Apple and Pumpkin Spice Cake

I've been eyeing this recipe for a while and have been dying to make it eversince I found it.  Since I'm just a beginner baker I still don't have a springform pan and wanted to make a smaller cake anyway because it was only for a small thanksgiving.  I found a pumpkin spice cake recipe in my Better Homes and Garden cookbook that sounded very flavorful and worthy to make.  The recipe called for baking it in two 8in pans or one 13*9in pan but I didn't need that much, so I divded the recipe in half and baked it in one 8in pan.  I also decided to add the apple streusel topping from the Zoe Bakes website on top of my half version pumpkin cake rather than a frosting. 

The cake worked out great, the apple cinnamon combination blended well with the moist spiced pumpkin bottom.  I served it with ice cream and the four of us almost finished the whole cake, we all ended up having seconds!  Below I've posted my altered half version for you to try because it worked out so well.
