Instructions for Making Old-Fashioned Graham Cracker Bar Cookies
- Preheat oven to 350°F.
- Stir all ingredients together in a mixing bowl until fully combined.
- Pour into a lightly greased 8- or 9-inch square pan.
- Bake for 30–35 minutes, until lightly browned on top.
- Let cool slightly and cut into squares while still a little warm.
Tips for the Best Graham Cracker Brownies
- Don’t overbake. These should stay soft and slightly gooey in the center.
- Use fresh graham crumbs. Crushing whole graham crackers gives the best texture.
- Score into bite-sized brownies while slightly warm, but cool before cutting completely. They’ll hold together better and stay fudgy.
Can I Make These Without Nuts?
Absolutely. Simply leave out the walnuts for a nut-free version. The texture will still be soft and chewy.
Are These Really Brownies Without Flour?
Yes and that’s part of what makes this recipe so special. Vintage cooks often used pantry swaps like graham crackers instead of flour, especially during rationing years.
The result is a brownie that’s slightly lighter but still rich and satisfying.
Can I Use Different Mix-Ins?
Definitely! Try:
- Butterscotch chips
- Coconut flakes
- Pecans instead of walnuts
- Mini chocolate chips
Vintage recipes were all about using what you had on hand.
How Do You Store Graham Cracker Brownies?
Store in an airtight container at room temperature for up to 3 days.
You can also refrigerate them for a firmer texture.
They freeze beautifully too. Just thaw at room temperature before serving.
