These 4-ingredient tahini brownies are rich, fudgy, and just a little bit nutty, in the best way. They start with a boxed brownie mix (because honestly, why mess with a good thing?) and get a flavor upgrade from creamy tahini that makes them taste totally homemade. Think of them as the grown-up cousin to my Tahini Chocolate Chip Bars, but with extra chocolate and that perfect swirl of sesame goodness.

Key Ingredients

- Tahini: Make sure to stir the tahini well in the jar before you measure it out. The oil sometimes separates and needs to be reincorporated. My favorite tahini is the Trader Joe's brand and Soom which are both smooth and creamy.
- Boxed brownie mix: Use a mix that you love on its own. My favorites are the classic chewy Duncan Hines brownie mix and the triple chocolate chip Ghiradhelli brownie mix. The tahini swirls into both of these really well.

All about tahini
- Tahini is made of just three ingredients: hulled sesame seeds, oil and salt. The seeds are toasted and ground to a pourable consistency.
- Tahini can be found in most grocery stores and is also readily available online.
- It's nut free and makes a great alternative to peanut butter for those who need nut-free recipes.
Brownie Variations
- Make in muffin tins: Spray a muffin tin with baking spray and fill each muffin cup about halfway with brownie batter. Swirl about ½ tablespoon of tahini into each one and bake. Baking time will be less than if making a whole pan of brownies.
- Make them vegan: Substitute ¼ cup applesauce for each egg in the recipe.
- Using mix-ins: Add chocolate chips, butterscotch chips or white chocolate chips to the brownie batter before putting it in the pan. Then proceed with recipe as written.
How to make tahini brownies
Preheat oven to 350 degrees and prepare a 9x13 pan by spraying with baking spray.

Step 1: Prepare brownie mix as directed on the box.

Step 2: Pour ½ of the brownie batter into the pan and then layer about ½ cup of the tahini on top of it.

Step 3: Layer on the remaining brownie batter, then the remaining tahini and using a knife or spatula, gently swirl the brownie batter and tahini together.

Step 5: Bake as directed on the box. Remove from oven and let cool before slicing and serving.

Special Diet Adjustments
- To make them gluten free: Simply pick your favorite gluten free brownie recipe (boxed or from scratch) and follow the same directions for swirling in the tahini as with a regular brownie recipe.
- To make them dairy free: As long as the brownie mix you use is dairy free, then this recipe is dairy free.
- To make them sesame free: You'll need to swap the tahini for peanut butter or another nut butter equivalent like SunButter or WowButter.
Recipe FAQs

Absolutely! Any classic fudgy brownie recipe will work. Just swirl the tahini into the recipe as directed before baking and keep the baking time about the same.
