Ingredients

  • 1.5 cups certified gluten-free almond flour
  • 0.75 cup granulated sugar
  • 0.5 cup unsalted butter, softened
  • 2 large eggs
  • 1 tsp pure vanilla extract
  • 0.5 tsp salt
  • 1 cup gluten-free chocolate chips, melted
  • 2 tbsp strong brewed coffee or espresso, cooled

Instructions

  1. 1

    Preheat your oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper, ensuring it overhangs slightly for easy removal. This preparation will prevent sticking and ensure a clean release of the cake layers.

  2. 2

    In a large bowl, cream together the softened unsalted butter and granulated sugar using an electric mixer on medium speed until the mixture is pale yellow and fluffy, about 3-4 minutes. Gradually beat in the two large eggs, one at a time, ensuring each is fully incorporated before adding the next, then stir in the pure vanilla extract until just combined.

  3. 3

    In a separate medium bowl, whisk together the certified gluten-free almond flour and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined and no dry streaks remain; be careful not to overmix. Gently fold in the cooled strong brewed coffee or espresso until the batter is smooth and homogenous.

  4. 4

    Pour the batter into the prepared baking pan and spread it evenly with a spatula, ensuring the surface is smooth. The batter will be thick and should reach about ½ inch in thickness.

  5. 5

    Bake for approximately 20-25 minutes, or until a toothpick inserted into the center comes out clean and the edges are lightly golden brown. Allow the cake to cool in the pan on a wire rack for about 10 minutes before inverting it onto the rack to cool completely. Gluten-free baked goods often firm up considerably as they cool, so patience is key for the best texture.

  6. 6

    Once completely cooled, you can proceed with assembling your opera cake by layering with coffee-infused buttercream and topping with the melted gluten-free chocolate chips for a rich ganache. Slice and serve when chilled for the best flavor and texture.

Tips & Notes

  • Almond flour compacts easily — always spoon it into the measuring cup, never scoop directly.
  • Separate eggs when cold (the yolks are firmer), then let whites come to room temp before whipping.
  • Brown the butter before adding it for a nutty, caramel depth that elevates simple recipes.
