Can I use yellow squash instead of zucchini in this cake?

Yes, yellow squash is a perfectly acceptable substitute for zucchini as they have nearly identical water content and texture. The skin of the yellow squash is thin enough that it will disappear into the batter just like the zucchini does. Your cake will still be incredibly moist and the flavor of the cocoa and walnuts will remain the dominant features.

Should I peel the zucchini before grating it into the batter?

There is no need to peel the zucchini for this recipe as the skin is very tender and will break down during the 55-minute bake. Keeping the skin on adds a tiny bit of fiber and color to the batter without affecting the flavor. It also saves you time during the prep phase, which is always a bonus when you want to get the cake in the oven quickly.

How should I store this chocolate zucchini cake with walnuts?

This cake stays moist for up to three days when stored in an airtight container at room temperature. Because of the high moisture content from the zucchini, it can become damp if stored in a very warm environment, so a cool spot on the counter is best. You can also refrigerate it for up to five days if you prefer a firmer, fudgy texture when eating.

Can I freeze this cake for later use?

This cake freezes beautifully because of the fat content from the oil and the moisture from the squash. Wrap individual slices or the entire cake tightly in plastic wrap and then a layer of aluminum foil to prevent freezer burn. It will stay fresh in the freezer for up to three months, and you can thaw it at room temperature for a few hours before serving.

What if my walnuts are turning too dark during the bake?

If you notice the walnuts on top are browning too quickly before the center of the cake is done, loosely tent the pan with aluminum foil. This will reflect the direct heat and allow the interior to finish baking without burning the toppings. Make sure the foil isn't touching the batter, or it might stick to the melting chocolate chips.

Can I make this recipe as muffins instead of a 9x13 cake?

You can definitely turn this batter into muffins, though the baking time will need to be reduced to approximately 20-25 minutes. Fill your muffin liners about three-quarters full and sprinkle the chips and walnuts on top of each one. Check them with a toothpick early to ensure they don't overbake, as the smaller surface area means they will dry out faster than the full cake.

Cook Mode Prevent your screen from going dark

Instructions

Prep and sift. Preheat your oven to 325°F and grease a 9×13 pan. Sift together the flour, baking soda, cocoa, and salt in a bowl.
Cream the base. Using a mixer, combine butter, oil, and sugar on low speed until the mixture is light, fluffy, and the sugar has dissolved.
Integrate the eggs. Add the eggs one at a time, ensuring each is fully incorporated to maintain a stable, glossy emulsion.
Mix the liquids. Whisk the buttermilk and vanilla extract together in a separate measuring cup until fully combined.
Combine with precision. Alternately add the dry sifted ingredients and the buttermilk mixture to the creamed base, beginning and ending with the dry ingredients.
Fold the greens. Stop the mixer and gently stir in the grated zucchini by hand until evenly distributed through the batter.
Top the cake. Pour the batter into the prepared pan and sprinkle the semi-sweet chocolate chips and chopped walnuts evenly across the surface.
The slow bake. Bake for 55 minutes or until a toothpick inserted into the center comes out clean, then cool completely in the pan.

Notes

Toast your walnuts in a dry skillet for 3 to 5 minutes before adding them to the batter to enhance their natural flavor profile.
Measure flour and cocoa by weight using a kitchen scale rather than cups to ensure the delicate balance of moisture and dry ingredients remains intact.
Bring your eggs and buttermilk to room temperature at least an hour before baking to prevent the fats from seizing during the mixing process.
Test the activity of your baking soda by mixing a pinch with vinegar; if it does not bubble immediately, it should be replaced to ensure proper lift.
Leave the skin on the zucchini when grating to preserve valuable nutrients and help manage the moisture content within the cake structure.
