Yield
Serves 8 generous slices
Difficulty Level
Medium – ideal for home bakers pleasant with keto baking techniques
Ingredients
- 1 ¾ cups almond flour,finely ground
- ½ cup finely chopped walnuts,toasted
- 1 tbsp ground coffee or espresso powder
- 1 tsp baking powder,gluten-free
- ½ tsp xanthan gum (for extra structure)
- 4 large eggs,room temperature
- ½ cup erythritol or preferred keto granulated sweetener
- ¼ cup melted unsalted butter
- ⅓ cup brewed strong coffee,cooled
- 1 tsp vanilla extract
- ¼ tsp fine sea salt
Instructions
- Preheat your oven to 350°F (175°C). Grease and line a 9-inch round cake pan with parchment paper for easy release.
- Toast the walnuts in a dry skillet over medium heat, stirring frequently until fragrant and golden (about 5 minutes).Set aside to cool.
- Mix dry ingredients: In a large bowl, whisk together the almond flour, baking powder, ground coffee, xanthan gum, salt, and half of the toasted walnuts. this ensures the leavening and flavors are evenly distributed.
- Beat the eggs and sweetener: In a separate bowl, use an electric mixer to beat the eggs and erythritol until light and fluffy, roughly 3-4 minutes. the volume gives your cake a light crumb despite being flourless.
- Combine wet ingredients: Stir in the melted butter, cooled coffee, and vanilla extract into the egg mixture.
- Fold wet into dry: Gently fold the wet mixture into the dry ingredients with a spatula until just combined. Avoid overmixing to keep the texture tender.
- Transfer batter to pan: Pour the batter into the prepared cake pan, smoothing the top with a spatula. Sprinkle the remaining walnuts evenly over the surface.
- Bake: Place in the oven and bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean with a few moist crumbs attached. the cake should spring back when lightly pressed.
- Cool thoroughly: Let the cake cool in the pan for 15 minutes, then turn out onto a wire rack to cool fully before slicing. This ensures the crumb sets perfectly.
Tips for Success
- Experiment with coffee intensity by adjusting the brewed coffee or espresso powder quantity; a stronger coffee enhances the flavor depth.
- Substitute walnuts with pecans or macadamia nuts for a diffrent yet equally luxurious crunch.
- Use room temperature ingredients to optimize emulsification and batter consistency.
- If mixing sweeteners, blend erythritol with a touch of stevia to balance sweetness profiles without aftertaste.
- Make-ahead option: This cake freezes beautifully wrapped in plastic wrap and stored in an airtight container for up to 2 months. Thaw overnight in the fridge before serving.
- For an extra moist crumb, brush the warm cake lightly with brewed coffee or a sugar-free coffee syrup right after baking.
