You can substitute coconut flour for almond flour (simply use half the quantity) if you want to make the recipe nut-free. Additionally, if you don’t have a microwave or would prefer not to use one, you can adjust to make it an oven recipe. Simply preheat the oven to 350, making 4-8 servings of the cake in individual oven-safe ramekins (place the ramekins on a baking tray to catch potential spillage). Cook 12-15 minutes until lightly browned and set. Follow the traditional instructions for the coffee liquid and topping.
