9x13 inch pan
Large Mixing Bowl
- 1 3/4 cups boiling water
- 1 cup oatmeal quick
- 1/2 cup butter or margarine
- 1 cup brown sugar
- 1 cup white sugar
- 2 eggs
- 1 3/4 cups flour
- 1 teaspoon baking soda
- 1 tablespoon cocoa
- 1/2 teaspoon salt
- 1 teaspoon cinnamon
- 12 ounces chocolate chips divided
- chopped pecan or walnut pieces
Preheat oven to 350°F. Grease and flour a 9x13-inch baking pan.
Place quick oats and butter in a large mixing bowl. Pour boiling water over the top and let sit for 10 minutes, until the oats soften and the butter melts.
Stir in brown sugar and granulated sugar until combined. Add eggs and mix well.
Add flour, baking soda, cocoa powder, salt, and cinnamon. Stir just until combined, then fold in half of the chocolate chips.
Spread batter evenly into the prepared baking pan. Sprinkle the remaining chocolate chips and chopped pecans or walnuts over the top.
Bake for 30 to 35 minutes, or until the center is set and a toothpick inserted away from a chocolate chip comes out clean or with a few moist crumbs. Cool before cutting. Serve as-is or with whipped cream or vanilla ice cream.
- Quick oats work best because they soften easily and blend into the cake.
- Old-fashioned oats can be substituted 1:1. Pulse them a few times in a food processor or blender first for a softer texture.
- Let the oats soak in the boiling water for the full 10 minutes before continuing with the batter.
- Don't overmix after adding the flour. Stir just until combined.
- Begin checking the cake at 30 minutes and avoid overbaking so it stays moist.
- Pecans or walnuts are optional and can be left off for a nut-free cake.
- For a coconut version, add 1 cup shredded coconut to the batter.
- Let the cake cool completely before covering or transporting it.
- Store tightly covered at room temperature for up to 3 days.
- Freeze cooled cake or individual slices in an airtight container for up to 3 months.
- Serve plain for easy transport, or add whipped cream, vanilla ice cream, fresh fruit, or melted chocolate when serving.
