Step 1

Preheat oven to 180C/160C fan forced. Line a 20 x 30cm slice pan with baking paper, allowing the long sides to overhang.

Step 2

Place flour, baking powder, sugar, peanut butter, coconut butter and vanilla extract in a food processorProcess. until coarse crumbs form. Add eggs and process until mixture just starts to come together.

Step 3

Use slightly damp hands to press mixture into base of prepared pan and smooth the surface. Use the end of a wooden spoon, dipped in flour to prevent sticking, to make at least 60 indents all over the base. Spoon the jam into a sealable plastic bag and snip off the corner. Pipe jam into indents. Sprinkle with the chopped peanuts.

Step 4

Mix the vanilla bean seeds, salt and extra 2 teaspoons sugar in a small bowl. Gently rub with your fingertips until combined. Sprinkle over slice. Bake for 25-30 minutes or until light golden. Set aside, still in the pan, to cool completely. Remove from pan and cut into 20 pieces. Top with the extra jam and fresh raspberries, if you like.
