Step 1: Prep the Oven and Pan
Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy removal.

Step 2: Make the Brownie Layer
In a large bowl, whisk together melted butter and sugar. Add eggs and vanilla, whisking until smooth. Stir in cocoa powder, flour, salt, and baking powder until just combined.

Pour the brownie batter into the prepared pan and smooth the top.

Step 3: Make the Cheesecake Layer
In a separate bowl, beat softened cream cheese with sugar until creamy. Add egg and vanilla extract, mixing until smooth. Pour over the brownie layer and gently spread with a spatula.

Step 4: Make the Cherry Layer
In a small saucepan, combine chopped cherries, sugar, lemon juice, and cornstarch. Cook over medium heat until thickened (about 5–7 minutes), stirring frequently. Remove from heat and stir in almond extract if using.

Let it cool slightly, then spoon dollops over the cheesecake layer. Use a butter knife or skewer to gently swirl.

Step 5: Bake
Bake for 35–40 minutes or until the center is just set and a toothpick comes out with only a few moist crumbs. Do not overbake.

Step 6: Cool and Chill
Allow to cool completely at room temperature, then refrigerate for at least 2 hours (preferably overnight) for clean slicing.

Step 7: Slice and Serve
Lift the bars out using the parchment paper. Slice into squares and serve cold or slightly chilled.
