1Pour buttermilk into a bowl and add sourdough discard, then whisk to combine.
2In a separate large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt.
3Add the mini chocolate chips to the dry ingredients and mix until evenly dispersed.
4Make a well in the center of the flour mixture.
5Pour the buttermilk mixture into the well.
6Add vanilla bean paste or extract.
7Stir until just combined, being careful not to overwork the dough.
8Add salted butter to a baking pan.
9Place the pan with butter into a preheated oven at 450°F to melt and slightly brown the butter.
10Remove the pan from the oven once the butter is melted and slightly browned.
11Pour or drop the biscuit dough into the hot butter.
12Use a spatula to spread the dough evenly out to the edges of the pan.
13Score the unbaked dough into 8 or 9 equal rectangles or squares using a knife or bench scraper.
14Generously sprinkle turbinado or coarse sugar on top of the biscuits.
15Bake at 450°F for 25-30 minutes, or until deep golden, crispy, and bubbling.
16Add salted butter to a saucepan over medium-high heat for the whipped espresso vanilla brown butter.
17Allow the butter to melt and slightly brown while stirring continuously.
18Remove the browned butter from heat and mix in espresso granules and vanilla.
19Pour the mixture into a heat-proof bowl.
20Place the bowl with brown butter directly on top of a large stainless steel bowl filled with ice.
21Whisk immediately and continuously until the mixture lightens in color and thickens to a whipped consistency (2-3 minutes).
22Once the brown butter mixture is thickened and whipped, remove it from the ice bath.
23Remove biscuits from the oven and let them rest for at least 5-10 minutes.
24Serve the warm biscuits with the whipped espresso vanilla brown butter and an optional sprinkle of flaky sea salt.

Tips
Do not overwork the dough, it will seem sticky but trust the process.
Allow the butter in the baking pan to slightly brown for extra tastiness.
Let the biscuits rest for 5-10 minutes after baking for the butter to absorb.
Whisk the brown butter mixture over ice until it lightens in color and thickens to a whipped consistency (2-3 minutes), but don't overdo it or it will become too solid.
