Tamarind Chocolate Bars

Steps

1. 1

   Melt chocolate and butter

   • Chop the dark chocolate into small pieces.
   • Place the butter and chopped chocolate in a heatproof bowl.
   • Set the bowl over a saucepan of gently simmering water, ensuring the bowl doesn't touch the water.
   • Stir occasionally for 4–5 minutes until completely melted and smooth.
   • Alternatively, microwave in 20-second bursts, stirring between each, until smooth.
   • Remove from heat and let cool for 2–3 minutes.

   Ready when: Chocolate and butter are fully melted and smooth

   Tip: Avoid overheating; chocolate scorches easily and turns bitter.

2. 2

   Mix dry ingredients

   • In a small bowl, whisk together all-purpose flour, cocoa powder, baking powder, cinnamon, and salt.
   • If the cocoa powder is lumpy, sift the entire mixture through a fine-mesh strainer to break up clumps.

   Tip: Sifting prevents lumpy cocoa powder that won't fully blend into the batter.

3. 3

   Whisk eggs and sugar

   • In a medium bowl, whisk together the large eggs and brown sugar.
   • Whisk for 1–2 minutes until the mixture lightens in color, becomes pale, and increases slightly in volume.
   • The mixture should look light and frothy.

   Ready when: Mixture is pale, increased in volume, and slightly frothy

   Tip: Whisking in air helps create a better crumb structure in the bars.

4. 4

   Combine chocolate with eggs

   • Pour the cooled chocolate-butter mixture into the egg-sugar mixture.
   • Add the vanilla extract.
   • Whisk together briskly for about 1 minute until the mixture is smooth, glossy, and fully combined with no streaks visible.

5. 5

   Fold in dry ingredients

   • Add the dry ingredient mixture to the chocolate-egg mixture.
   • Using a rubber spatula, fold gently and slowly until just combined; no streaks of flour should be visible.
   • Avoid stirring vigorously, as overmixing develops gluten and makes the bars tough.

   Ready when: Dry ingredients are fully incorporated; no flour streaks remain

   Tip: Fold gently—stopping slightly before the batter looks perfectly uniform prevents overmixing.

6. 6

   Swirl in tamarind

   • Pour about two-thirds of the chocolate batter into the prepared baking pan and gently spread into an even layer.
   • Drop 8–10 small spoonfuls of tamarind paste in an even pattern across the batter.
   • Top with the remaining chocolate batter and spread gently.
   • Using a toothpick or small knife, drag it through the batter in a loose back-and-forth or swirled motion to create a marbled effect.
   • Avoid over-swirling.

   Tip: Under-swirling is better than over-swirling; you want distinct pockets of tamarind flavor throughout.

7. 7

   BakeOven 350°F / 175°C

   • Place the pan in the preheated 350°F (175°C) oven.
   • Bake for 20–25 minutes.
   • The bars are done when the top surface is set and matte and the center still jiggles very slightly when you gently shake the pan.
   • Insert a toothpick into the center; it should come out with a few moist crumbs clinging to it, not clean and not wet.

   Ready when: Top is set and matte; center jiggles slightly; toothpick has moist crumbs

   Tip: Overbaking results in dry, cakey bars. A slight underbake is better for the fudgy texture.

8. 8

   Cool and cut

   • Remove the pan from the oven and place on a wire cooling rack.
   • Let rest for 10–15 minutes so the residual heat finishes setting the interior.
   • Using the parchment paper overhang, gently lift the entire sheet of bars out of the pan onto the rack.
   • Allow to cool completely, about 45 minutes, until firm enough to cut without crumbling.
   • Using a sharp knife, cut the sheet into 16 equal squares (4×4 grid).
   • Wipe the knife clean between cuts for neat edges.

   Ready when: Bars are firm enough to cut without crumbling or falling apart

   Tip: Cooling completely ensures clean cuts. Warm bars will crumble.
