For the crunchies, mix 135 g sugar, 175 g flour, 125 g oat flakes in a bowl and add 140 g cold butter. Spread on a baking sheet and bake for 15-20 minutes.

Heat 75 g butter and fry four apples in the butter. Then add 210 g of sugar, 1 tablespoon of cinnamon and 3 tablespoons of apple cider vinegar.

For the cream-yogurt mixture, whip up 500 ml of whipped cream, add 2 tablespoons of vanilla sugar and then fold in the yogurt.

Layer the apples and crunchies in a glass to serve. First fill in the apples, then the crunchies and then the cream and yogurt mixture. Repeat the layers as often as you like.
