Instructions

For The Cake:

  • Heat oven to 350 degrees Fahrenheit.
  • Generously grease an 8 inch round cake pan (can use a 9 inch round cake pan if that's what you have) with butter. Coat the pan with some gluten free flour blend to prevent sticking.
  • Place ½ cup of unsalted hazelnuts in a food processor and pulse until they are finely ground. Alternately, you can place the hazelnuts in a plastic Ziploc bag and pound with a rolling pin if you don't have a food processor.
  • In a mixing bowl, combine 1 scant cup gluten free flour blend (this equals 120 grams and can be measured with a kitchen scale), ½ cup finely chopped hazelnuts, 2 tsp. baking powder, and ¼ tsp. kosher salt. Mix all of these ingredients together.
  • In a separate bowl, cream 4 Tbsp. of room temperature unsalted butter and 1 cup of sugar using a hand mixer or the whisk attachment of a Kitchen Aid stand mixer until the mixture is light and fluffy.
  • Add 2 eggs to the butter and sugar mixture one at a time, mixing until the mixture is light and fluffy after each egg is added.
  • Fold the flour mixture into the egg mixture a little at a time. Add some of the flour, mix together, and repeat until it is completely combined. The batter is thick and dense.
  • Spread the batter evenly in pan and bake for 35 minutes or until toothpick comes out clear. Remove from oven and allow to cool completely.

For The Chocolate Frosting:

  • Brew one cup of coffee or espresso and allow to cool.
  • Heat a small amount of water in a double boiler (the water should be hot, but not boiling). Place 2 oz. of semisweet baking chocolate in the boiler and allow to melt, stirring the chocolate with a spatula to prevent burning.
  • Add 1 ½ Tbsp. unsalted butter to the chocolate and stir until the butter has melted and incorporated into the chocolate. Pour the chocolate mixture into a bowl and allow to cool.
  • Once the chocolate has cooled, beat the mixture with a hand mixer or the whisk attachment of a Kitchen Aid stand mixer until smooth. This may take a few minutes.
  • Add 2 Tbsp. of cooled coffee and 1 Tbsp. Frangelico liqueur to the mixture. Continue to beat with a mixer until it is spreadable.
  • Remove cake from pan and place on a cake platter or large plate (you may need to run knife along sides of pan to remove). Spread the chocolate frosting evenly over the top of the cooled cake.
  • Add ½ cup roughly chopped unsalted hazelnuts on top of the cake.

Notes

I recommend using a gluten free flour blend such as Bob's Red Mill 1 to 1 Flour or Cup 4 Cup even if gluten is not an issue for you for the best results.
Gluten free flour blends absorb liquids more than AP flour. As a result, it's best to reduce the amount of gluten free flour to 120 grams instead of using a full cup, as the original recipe calls for.
A kitchen scale ensures that the measurement of the flour is accurate and the cake won't dry out.
