Warm, cozy flavor – Dates lend a caramel-like sweetness, walnuts add toasty crunch, and the spice blend gives a gentle warmth. The aroma while baking is irresistible.

Versatile for any time of day – Enjoy a warm slice with butter for breakfast, pair it with tea for an afternoon snack, or serve it as a simple dessert. It’s equally good fresh or toasted.

Moist, tender crumb – Soaked dates, melted butter, and sourdough starter combine to produce a soft, stable crumb that stays moist for days.

You can also make bite-sized versions of this flavor profile with cookies that pair dates and walnuts for snacking.

Ingredients

• Dates – Use dried, pitted dates. Soaking them softens the fruit and releases natural sweetness. Medjool or Deglet Noor both work well.
• Hot water and baking soda – Hot water helps soften the dates and the baking soda encourages them to break down, creating a smooth, moist addition to the batter.
• Butter – Melted butter adds richness. Salted or unsalted works; if using salted, taste the batter before adding extra salt elsewhere.
• Brown sugar – Brown sugar contributes sweetness and a hint of molasses that complements dates and spices.
• Eggs – Use large eggs at room temperature for best mixing and structure.
• Vanilla extract – Adds aroma and rounds the flavors.
• Sourdough starter – Use active starter or discard; it provides a subtle tang and moisture to the loaf.
• All-purpose flour – The base of the cake structure.
• Baking powder – Gives the loaf a light lift.
• Warm spices – Cinnamon, ground ginger, nutmeg, and allspice create a cozy, lightly spiced profile.
• Walnuts – Roughly chopped walnuts add texture. Lightly toasting them first intensifies their flavor if you prefer.

How to Make Sourdough Date and Walnut Loaf Cake

1. Roughly chop the dates and place them in a bowl with hot water and the baking soda. Use water that has recently boiled. Let the mixture sit for about 10 minutes so the dates soften and the flavors meld while you prepare other ingredients.

2. Preheat the oven to 180ºC (350ºF). Line a small loaf pan (about 1 pound or 8.5″ x 4.5″ x 2.75″) with baking paper and lightly grease to prevent sticking.

3. In a large bowl, whisk together the melted butter, brown sugar, eggs, and vanilla until smooth and glossy; the mixture will resemble runny caramel. Whisk in the sourdough starter until combined, then set aside.

4. In a separate bowl combine the all-purpose flour, baking powder, cinnamon, ginger, nutmeg, allspice, and chopped walnuts. Mix until evenly distributed.

5. Add the soaked dates along with their soaking liquid to the butter and sugar mixture. Then fold in the flour and walnut mixture until you have an even cake batter. Stir gently—overmixing can make a denser crumb.

6. Pour the batter into the prepared loaf pan and smooth the top. Bake at 180ºC (350ºF) for 45 to 50 minutes, or until a skewer inserted into the center comes out clean or with a few moist crumbs attached. Allow the loaf to cool in the pan for 10–15 minutes, then remove and cool on a wire rack.

How to Store and Freeze

Store at room temperature – Keep the loaf in an airtight container or wrapped in baking paper inside a tin or glass container for 3–4 days. This helps retain a soft crumb without becoming overly sticky.

Refrigerate – If your kitchen is warm or you want the loaf to last longer, refrigerate for up to 5 days. Bring slices to room temperature before serving for best texture.

Freeze for later – Once completely cool, wrap the whole loaf or individual slices tightly in plastic wrap and place in a freezer-safe bag or container. Freeze up to 3 months. Thaw at room temperature or warm slices briefly in a toaster or microwave.
