Refrigerate the crumbles while you prepare the batter.
Preparation of the cake base
Beat softened butter, sugar, vanilla and salt for about 5 minutes until fluffy and creamy.

Do not stir the batter too long, so that the cake base tastes fluffy after baking. Once all the ingredients have just combined to form a homogeneous mass, the batter is ready.
The amount of flour indicated may vary. Add flour in portions to the liquid mixture until a spreadable batter is formed. If the batter is too firm, you can add a dash of milk.
Do not bake the rhubarb crumble cake longer than necessary, so that it tastes moist and not dry. The indicated baking time may be different. Use a wooden skewer to check if the cake is done baking.
