Equipment

9x13" pan

Ingredients

For the cake:

1 ⅔ cups all-purpose flour
1 cup (2 sticks) salted butter softened
1 cup sugar
4 large eggs
½ tablespoon real vanilla extract
1 teaspoon baking powder keeps the crumble from sinking into the cake!

For the crumb topping:

1 ½ cups all-purpose flour
14 tablespoons (1 stick + 6 tablespoons) butter softened
1 cup light brown sugar packed
1 tablespoon cinnamon
1 tablespoon real vanilla extract

Instructions

Preheat oven to 325°F. In the bowl of a mixer with a flat beater attachment, add sugar and butter, and cream until whipped in texture, starting the mixer on low and increasing speed to medium. Scrap down the sides of the bowl. Add eggs and vanilla, and mix on low until combined. Add flour and baking powder, and mix on medium-low until just combined, scraping down the sides of the bowl as necessary.
Pour batter into a greased 9x13" glass pan, spreading the batter out as evenly as possible.
For the crumb topping, in a separate medium bowl, add all ingredients (flour, butter, brown sugar, cinnamon, and vanilla extract). Use your hands to pinch together and thoroughly combine ingredients into a course crumble. You can also use a fork or pastry cutter but I find using my hands is the easiest method!
Evenly spread crumb on the top of the cake batter in the pan. Do not push crumb down into batter; just let it sit on top of the batter!
Bake for 37-42 minutes until a toothpick inserted in the middle of the cake comes out with loose crumbs on it (not batter) and the cake looks set.
Let cool for 10 minutes before cutting.

Notes

Store in an airtight container for up to 5 days! I find the cake most delicious when it’s warm, so feel free to pop in the microwave or oven before enjoying!
