To prepare healthy blueberry oatmeal muffins start heating the oven to 200°C (180° fan), gas 6. Line a 12 hole muffin tin with paper cases.
Sift together both flours, baking powder and bicarbonate of soda into a mixing bowl.
Stir in the rolled oats and sugar.
Whisk together the eggs and honey until smooth.
Add the buttermilk, oil and vanilla and whisk until blended.
Add to the flour mixture and mix until just combined.
The mixture will be lumpy.
Fold in the blueberries.
Spoon into the paper cases and bake for about 20 minutes, until risen and golden.
Cool in the tins for 5 minutes, then place on a wire rack to cool completely.
