How to make cinnamon cake step by step

Step 1 - preparations

• Preheat the oven to 180℃ (top/bottom heat mode) or 170℃ (fan-assisted).
• Grease the baking pan with butter and dust with flour, or line it with baking paper.
• Peel the apples, cut them into quarters, and remove the core. Cut the fruit into small cubes and mix with cinnamon.
  approx. 300 g apples, 0.5 teaspoon cinnamon
  

Step 2 - How to make the cinnamon dough

• In a large bowl, mix flour, baking powder, and cinnamon.
  250 g all-purpose flour, 2 teaspoon baking powder, 1 teaspoon cinnamon
  
• In a second bowl, mix the remaining ingredients.
  200 g sugar, 120 ml oil, 2 eggs, 120 ml yogurt
  
• Add the wet ingredients to the dry ones.
  
• Mix thoroughly - the batter will be quite thick - if it's too thick and hard to mix, you can add a little milk (I didn't add any).
  
• Spread about half of the batter onto the bottom of the prepared pan.
  
• Place the apples on top of the batter and gently press down.
  
• Layer the rest of the dough over the apples.
  

Step 3 - How to make streusel for the apple cake

• Transfer the streusel ingredients to a bowl and crumble with a fork or your fingers until lumpy.
  70 g all-purpose flour, 50 g sugar, 30 g butter
  
• Sprinkle the streusel over the top of the cake.
  

Step 4 - Baking the cinnamon apple cake

• Place the mold into the hot oven and bake for about 55-60 minutes - until a toothpick comes out clean.
• After baking, let the cake cool.
