One-Bowl Chocolate Snack Cake for a 9×9 Pan

Ingredients

1 1/2 cups all-purpose flour
1 cup granulated sugar
1/3 cup unsweetened cocoa powder
1 teaspoon baking soda
1/2 teaspoon salt
1 cup warm water or brewed coffee
1/3 cup vegetable oil
1 tablespoon white or cider vinegar
1 teaspoon vanilla extract
1/2 cup chocolate chips (optional, for the top)

Instructions

Heat the oven to 350°F and grease a 9×9 pan.

Whisk the dry ingredients (flour, sugar, cocoa, baking soda, salt) in the pan or a bowl.
Add the wet ingredients (water or coffee, oil, vinegar, vanilla) and whisk until smooth.
Top and bake. Scatter the chips over the batter and bake for 28 to 32 minutes, until a toothpick in the center comes out clean.

Cool for 30 minutes and cut into 9 or sixteen squares.

Cook and Prep Times

Prep 10 minutes, bake 28 to 32 minutes. Makes 9 to 16 squares. This cake contains no eggs or dairy if you use dairy-free chips.

Fudgy Brownies

A standard two-egg brownie batter (about 1/2 cup butter, 1 cup sugar, 1/3 to 1/2 cup cocoa and 1/2 cup flour) fits a 9×9 pan in a thinner layer than an 8×8. Bake at 350°F for 18 to 22 minutes and pull the pan while the center is still soft.

Hot Fudge Pudding Cake

A chocolate batter is spread in the pan, sprinkled with brown sugar and cocoa, then covered with about 1 1/2 cups hot water before baking. The water sinks during baking to form a fudge sauce under the cake. Bake at 350°F for 35 to 40 minutes and serve warm with ice cream.

Chocolate Chip Cookie Bars

Half of a standard 2 1/4 cup flour cookie dough, or about 3 cups of dough, fills a 9×9 pan. Bake at 350°F for 25 to 30 minutes, until golden at the edges and just set in the middle.

S’mores Bars

Press a graham cracker and butter crust into the pan, add a layer of chocolate and then marshmallows, and bake at 350°F for 10 to 15 minutes until the marshmallows are golden. Cool fully before cutting with an oiled knife.

No-Bake Chocolate Oat Bars

Melt butter, sugar, milk and cocoa, boil for 1 minute, then stir in quick oats and peanut butter and press the mixture into a lined 9×9 pan. Chill for 1 hour until firm. No oven needed.

Chocolate Bread Pudding

About 6 cups of cubed day-old bread soaked in a chocolate custard of 3 eggs, 2 cups milk and melted chocolate fills a 9×9 dish. Bake at 350°F for 40 to 45 minutes, until the custard is set in the center.

Chocolate Magic Bars

Layer a graham crust with chocolate chips, coconut and nuts, then pour over one 14-ounce can of sweetened condensed milk. Bake at 350°F for 25 to 30 minutes, until golden and bubbling at the edges.

Converting 8×8 and 9×13 Recipes to a 9×9 Pan

From 8×8: use the same amount of batter; the dessert will be noticeably thinner, so reduce the bake time by 3 to 5 minutes.
From 9×13: make about two-thirds of the recipe and bake for roughly the same time, checking a few minutes early.

Frequently Asked Questions

How many servings does a 9×9 pan make? 9 large squares (3 by 3) or sixteen smaller squares (4 by 4).

Can I use a glass 9×9 dish? Yes. Lower the oven to 325°F and bake a few minutes longer, since glass heats more slowly but holds heat longer.
