Ingredients
- 130g (4.6 oz / 1½ cups) gluten-free oat flakes
- 240ml (1 cup / 8 fl oz) hot water
- 2 large eggs
- 30g (2½ tablespoons) natural sweetener (stevia, erythritol, or preferred alternative)
- 1 teaspoon (5ml) vanilla extract
- 120g (½ cup / 4.2 oz) plain Greek yogurt
- 50g (¼ cup / 1.8 oz) butter, melted and cooled
- 1 medium apple, diced
- 80g (2.8 oz / ⅔ cup) fresh blueberries
- 7g (½ tablespoon) baking powder
Instructions
Step 1: Prepare the Oats
Place oat flakes in a large bowl and pour hot water over them. Stir well and let soak for 5 minutes until oats soften and absorb most of the liquid.
Step 2: Mix Wet Ingredients
In a separate bowl, beat eggs with the natural sweetener until well combined. Add vanilla extract, Greek yogurt, and melted butter, mixing until smooth.
Step 3: Combine Oat and Egg Mixtures
Add the wet ingredients to the soaked oats, stirring gently until just combined. Don’t overmix to maintain a tender texture.
Step 4: Prepare the Fruit
Wash and dice the apple into small, uniform pieces. Gently rinse blueberries and pat dry with paper towels.
Step 5: Fold in Fruit and Leavening
Add diced apple, blueberries, and baking powder to the batter. Fold gently to distribute fruit evenly without bursting the blueberries.
Step 6: Prepare Pan
Grease a 20cm x 8cm (8-inch x 3-inch) loaf pan or line with parchment paper for easy removal.
Step 7: Transfer Batter
Pour the batter into the prepared pan, spreading evenly and gently tapping to settle any air bubbles.
Step 8: Bake
Preheat oven to 180°C (356°F). Bake for 50 minutes until the top is golden brown and a toothpick inserted in the center comes out clean or with just a few moist crumbs.
Step 9: Cool Completely
Remove from oven and let cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely before slicing.
Step 10: Serve
Slice and serve at room temperature. Store covered in the refrigerator for up to 5 days.

Why This Oat Cake Supports Healthy Eating Goals
This cake provides sustained energy through complex carbohydrates from oats while keeping refined sugar to a minimum. Blueberries contribute powerful antioxidants that support brain health and reduce inflammation, while apples add natural sweetness plus fiber and vitamin C. The oats provide beta-glucan fiber, which helps maintain stable blood sugar levels and supports heart health. Greek yogurt adds protein and probiotics for digestive wellness. The moderate calorie content and high fiber make this cake satisfying without being overly indulgent, making it suitable for those managing weight or following balanced eating plans while still enjoying occasional treats.
