Rich and Sweet Coffee Walnut Loaf Cake

Looking for a delicious and crowd-pleasing sweet morning or afternoon pick-me-up? This coffee and walnut loaf cake is wonderfully moist and tender yet firm enough for slicing, uses only simple ingredients but provides a luxurious, decadent flavor, and is perfect for breakfast, brunch, enjoying alongside rosemary tea or coffee, or as a tasty dessert.

Itโ€™s really simple and easy to prepare, too. All you need is about 10 minutes of prep time. Itโ€™s also fairly adaptable โ€“ whether you want to make it gluten-free, omit or sub the walnuts for other tasty add-ins (like dairy-free chocolate chips or chopped dates), or even swap the glaze for a creamy vegan frosting. You can also easily adapt it to a layered cake, mini loaves, or muffins!

The Ingredients

ingredients for Coffee and Walnut Loaf Cake measured out against a white surface

The Vegan Coffee Loaf Cake:

  • Flax egg: Make an amazing egg replacement perfect for โ€˜bindingโ€™ by combining ground flaxseed (or chia seed) and water.
  • Instant coffee: Or espresso powder. Use a good-quality one for the best flavor.
  • All-purpose flour: Or a 50/50 blend of regular and whole wheat. A gluten-free all-purpose blend like King Arthurโ€™s or Bobโ€™s Red Mill should also work, though it may produce a denser coffee & walnut loaf cake.
  • Brown sugar: The caramel-like flavor complements the coffee loaf wonderfully.
  • Vegan butter: Use your favorite brand, like Miyokoโ€™s or Earth Balance, for the best dairy-free coffee cake. Ensure itโ€™s room temperature.
  • Leavening agents: This vegan coffee cake loaf relies on baking powder and baking soda to provide the required lift and texture.
  • Salt: Just a little to enhance the various flavors in the coffee walnut loaf cake.
  • Vinegar: Use white vinegar or apple cider vinegar. This will activate the baking soda.
  • Oil: Use neutral oil, like vegetable oil. To slightly reduce the amount of oil, you could experiment using unsweetened applesauce (or perhaps vegan Greek yogurt).
  • Walnuts: Use raw, unsalted walnuts. For a nut-free version, you could omit them entirely or use pumpkin seeds/sunflower seeds.

The Coffee Glaze:

  • Instant coffee
  • Powdered sugar: If you donโ€™t have any at home, make your own by grinding it in a spice grinder or high-speed blender (then sift).
  • Water: OR plant-based milk for a creamier glaze.
  • Vanilla extract: Use a natural vanilla extract for the best flavor.

Coffee Walnut Cake Recipe Variations

  • Spices: Several spices complement coffee well, including cinnamon, nutmeg, cardamom, and blends like homemade pumpkin pie spice.
  • Molasses: Just a little deepens the flavor complexity of the coffee walnut cake recipe.
  • Vegan chocolate chips: (or chunks): Use your favorite dairy-free chips/chunks (milk or dark chocolate) to fold into the coffee walnut loaf cake.
  • Shredded coconut: Add a few tablespoons for subtle flavor and extra texture.
  • Caramel sauce: Swirl store-bought or homemade caramel sauce (like our 4-ingredient date caramel) between layers of the loaf batter.
  • Nut butter: Swirl it into the top of the vegan coffee loaf before baking.
  • Dried fruit: Like raisins, dates, cranberries – for extra sweetness and chewiness.
  • Orange: Add the zest of one orange for a subtle citrusy flavor and brightness.
  • Streusel topping: Replace the glaze with a crisp crumble topping.

How to Make Coffee and Walnut Loaf Cake?

  • 1) First, preheat the oven to 350F/175C and lightly grease a loaf pan.
  • 2) Then, combine the flax meal and water in a small bowl, mix thoroughly, and set it aside for 5 minutes to thicken. Also, combine the instant coffee and water (warm).
  • 3) Then, in a large mixing bowl, using an electric mixer, cream the vegan butter and sugar until light and fluffy.

This step helps make a fluffy, moist vegan cake, so cream it well. It should be pale and fluffy when ready.

  • 4) Add the remaining vegan coffee loaf ingredients (except the walnuts) and mix it into a batter.

Be careful not to over-mix it, though, or it can overwork the gluten in the flour and lead to a dense, tough loaf.

  • 5) Next, fold a cup of walnuts into the vegan coffee loaf batter and pour it into the prepared loaf pan. Bake it in the oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean (or with a few moist crumbs).
  • 6) Remove the coffee walnut loaf cake from the oven and transfer it to a wire cooling rack to cool completely (we prefer to leave it in the pan for 15 minutes before removing it). Once cool, prepare the coffee glaze by combining all the ingredients and mixing well.
  • 7) Finally, spread the glaze over the coffee loaf cake and sprinkle with a tablespoon of walnuts to finish โ€“ enjoy!

Enjoy a slice alone, warm and slathered in vegan butter or nut butter, with vegan whipped cream, a scoop of vegan ice cream (vanilla or coffee flavored), and as a part of a delicious brunch, afternoon tea, or dessert spread!

FAQs

Can I make a vegan, gluten-free coffee loaf cake?

An all-purpose gluten-free flour blend like King Arthurโ€™s or Bobโ€™s Red Mill may work using a 1:1 ratio- though may be denser and/or slightly drier. Avoid using single flours, like almond flour or coconut flour, as other changes would be needed.

Can I use this recipe for baking vegan coffee walnut muffins?

Absolutely โ€“ though the baking time will need to be reduced. Somewhere around 17-20 minutes should work well, but make sure to test its doneness with a toothpick.

Can I make this into mini loaves?

To make mini coffee walnut loaves, divide the batter into several smaller loaf pans and reduce the baking time (first check at about 20 minutes). Use a toothpick to test for doneness. The baking time will vary based on the loaf pan size.

Can I make a vegan layered coffee cake?

This recipe will probably be okay for a 6-7 inch two-layered cake. For a larger one, double the ingredients first. Optionally top it with a creamy vegan coffee buttercream rather than the glaze.

Top Recipe Tips and Notes

  • Use high-quality ingredients: Use high-quality coffee you like the flavor of, good walnuts, and natural vanilla extract for the best flavor.
  • Measure the flour correctly: Fluff it up in its bag, spoon it into the measuring cup, and level it with the back of a knife. Too much flour leads to dry, dense bakes.
  • Donโ€™t over-mix the batter: You could overwork the gluten and end up with a dense, dry coffee loaf.
  • For a stronger coffee flavor: Dissolve more instant coffee/espresso into the water for a stronger brew.
  • It tastes even better on day two: So, if you have the patience, leaving it is a great idea. Otherwise, make enough for leftovers.

Storage Instructions

Once baked, store the cooled coffee and walnut loaf cake in an airtight container on the countertop for 2-3 days or in the refrigerator for 5-7 days. The flavors of the loaf only improve overnight, so weโ€™re a big fan of making enough for leftovers.

You can also freeze it for up to 3 months, whole or sliced with parchment paper between the slices (best done without the glaze topping). Wrap it in plastic wrap and place it in a Ziplock/Stasher bag to avoid freezer burn.

When you want a slice, leave it to thaw at room temperature or defrost it in a toaster oven or microwave.

    I love coffee and had a bunch of walnuts I wanted to use. The recipe was easy to make with things I already had in my pantry. I did use apple sauce in place of oil. The bitter-sweet combination is perfect.
