This pumpkin streusel coffee cake takes the classic to a new flavorful level. This delicious breakfast or brunch treat is topped with vanilla glaze and chopped pecans.
Preheat the oven to 350°F and line a 9x9 baking pan with parchment paper.
Beat the brown sugar and softened butter together until creamy.
Add the egg and beat until fluffy.
Beat in the pumpkin, combining well.
In a separate bowl, combine the spices and the flour.
Beat in half of the dry mixture into the wet ingredients.
Add in the buttermilk*
Beat in the remaining flour mixture until just combined. Do not overmix.
Spoon the cake batter into the baking pan.
Spread out evenly.
Melt the butter and combine it with the brown sugar, cinnamon, and flour.
Use a fork to rake through the mixture and to make it crumbly. **
Spread evenly over the cake batter.
Bake in the preheated oven for 50-60 minutes. Oven temperatures will vary. Check the center of the cake with a toothpick before removing from the oven.
Allow the cake to completely cool before mixing together the ingredients for the drizzle and adding to the cake.
Notes
*To substitute the buttermilk, combine ½ cup of milk with ½ tablespoon of lemon juice. Allow the mixture to sit for 5 minutes before adding it to the batter.**A trick I use is to place the crumble mixture in the palm of my hands and rub my hands together and allow the crumbs to fall onto the batter. It creates a fine crumble.
