pumpkin pie, anyone?

I'm new here and love pumpkin. I can't wait to try these recipes. I do have a question though. What does "bump" mean?

Found this recipe today on http://m.wholefoodsmarket.com/
I substituted the butter for 1 large banana, mashed. I also used oat flour in place of the whole wheat flour and subed organic agave for the sugar. I also used fresh cranberries. These turned out great, I made 22 large cookies at 70 calories

Makes about 3 dozen cookies
Pumpkin and cranberries make a delicious fall pairing in this chunky oatmeal cookie.

Ingredients
2 cups old-fashioned rolled oats
1 cup whole wheat pastry flour
1 tablespoon pumpkin pie spice
1 teaspoon baking powder
1/2 teaspoon sea salt
10 tablespoons unsalted butter (1 stick plus 2 tablespoons), softened
2/3 cup packed brown sugar
1 1/2 cups canned pumpkin purée
2 large eggs
1 teaspoon pure vanilla extract
1 1/2 cups dried cranberries

Method
Preheat oven to 375°F. Line 2 baking sheets with parchment paper.

In a medium bowl, stir together oats, flour, pumpkin pie spice, baking powder and salt. In a separate bowl, use an electric mixer to beat butter and sugar until light and fluffy, about 3 minutes. Add pumpkin, eggs and vanilla and beat until combined. Stir in flour mixture until just combined, and then fold in cranberries.

Drop cookies by heaping tablespoon onto prepared baking sheets and gently press with fingers to flatten into discs (note that cookies will not spread while baking). Bake about 24 minutes or until lightly browned. If baking two sheets at a time, rotate sheets half way through baking. Transfer to wire rack to cool. Store cookies in an airtight container.
