Ingredients
Method
- Step 1: Prepare the dry ingredientsIn a large bowl, whisk together flour, caster sugar, brown sugar, baking powder, cinnamon, and nutmeg until everything is well incorporated. Set aside.
- Step 2: Brown the butterIn a small saucepan over medium heat, melt the butter. Continue cooking, swirling occasionally, until the butter turns golden brown and develops a nutty aroma (about 5-7 minutes). You'll see the milk solids settle at the bottom and turn golden. Remove from heat and let cool for 2-3 minutes. Pour into a bowl, being careful not to disturb the sediment at the bottom (though a little is fine).
- Step 3: Prepare the wet mixtureIn another bowl, whisk together the egg, egg yolk, vanilla extract, and milk until well combined.
- Step 4: Combine wet and drySlowly add the warm brown butter to the egg mixture while whisking constantly. Add it gradually (about 4 additions) to prevent the egg from scrambling. Once fully combined, pour this entire mixture into the center of the dry ingredients. Using a rubber spatula, fold gently until just combined—there should be no flour pockets, but don't overmix.
- Step 5: Add peachesFold in the diced peaches gently with soft hands to avoid crushing them.
- Step 6: Prepare the muffin trayGrease a jumbo muffin tray (6-cavity). Divide the batter equally among the muffin cups, filling each about ¾ full.
- Step 7: Make the streusel toppingIn a separate bowl, combine flour, brown sugar, cinnamon, and nutmeg. Add the cold butter and combine using a pastry cutter, two forks, or your fingertips until the mixture resembles coarse breadcrumbs with visible butter pieces.
- Step 8: Top and bakeDivide the streusel mixture evenly over each muffin. Bake in a preheated oven at 170°C (340°F) for 25-30 minutes, until golden brown and a toothpick inserted in the center comes out clean.
- Step 9: Cool and serveCool in the tin for 10 minutes, then use an offset spatula to gently demold the muffins onto a serving plate. Serve warm or at room temperature.
Notes
NOTES:
- Peaches: Use fresh, ripe peaches for the best flavor. If peaches are out of season, canned peaches (drained well) work too, but fresh is ideal.
- Brown butter: Don't skip this step. It's what makes these muffins special. The browning process is crucial for flavor development.
- Dicing vs. cutting: Dice the peaches into small, even pieces so they distribute evenly and don't sink to the bottom.
- Jumbo vs. regular muffins: This recipe is designed for jumbo muffin tins. If using regular muffin tins, reduce baking time to 18-20 minutes and you'll get about 12 muffins.
- Make ahead: The batter can be prepared up to 2 hours ahead, but don't add peaches until just before baking to prevent them from breaking down.
