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.

🔪 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.

Common Questions
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.
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.
Yes, you can add ingredients like chocolate chips, dried fruits, fresh berries, or shredded coconut to customize the recipe to your liking.
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.
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.
While 1 cup of flour weighs 160g in my kitchen, it might weigh anywhere from 120 to 180g in your kitchen and there’s a few reasons for that. The weight of ingredients may vary due to the brand of ingredients, the brand and style (wet vs dry) of measuring cups and spoons, and the technique for measuring into cups: scooping and leveling versus spooning the ingredients into the cup measure. For best results, go by the weight listed in the recipe.Why are the metric weights of your ingredients different than the results of Google and my kitchen scale?
