This Cinnamon Streusel Coffee Cake is a delightful treat perfect for breakfast or as a sweet snack.
Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
Ensure the oven is fully preheated for even baking.
In a mixing bowl, combine the flour, sugar, and baking soda. Add the butter and mix until crumbly.
Use cold butter for a crumbly texture.
Add the eggs, sour cream, and vanilla to the dry mixture and mix until smooth.
Mix just until combined to avoid overmixing.
Pour the batter into the prepared pan and spread evenly.
Tap the pan gently to remove air bubbles.
In a separate bowl, mix the brown sugar, cinnamon, chopped pecans, and flour. Cut in the cold butter until crumbly.
Use a fork or pastry cutter for the best texture.
Sprinkle the streusel mixture evenly over the cake batter.
Ensure an even layer for consistent flavor.
Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Check the cake at 25 minutes to avoid overbaking.
Allow the cake to cool in the pan before slicing and serving.
Cooling helps the cake set and makes slicing easier.
