Why it’s worth baking

• Only sweetened using whole dates — no refined sugars involved. If you want another naturally sweet treat, try Three Ingredient Date Cookies.
• Made with oat flour, which adds fiber and gently lowers the glycemic load compared to white flour.
• Vegan and dairy-free as it stands, and super simple to adapt to gluten-free by using certified gluten-free oats.
• Moist and rich thanks to the natural date paste, tahini, and a touch of oil — indulgent feel, without heaviness.
• Uses everyday ingredients you likely already have and bakes easily in a single 8×8 inch tray. For a similar one-pan oat bake, see Banana Peanut Butter Oatmeal Bars.

Ingredients and pantry staples

• 220g soft dates
• 320ml milk of choice (dairy or plant-based)
• 4 tbsp tahini (plus 2 tbsp extra for the drizzle)
• 4 tbsp neutral oil
• 150g oat flour (to make your own, blitz rolled oats in a blender until fine)
• 2 tsp baking powder
• 2 tsp cinnamon
• 1/2 tsp salt
• 40g walnuts, roughly chopped (optional but adds a lovely crunch)
• 2 tbsp tahini
• 1 tsp date syrup

Step-by-step baking method

1. Preheat oven to 180°C (160°C fan) / 350°F and line an 8×8 inch (20×20 cm) square baking tin with parchment paper, leaving an overhang.
2. If making your own oat flour, blitz rolled oats in a blender or food processor until fine and measure after blending.
3. Warm 320ml milk in a saucepan until tiny bubbles form around the edges, then remove from heat just before it boils.
4. Place 220g soft dates in a heatproof bowl and pour the hot milk over them; soak for about 30 minutes (soak longer if dates are dry).
5. Transfer the soaked dates and milk to a blender or food processor and blend until smooth and creamy to form a thick date paste.

6. Pour the date paste into a large mixing bowl and stir in 4 tbsp tahini and 4 tbsp neutral oil until well combined and silky.

   

7. Add 150g oat flour, 2 tsp baking powder, 2 tsp cinnamon, and 1/2 tsp salt to the bowl and mix just until the batter is smooth and uniform (do not over-mix).
8. Pour the batter into the prepared tin, smooth the top evenly, and scatter 40g roughly chopped walnuts over the surface.
9. Bake for 40–45 minutes, beginning to check at 40 minutes; insert a toothpick or skewer into the center — it should come out clean or with a few moist crumbs.
10. Allow the cake to cool completely in the tin until set.
11. Whisk together 2 tbsp tahini and 1 tsp date syrup to make the drizzle.
12. Drizzle the tahini-date drizzle over the cooled cake before slicing.

Pro tips for perfect results

• Try to use soft, moist dates when you can — they blend up smoother and add natural sweetness. If your dates are on the drier side, soak them longer or add a splash more milk when blending to get a nice paste. For a step-by-step example of softening and blending dates into batter, see the Easy Moist Date Cake.
• You can make oat flour yourself by blitzing rolled oats in a blender until fine. Just remember to measure after blending for accurate amounts.
• Mix your batter gently and stop as soon as everything’s combined. Overworking the batter can make the cake tough instead of tender.
• Start checking your cake around the 40-minute mark. If you see wet batter sticking to your skewer, pop it back in and check every few minutes until it’s done.
• Don’t forget to line your pan with parchment and leave an overhang. It makes lifting the cake out super simple without risking breakage.
• Patience is key once it comes out of the oven — let it cool fully in the tin to firm up. A warm cake is more crumbly and trickier to cut cleanly.

Flavor swaps and add-ins

• If you need it nut-free, feel free to skip the walnuts or swap them out for pumpkin seeds — they add a lovely crunch and are allergy friendly.
• Want a different nutty twist? Swap the tahini for peanut butter or almond butter. Your cake remains vegan and gains a new dimension of flavor.
• For a fresh citrus brightness, stir in 1 teaspoon of orange zest—it pairs beautifully with the dates and walnuts. For more citrus-in-bread inspiration, try this orange cranberry bread with a simple glaze.
• If you’re craving chocolate, throw in 50 to 75 grams of dark chocolate chips for a lush chocolate–date combo—similar to these Almond Joy stuffed dates.
• This batter works well for muffins or a loaf too. Just adjust the bake time — muffins take about 18 to 22 minutes, so keep an eye and test with a skewer. For a loaf, expect longer baking and test accordingly.
• For a richer, deeper flavor, try swapping the milk for strong brewed coffee. Just keep in mind that won’t work if you’re avoiding dairy or nut milks.

Storing and reheating advice

Keep your cooled date and walnut cake stored in an airtight container at room temperature, and it’ll stay fresh for up to three days. If you want it to last a bit longer, pop it in the fridge where it will keep nicely for 5 to 7 days. This cake freezes beautifully — wrap slices or the whole thing tightly in plastic wrap or foil, then freezer bag it for up to 3 months; for another fruit-forward bake that freezes well, try Dried Fruit Bread (No Added Sugar, 10-Min Prep). To enjoy, thaw overnight in the fridge or at room temp, then gently warm individual slices in the microwave for 10–20 seconds or heat in a low oven if you like your cake cozy and warm — this quick-warm method also works well for Coffee Cake Muffins.

Common questions answered

• Can I use dry dates? Absolutely! If your dates are on the dry side, soak them for 45 to 60 minutes in hot milk, or gently simmer them until soft before blending. This helps you get that nice smooth date paste.
• Is this recipe vegan? Yes, it is. There are no eggs or dairy in the recipe as long as you choose plant-based milk. Perfect if you’re vegan or dairy-free.
• How do I make oat flour? Easy — just blitz rolled oats in a blender or food processor until they become a fine flour. For best results, measure your oat flour after blending.
• Can I reduce the oil? You can cut down the oil a little, but some fat (like oil or tahini) is vital for keeping this cake moist and tender. Too little oil will make your cake dry and crumbly.
• Can I make this gluten-free? Yes! Use certified gluten-free oats, and double-check that any extra ingredients, like date syrup, are gluten-free too. If you’d like another gluten-free walnut treat, try our Coffee and Walnut Cookies (Gluten Free, Paleo).
• What if I don’t have tahini? No worries. Just swap equal amounts with peanut butter, almond butter, or a bit more neutral oil. The flavor and texture will shift slightly, but it still tastes great.
• Can I change the pan size? Yes, you can use different pans like a loaf or round tin. Just remember baking times will vary — muffins bake faster (check at 18–22 minutes), loaf cake takes longer, so watch closely and test with a skewer for doneness.
