Why You’ll Love Honey Walnut Oat Cake

When you need a little sweet treat fast, this Honey Walnut Oat Cake is exactly what you’re looking for. It’s healthy and full of good-for-you ingredients. Plus, it literally takes just 5 minutes to 🌀 blend together before baking. This makes just enough for one portion (you can share if you’d like), and you can jazz it up any way you like: add chocolate chips, a scoop of ice cream or fresh 🍓 berries.

How to Prepare

🔥 Preheat the oven to 375°F (190C).

🍯 To a blender, add the rolled oats, an egg, baking powder, honey, unsweetened almond milk, and a dash of cinnamon.

🌀 Blend for 20-30 seconds.

Ingredients for a recipe laid out on a white surface: a bowl of oats, a small bowl of milk, an egg, walnut pieces, a spoonful of cinnamon, a bowl of honey, and a small dish of baking soda.

🔪 Now, use a sharp knife to chop up 4-5 walnuts and then add them to a ramekin or a small baking dish.

♨️ Next, pour the batter over the walnuts and then put the ramekin in the oven.

⏲️ Bake for 30-35 minutes or until set and then let it cool for a few minutes and enjoy.

Nonna’s Tip ❄️

Let this cool before eating. You’ll know it’s ready when there’s no “jiggle“ in the center.

Variations and Substitutions for Honey Walnut Oat Cake

  1. If you are vegan, you are more than welcome to leave out the egg or replace it with 1/4 cup of mashed 🍌 banana. Apple sauce should work as well.
  2. Feel free to leave out the walnuts if you are allergic to nuts.
  3. Berries or 🍫 chocolate chips would be lovely in this Honey Walnut Oat Cake as well.
  4. If you want to triple the recipe or make a big batch of this, you can definitely do so. I have had friends on my page bake it into a small cake instead.

Common Questions

what can I use to make this recipe vegan?

You can try using mashed banana or applesauce instead of the egg. I haven’t tried using a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) or a chia egg (1 tablespoon chia seeds mixed with 3 tablespoons water), but please let me know in the comments if you try this and how it works. Also, to make this vegan, please use maple syrup or agave instead of honey.

Can I use a different sweetener?

Yes, you can use any sweetener of your choice. Honey, maple syrup, agave nectar, or even sugar alternatives like stevia or monk fruit can be used.

What type of milk can I use in this honey walnut oat cake?

Any type of milk can be used, including dairy milk, almond milk, coconut milk, soy milk, or oat milk. I recommend using unsweetened milk in order to make sure the cake doesn’t end up too sweet.

Can I add other ingredients to the batter?

Yes, you can add ingredients like chocolate chips, dried fruits, fresh berries, or shredded coconut to customize the recipe to your liking.

Can I double the recipe?

Yes, you can double or even triple this Honey Walnut Oat Cake recipe. Use a larger baking dish and adjust the baking time if necessary. Ensure the batter is evenly spread out in the dish.

What can I use instead of walnuts?

You can use any type of nuts such as almonds, pecans, or hazelnuts. For a nut-free option, you can use seeds like sunflower seeds or pumpkin seeds.

Hi! I'm Sneji. Nice to meet you!

I am more commonly known as “The Modern Nonna” on social media where I create easy home cooked meals with a modern twist. I was born and raised in Sofia, Bulgaria and learned how to cook at the best culinary school in the world – my grandma’s kitchen. I lived in Greece on the Island of Crete with my parents for a while and then moved to Toronto, Canada when I was in grade 5. I started to really cook and experiment with food 11 years ago when I was 21 years old. Everything I currently know is a reflection of some part of my life…

    1. Hi there,
      Absolutely. So sorry that I didn’t clarify ( I will fix the recipe description as it’s an old one ) I used a small ramekin which is about 6 oz. Ramekins work best for this recipe
