My take on the layered brownies TikTok trend, using OREO® and Biscoff® cookie layers between layers of my classic brownie recipe batter. My family was begging for more after this was done!
It's important to use real butter, not margarine, for this recipe. Margarine affects the final consistency.
If you line the pan with parchment paper before greasing, it makes it easier to remove and slice the brownies.
You should end up using about 16 OREO(R)s and 12 1/2 Biscoff(R) cookies.
