Brown Butter Apple Streusel Bread

Preheat oven to 375°F (190°C). Line a 9x5-inch loaf pan with parchment paper and set aside.
In a small saucepan, brown the butter over medium heat until golden brown with a nutty aroma. Watch the butter carefully, as it can easily go from browned to burnt! Set aside to cool.
If you wish to peel the apples, do so before chopping. Chop apples into small pieces and set aside.
In a bowl, combine brown sugar, cinnamon, and flour. Cut in the very cold butter until mixture is crumbly. I use a cheese grater to easily grate the butter. Set aside.
In a large bowl, whisk together flour, baking powder, salt, and cinnamon. In a separate bowl, whisk the browned butter, sugar, eggs, Greek yogurt, and vanilla until smooth. Fold the wet ingredients into the dry, then gently fold in chopped apples.
Pour half the batter into the prepared loaf pan, then sprinkle with half the crumble topping. Add the remaining batter on top, followed by the rest of the crumble. Bake for 55–60 minutes, or until a toothpick comes out clean.
Once bread has cooled, whisk together powdered sugar and heavy cream. Drizzle over the loaf before slicing and serving.
