Apple & Walnut Oat Cups (vegan, gluten-free option, sugar-free)

I’m not much of a baker, but when I do occasionally bake, I love recipes that are simple, quick, and packed with nutrition — like these apple & walnut oat cups. They’re naturally sweetened with dates, apple, and a touch of cinnamon, so there’s no refined sugar, and they’re completely vegan and gluten-free (if you use gluten-free oats).

Each oat cup has 8.5g of protein, 5.5g of fibre, and plenty of healthy fats from walnuts and peanut butter, making them nourishing and satisfying. The rolled oats provide slow-releasing energy, while the protein and healthy fats help keep you full and fuel your day. Plus, the walnuts add vitamin E, magnesium, and omega-3s, making these cups a truly nutrient-packed snack or breakfast. Perfect for snack prep, breakfast on the go, or a healthy sweet treat, they’re both delicious and nourishing.

Ingredients Method Notes

Ingredients

  

Wet ingredients (for blending)

• 4 Medjool dates pitted
• 1 cup unsweetened soy milk
• 3 tbsp peanut butter
• 1 tsp vanilla extract

Dry & mix-in ingredients

• 1.5 cups rolled oats
• 1/3 cup almond flour
• 1 tbsp ground flaxseed
• 1 tsp cinnamon
• 3/4 tsp baking powder
• Pinch of salt

• 1 medium red apple grated

Method

 

1. Preheat oven to 175°C and grease a silicone or non-stick muffin tray with a little oil or butter.
2. Blend the wet ingredients in a blender until smooth. A few lumps are fine – they add chewy texture.
3. In a bowl, combine the oats, almond flour, flaxseed, cinnamon, baking powder, salt, and walnuts. Add the grated apple and blended wet mixture, and mix until fully combined.
4. Spoon the batter evenly into the 6 muffin cups, flatten slightly with the back of a spoon, and top with extra walnuts.
5. Bake for 20-25 minutes, until golden on top.
6. Allow to cool before removing from the tray. You may need a knife to loosen the edges.
7. Serve and enjoy as a quick breakfast, healthy snack, or sweet treat!
