Appleless Apple Cake

I was pretty nervous to try this out. but it turned out great! the cake batter had a fudgy quality to it. the the mock apples did taste like apples! I made this in a 13by9 flat pan so it was more like a apple cake bar. Could probably be made in a 8by8 pan too.

50g four (atta)
23-25g chickpea flour
245g fresh pumpkin-microwave then pureed
2 egg whites-whipped to peaks
1/2 tsp stevia
-mock apples( recipe below)
-combine flours and stevis, then fold in pumkin, then the peaked whites
-fold in some baking powder
-add some water to thin out the batter
-spread about 1/3 of batter on the lined pan
-top with "apple" slices-make only 1 layer
-top with remaining batter
-bake at 170d.Celsius for 40 minutes

Mock Apples
250-300g chayote
4 tsp sugar equivalent
green apple essence/extract
-slice chayote into 0.25-0.4cm thin slices
