Ingredients

Topping

1/2 cup flour
1/2 cup granulated sugar
1/2 cup brown sugar
1 tsp cinnamon
4 Tbsp butter, melted
2/3 cup chopped pecans (optional)

Cake

1 1/2 cups sifted all-purpose flour
2 1/2 tsp baking powder
1/2 tsp salt
1 egg, beaten
3/4 cup sugar
1/3 cup melted butter
1/2 cup milk
1 tsp vanilla extract

Directions

In a small mixing bowl, combine all topping ingredients. Blend with fork until crumbly and set aside.
Preheat oven to 375° F (190° C).
Sift 1 1/2 cups sifted flour with baking powder and salt into a bowl
In a medium bowl, beat together beaten egg and 3/4 cup sugar wth 1/3 cup melted butter. Add in vanilla.
Switch off between adding in the flour mixture and milk to keep mixture from getting too dry or too wet to combine properly.
Once the batter is all mixed in, pour into a greased and floured 8-inch square pan. Sprinkle the topping evenly over the batter, using your fingers if needed to sprinkle the thicker pieces.
Bake at 375° F (190° C) for 25-30 minutes, checking if the cake is done with toothpick insertion.
Enjoy! :)

The crumbly topping is insane! I've never been able to get the texture as thick and crispy—it's so buttery and rich too!

The topping was a bit too thick for my liking. If I make this recipe again, I think I'll be cutting the amount of butter and sugar in half because it was just way too sweet.

Super yummy! I did cut down the amount of sugar a bit, and thinned down the topping a little because it just seemed too heavy. But even with those changes, I really enjoyed the cake and will be making it again soon——maybe with blueberries!
