Why Choose a No Sugar, No Flour Dessert?
The Benefits of Cutting Out Refined Sugar
Eliminating refined sugar helps stabilize energy levels, improves gut health, and supports weight management. In this recipe, apples provide just the right touch of sweetness, making it satisfying without spiking blood sugar.
The Power of Oats as a Natural Flour Substitute
Rolled oats make an excellent stand-in for traditional flour. They’re naturally gluten-free, high in fiber, and lend a lovely texture to the cake. When baked, oats soak up moisture from the apples and yogurt, creating a soft, melt-in-your-mouth crumb.
Ingredients You’ll Need
This cake relies on a short list of pantry staples:
2 medium apples (grated, with skin)
1 cup rolled oats
2 eggs
½ cup plain unsweetened yogurt
1 tsp ground cinnamon
1 tsp baking powder
½ tsp vanilla extract (optional)
A handful of chopped walnuts (optional, for crunch)
Each ingredient contributes to the cake’s natural flavor and texture. The apples bring sweetness and moisture, oats act as the base, and yogurt keeps everything tender.

Step-by-Step Instructions
1️⃣ Prepare Your Baking Pan
Preheat your oven to 350°F (180°C). Line a loaf pan with parchment paper or lightly grease it to prevent sticking.

4️⃣ Bake to Perfection
Pour the batter into the prepared pan and smooth the top. Bake for 30–35 minutes, or until golden and a toothpick inserted in the center comes out clean.
5️⃣ Cool, Slice, and Enjoy
Let it cool for 10 minutes before slicing. Serve warm or chilled — it tastes amazing either way!
