Brown Butter Blueberry Coffee Cake with Streusel Topping

Experience the joy of baking with this recipe that brings out the nutty richness of brown butter and the delightful burst of blueberries in a classic coffee cake.

Ingredients:

• 1/2 cup unsalted butter
• 1 3/4 cups all-purpose flour
• 1 1/2 tsp baking powder
• 3/4 cup coconut sugar
• A pinch of salt
• 1 tsp ground cinnamon
• 2 tsp vanilla extract
• 1 large egg
• 1 egg yolk
• 1 cup milk (any kind)
• 1.5 cups fresh blueberries

For the Streusel Topping:

• 1/4 cup butter, softened
• 3 tbsp dark brown sugar
• 1/3 cup all-purpose flour
• 1 tsp ground cinnamon

Instructions:

1. Begin by preheating your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and lightly grease it to prevent sticking.
2. Prepare the streusel topping in a bowl by whisking together the flour, dark brown sugar, and cinnamon. Mix in the softened butter until the mixture resembles coarse crumbs. Chill it in the refrigerator to keep it firm.
3. For the brown butter, melt the butter in a saucepan over medium heat until it turns a lovely golden brown with a nutty aroma. Remove from heat and allow it to cool slightly.
4. In a large mixing bowl, combine the milk, whole egg, extra yolk, and vanilla extract using a hand mixer. Add the cooled brown butter and mix well.
5. In another bowl, sift together the flour, baking powder, coconut sugar, salt, and cinnamon. Gradually add these dry ingredients to the wet mixture, mixing until just combined to avoid overmixing.
6. Gently fold in the fresh blueberries, being careful not to burst them to prevent the batter from turning purple.
7. Pour the batter into the prepared pan, spreading it evenly with a spatula.
8. Retrieve the streusel from the fridge and sprinkle it evenly over the top of the batter.
9. Bake the cake for 45-50 minutes, or until a toothpick inserted into the center comes out clean.
10. Allow the cake to cool in the pan before slicing. Serve the brown butter blueberry coffee cake warm or at room temperature, perhaps with a dollop of whipped cream or a scoop of ice cream for an added indulgence.

Enjoy this cake with your favorite coffee or tea, and savor the way the flavors blend beautifully – the brown butter lending a deep, rich taste and the blueberries adding a touch of sweetness.
