remain very smooth and will look very pale yellow.
  • In this order, add the dry ingredients and milk to the wet: dry, milk, dry. Whisk each addition until just combined. A few flour or milk streaks is OK.
    While whisking, pour in the melted chocolate/espresso mix. Whisk everything until smooth, almost glossy and well combined.
  • Pour the batter into a prepared 6X2 or 6X3 (preferred) cake pan. The batter will be runny, so this should be easy.
    Bake at 350F (177C) on the center rack of the oven for 35-40 minutes. After 30 minutes of baking, take a look at the cake. If the center still looks wet, let the cake bake an additional 5 minutes.
    At 35 minutes look for the signs the cake is done baking: the edges of the cake will pull slightly away from the pan. A toothpick inserted into the center will yield a few moist crumbs. When a finger is pressed into the top of the center of the cake, the cake should bounce back. If the batter leaves an imprint of the finger, give the cake another 3-5 minutes to bake before checking again.
  • Cool the cake in the pan placed on a cooling rack for 10-15 minutes. Invert the slightly cooled cake onto the rack. The cake should easily slide out of the pan. If not, use a butter knife to gently release the edges of the cake from the pan.
    Cool the cake completely before adding the buttercream. After an hour cooling at room temperature, the cake can be moved to the fridge to chill before applying the buttercream.

tahini buttercream

  • In a stand mixer, with paddle attachment, beat butter until light and fluffy, about 4-5 minutes. On the lowest speed, beat in the tahini with butter until well combined. Add 1/2 c powdered sugar, vanilla extract ans salt. Beat on low-medium speed until well combined. Add the remaining half of the sugar, a generous tablespoon at a time, beating until well combined. Once all the sugar is added, beat frosting on med-high until smooth.
  • Apply a light crumb coat the the completely cooled chocolate cake. Chill the cake in the fridge for 15-20 minutes. Apply a thicker final layer of buttercream to the cake as desired. Top with chocolate shavings and/or chocolate sprinkles.

Notes

the total weight of this batter is 500g or about 2 1/4 c liquid. This amount fills a 6X3 round cake pan half way. If using a 6X2 cake pan, the cake may require a few more minutes of baking. 
  • if using this recipe to make cupcakes, it should yield about 6 cupcakes. bake for about 18-25 minutes. 
dutch process cocoa powder was used to develop this cake. after many rounds of testing, I can say that if needed, this can be subbed with unsweetened cocoa powder. if this is done, omit the baking powder and use 1/4 tsp baking soda instead.
canola oil was used for its moisture and neutral taste. melted butter, olive oil or vegetable oil can be used as a substitute. 
hot espresso enhances the intensity of the chocolate. if needed, hot water or even chai tea can be used as a substitute.
whole milk and whole fat sour cream or yogurt works best in this recipe. I would not use a fat free or low fat substitute for these ingredients.
