Equipment

large mixing bowl
whisk
spatula
8x8 or 9x9 Pan

Ingredients

For the Cake

2 small bananas mashed
2 large eggs
100 g light brown sugar ½ cup
100 g granulated sugar ½ cup
½ cup avocado oil 80mL
1 cup whole milk
1 teaspoon Vanilla extract
256 g AP flour 2 cups
1 teaspoon baking powder
½ teaspoon baking soda
pinch salt

For the Streusel Topping

1 cup all purpose flour
½ cup cane sugar
½ cup light brown sugar
6 tablespoon butter melted
1 teaspoon cinnamon

Instructions

In a large bowl, mash the two bananas using a fork and crack in the two eggs, then whisk until pale and fluffy.
To the eggs and mashed banana, pour in the oil, milk, vanilla, and sugar. Whisk the wet ingredients together until the oil and sugars are well blended.
Preheat the oven to 350º. Pour the dry ingredients into the wet and fold in with a spatula to incorporate the flour until just combined. Let the batter sit on the counter for 20 minutes, then pour into a greased 8x8 or 9x9 pan.
Mix together melted butter, brown sugar, granulated sugar, cinnamon, and flour until it forms a crumbly mixture. Chill in the fridge for up to 30 minutes, then once the batter is done resting, cover the top of the crumb cake and bake for 30-35 minutes. Let cool 5-10 minutes before serving.

Notes

Be gentle when making the batter. I've tested my coffee cake recipe several times, and had to discard or retry a few of those tests because I severely over-mixed the batter. Over-mixing works the gluten too much causing a gummy texture and loss of flavor.

Use room temperature ingredients like eggs and milk so that it blends easier together and doesn't clump.

Mash the bananas in its own banana peel before adding to the bowl as this is a more efficient way of mashing the bananas, then add it to the bowl and mix together with the eggs first, THEN add in the sugar and other ingredients. I've found that this process yields very fluffy cake texture.
