Mix the eggs with the sugar, add mayonnaise, mix well again.

Stir in the resulting mass of condensed milk.

The flour mix well with baking powder and stir into the liquid mass. The dough should get thick but not solid (thicker than for pancakes, for example). Put the dough in a greased form or on the laid paper baking sheet layer with a thickness of about a finger and - in the oven (180 degrees) for 25 minutes. During baking the dough rises.(I have a form of 24 cm, making three layers).

Cooled cakes cut lengthwise and fluff cream (sour cream whipped with sugar). The top layer leave the cream to better lay down the mastic. Leave for 15 minutes to soak.

Meanwhile, cook the paste for any recipe. (I took 2/3 Cup of powdered sugar and milk powder, 2 tbsp condensed milk, 2 tsp lemon juice. Dust and dry. milk to mix, slowly add the condensed milk and juice, mixing first with spoon, then kneading with your hands. If you really stick to adding the powder, if it will turn out too dense - to dilute a few drops lim. juice). Mastic roll out with a rolling pin (sprinkled table powder).

Cake trim at the sides, trying to give the silhouette of the mouse. Part of scraps can be put on the top half of the hump to make it look like a mouse back. (And then over charge the batteries of the camera :( I had lot of to do on the phone).

Mastic, carefully lift (you can collapse it with a lot of pre-powder), put on the cake, gently smooth. The extra down - trim. Blind trimming, make them ears and tails. Eye - prunes, the nose - candied :)

It is desirable to send the mouse in for the night in the fridge for the final impregnation of the layers and drying of the mastic. Bon appetit!!
