👩🍳 How to Make It (Step-by-step)
✔️ Step 1 – Prep the oven
Preheat to 180°C (350°F). Line a loaf tin or round pan with parchment paper.
💡 Tip: Lightly grease the paper to prevent sticking.
✔️ Step 2 – Mix dry ingredients
Combine oat flour, baking powder, cinnamon, and salt in a bowl.
💡 Tip: Sift for an extra-light texture.
✔️ Step 3 – Combine wet ingredients
In another bowl, whisk eggs, yogurt, honey, and vanilla until smooth.
💡 Secret: Room-temperature ingredients blend better.
✔️ Step 4 – Fold together
Add dry ingredients into wet and mix gently. The batter should be thick but pourable.
💡 Trick: Don’t overmix — the cake stays softer.
✔️ Step 5 – Add blueberries
Fold in the blueberries and lemon zest.
💡 Tip: Toss blueberries in a teaspoon of oat flour to prevent sinking.
✔️ Step 6 – Bake
Pour the batter into the pan and bake for 35–40 minutes.
💡 Test: A toothpick should come out clean from the centre.
✔️ Step 7 – Cool & glaze
Let it cool before adding the yogurt-honey glaze.
💡 Bonus: Garnish with fresh berries and a sprinkle of lemon zest for a café-style look.
