Preheat oven to 350F/180C. Grease and line an 8*4 loaf pan.
In a bowl, sift in the "dry ingredients". Mix together and keep it aside.
In another bowl, toss 3/4 cup tutti frutti in 1 tbsp of all-purpose flour. Coat fully and keep it aside.
Take a bowl. Add softened butter. Beat for 2 minutes. Now, add sugar and beat till light and fluffy. Next, add yogurt, and whisk for a minute.
Add vanilla extract, and lemon zest and mix until combined.
Add the dry ingredients little by little and gently fold them in.
Finally, add milk little by little and mix until all the ingredients are combined.
Now add the tutti frutti coated in all-purpose flour. Gently fold it in the batter.
Pour the batter into the prepared loaf pan.
Top it with 2 more tsp of tutti frutti.
Bake at 350F for 45 to 50 minutes or till a toothpick inserted in the center comes out clean.
Let the cake cool down for 10 minutes. Run a knife around the edges of the cake and remove the cake from the loaf pan. Cut and serve.
