Preheat the oven to 350 degrees Fahrenheit

Grease a 9 in round Springform Pan

Slice and Pit the Plums... set them aside... if the plums are BIG... you can cut them into fourths, otherwise go with halves.

In a mixing bowl, cream the butter and sugar until light and fluffy... about 5 minutes.

Add the grated Lemon Peel... beat, and scrape down the sides.

Add the eggs one at a time. Beat and scrape between eggs.

Add the Baking Powder to the Flour in a mixing bowl, then slowly (unless you really want to wear it) add the flour mix to the butter mixture.

Scrape down.. and mix again

When mixed (you don't need to overmix) spread the batter into the prepared pan. Now... this can be a bit fiddly. I found it easiest to start with a spatula, then I rub my hands with the residue on the butter wrapper and press the dough to the edges.

Sprinkle the dough with a few teaspoons of Vanilla Pudding Powder.

Shingle the Plums onto the batter... then sprinkle them with a few more teaspoons of Vanilla Pudding Powder.

Mix the Streusel

Cut the butter into small cubes.

Put the flour and sugar into a bowl... drop in the butter cubes... rub the butter and flour mix with your fingers until it looks like crumbs. When you put the streusel on cake or muffins... squeeze it a bit in your fist to get a bigger crumb.

Bake

Bake for 50 -55 minutes... the streusel should be browning.

Take from oven ...

Let cool on Cooling Rack
