A soft vanilla coffee cake baked in a 13 by 9 pan with two buttery layers of cinnamon crumb topping. Easy to make, feeds a crowd, and perfect for brunch, breakfast, or coffee time.
Preheat oven to 350 F. Grease or line a 13 by 9 pan with parchment.
In a medium bowl, whisk together eggs, oil, milk, and vanilla until smooth.
In a separate bowl, whisk flour, sugar, baking powder, and salt.
Fold dry ingredients into wet until just combined. Spread batter evenly in the pan.
For Topping 1, mix softened butter, brown sugar, and cinnamon. Crumble evenly over the batter.
For Topping 2, cut butter into brown sugar, flour, and cinnamon until crumbly. Sprinkle evenly over Topping 1.
Bake for 40 to 50 minutes, until edges are golden, the center springs back lightly, and a toothpick comes out mostly clean.
Cool for 15 minutes before slicing into squares.
Notes
Family favorite: This coffee cake is a weekend tradition in our house. It is simple to make, feeds a crowd, and always disappears quickly.
Serving suggestions: Pair with fresh berries and hot coffee for breakfast, or drizzle a glaze and serve with ice cream for dessert.
Make ahead: Bake the night before, cover tightly, and rewarm slices in a low oven for 5 minutes to refresh the crumb topping.
Storage tips: Store at room temperature up to 2 days, refrigerate up to 5 days, or freeze for 2 months. Wrap slices individually for easy weekday treats.
Variations: Add apples or blueberries for a fruity twist, swap almond extract for vanilla, or drizzle melted chocolate before adding crumbs for a dessert-style version.
SEO reinforcement: This two-layer coffee cake is also known as a crumb cake because of its thick buttery topping. Whether you call it a coffee cake or a crumb cake, it is perfect for brunch, church potlucks, or cozy mornings at home.
