Chocolate Brownie Tart with Melted Chocolate Sauce
A decadent single-layer brownie tart with crispy edges and fudgy center, topped with warm chocolate sauce. The instant coffee deepens chocolate flavor without tasting bitter. Semisweet chips provide balanced sweetness. Serve warm or at room temperature with whipped cream or vanilla ice cream for an elegant dessert suitable for dinner parties, holidays, or special occasions. This version distinguishes itself through the tart pan presentation, coffee enhancement, and homemade chocolate sauce rather than store-bought topping.

Tips
Bring eggs to room temperature before beating to achieve maximum volume and pale color, which aerates the batter for the best crumb.
Do not overbake; the center should appear slightly underbaked when puffed, as carryover heat will set it further while cooling.
Good to Know
Cover and refrigerate up to 3 days. Serve at room temperature or gently warmed.
Bake tart up to 2 days ahead; make sauce fresh the day of serving or store sauce refrigerated up to 5 days and reheat gently.
Serve at room temperature or warm, with whipped cream or vanilla ice cream alongside or underneath tart. Drizzle warm chocolate sauce over each slice.
Common Mistakes
Do not overbake past 40 minutes to avoid a dense, cakey brownie instead of fudgy center.
Do not skip cooling chocolate before adding to eggs to avoid scrambling eggs.
Do not overmix batter after adding flour to avoid overdeveloped gluten and tough texture.

FAQ
Can I make this tart without a tart pan?
Yes. Pour batter into a greased 9-inch round cake pan or springform pan. Baking time may vary by 5 minutes depending on pan depth. Cool and run knife around edges before removing.
What if the top cracks during baking?
Cracking is normal and desired for this recipe. It indicates proper browning. Do not open oven before 35 minutes as temperature fluctuations cause uneven cracking.
How long can I keep leftover chocolate sauce?
Store refrigerated up to 5 days in an airtight container. Reheat gently in microwave in 15-second bursts, stirring, until pourable. Sauce will thicken further when chilled.
