Ingredients You Need

• Flour – Any all-purpose or gluten-free flour mix works; grain-free options like cassava or arrowroot will also work.
• Sugar – Any granulated sugar can be used; maple sugar or coconut sugar are good alternatives.
• Oil – Neutral oil (avocado, grape-seed, or similar) replaces butter for moisture.
• Honey – A small amount adds scent and extra depth of flavor.
• Baking soda – Enhances the cake’s lift; you can substitute baking powder if needed.
• Salt – Balances and enhances flavor.

How To Make This Walnut Cake: Step-by-Step

Prepare a 9×13-inch pan or a 9-inch square pan and grease it with a little oil. Preheat the oven to 300°F (150°C).

Step 1. Prepare the dry ingredients:

• Pulse the walnuts in a food processor until you reach a flour-like consistency. Be careful not to over-process, or you’ll make walnut butter.
• Combine the ground walnuts with the flour, salt, and baking soda in a bowl and whisk to blend. Set aside.

Step 2. Prepare the wet ingredients:

• In a large bowl, add room-temperature eggs and the sugar.
• Beat the eggs and sugar with an electric mixer until light and thickened, about five minutes.
• Stir in the oil and honey until just combined.

Step 3. Combine wet and dry:

• Pour the walnut-flour mixture over the whipped eggs.
• Add half the dry mixture and fold gently with a spatula until mostly incorporated, then add the rest and fold until homogeneous.

Step 4. Bake the walnut cake:

• Pour the batter into the prepared pan and smooth the top. Optionally sprinkle crushed nuts or seeds over the surface.
• Bake for 55–60 minutes, or until a toothpick inserted into the center comes out clean.
• Remove from the oven and transfer the pan to a rack to cool.

Step 5. Serve:

• When completely cool, run a thin knife around the edges and remove the cake from the pan.
• Dust with powdered sugar if desired, then cut into squares or rectangles and serve.

Recipe Variations & Substitutions

• Cinnamon walnut cake – Add 1 tsp cinnamon and 1/2 tsp cardamom for warm spice notes.
• Coffee walnut cake – Stir in 2 tsp instant coffee or espresso powder for a coffee-kissed version.
• Chocolate walnut cake – Replace 2 tablespoons of flour with 2 tablespoons cacao powder and consider adding coffee to enhance chocolate flavor. Melted chocolate drizzled on top also works well.
• Banana walnut cake – Replace three eggs with two large mashed bananas.
• Apple or carrot walnut cake – Fold in one medium grated apple or two grated carrots for added moisture and flavor.
• With dried fruit – Add chopped dates, raisins, or cranberries; soak them briefly in warm water before folding in.

Storing Tips

• Leftovers: Keep wrapped at room temperature for up to 3 days or refrigerate up to one week. The cake often tastes best on day two or three.
• Freezing: Slice and separate pieces with parchment before freezing in an airtight container for up to 3 months.
• Thawing: Defrost slowly in the refrigerator for 24 hours, then bring to room temperature before serving.
• Reheating: Reheat from frozen in the oven for 15–20 minutes at medium temperature, or from the fridge covered with foil for 10–25 minutes.
