A rich and decadent espresso crumb cake recipe, perfect for coffee lovers. This recipe features a moist cake base infused with the bold flavor of espresso, topped with a crunchy, buttery crumb topping.
Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
In a large bowl, whisk together flour, granulated sugar, baking powder, baking soda, and salt.
In a separate bowl, cream together the butter and brown sugar until light and fluffy. Beat in the eggs one at a time, then stir in the buttermilk and espresso powder.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Pour batter into the prepared pan and bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
Let cool completely before serving.
Notes
For a richer flavor, use freshly brewed espresso instead of espresso powder.
