These muffins capture summer fruit at its peak. Swap in any berries or stone fruit for the peaches, however the spices here complement peaches the best. The crunchy, sugary topping uses oats for some added texture. —Posie (Harwood) Brien
Preheat the oven to 350 and line a muffin tin with paper liners (ideally makes 12 medium muffins). Grease the top of the tin as the muffins may spill over slightly.
In the bowl of a stand mixer, cream the butter and sugars together until fluffy. Add the eggs, vanilla and milk and mix together. In a separate bowl, whisk together the flour, baking powder, cinnamon and nutmeg.
Add the dry ingredients slowly to the stand mixer, beating until just incorporated. Stir in the peaches gently.
In a small bowl, mix all the streusel topping ingredients together with your fingers until it has a sandy texture.
Spoon the batter into a muffin pan with muffin liners. Fill to the top.
Sprinkle the streusel topping over the batter and bake for 20-25 minutes, until slightly golden.
