Make any event special with this slightly sweetened caramel nut tart with easy press-in the pan crust - perfect when you'd like a delicious dessert that isn't too sweet.
Preheat oven to 350 degrees. Optional if your pan needs it: spray only the bottom of the tart pan with oil.
Add crust dry ingredients (flour, sugar, salt) to a food processor and pulse a few times to mix. Toss the cut up butter into the bowl and about 8 times until it looks like cornmeal.
Mix the egg and water in a small bowl, add to the crust mixture and pulse until thoroughly mixed, about 8 more times. It should just be starting to come together (don't mix until it's one big ball, that would be over mixing).
With floured hands, press into a 10.5 inch tart pan with a removable bottom. Use a small measuring cup with a floured bottom to press the dough evenly along the bottom and up the sides until it's even with the top of the tart pan.
Line the crust with parchment paper and pie weights or dry beans to cover the bottom.
Bake 25-30 minutes until lightly browned. Remove the weights by lifting the parchment and let the crust cool on a rack while making the filling.
Make Filling
Layer the nuts over the crust: pecans, walnuts, and then the slivered almonds, pressing the almonds down into the cracks between the nuts and sprinkling over the top.
In a medium saucepan, add the butter, brown sugar, honey, cream, and salt. Bring to a boil on medium-high and cook, stirring constantly for 1 minute. Pour evenly over the nuts in the crust.
Place in oven and bake for about 10 minutes until nicely browned. Set on rack to cool.
Optional Chocolate Drizzle
Melt the chocolate and butter or coconut oil in a glass container in the microwave - 30 seconds, stir, and about 30 seconds more. (OR melt in a small saucepan over low heat.)
Use a spoon to drizzle over the tart or scrape the melted chocolate into the corner of a baggie, snip a tiny section of the corner and pipe the chocolate over the top of the tart.
Sprinkle with flaky salt if desired while the chocolate is still warm.
Let cool completely before cutting into 12 pieces and serving.
Notes
*Alternatively you can use white chocolate.Make Ahead: Tart can be made 1-2 days in advance and kept covered at room temperature. Leftover pieces can be frozen for longer storage.
