Step 1

Preheat fan oven to 180 C or 350 F. Soften Butter in microwave on low/medium until only just soft (not melted)

Step 2

Add butter, vanilla and granulated sweetener to a large bowl. Use electric beaters to beat on low until creamy. Add peanut butter to the bowl and beat together on low until mixed in. (If peanut butter is firm, it may splatter when using the electric beaters. To mitigate, microwave peanut butter first to soften, but don’t melt.)

Step 3

Add one whole egg (yolk plus white), and mix until combined, add the second whole egg (yolk plus white and mix until combined. Add the third egg (yolk only)

Step 4

Combine remaining dry ingredients in a separate mixing bowl. Add the dry ingredients into wet ingredients and mix on low until everything is combined. Add the peanuts, and fold them through using a spoon (not beaters)

Step 5

Spoon mixture into an 8 or 9 inch pan, lined with baking/parchment paper. Scatter with additional peanuts on top.

Step 6

Bake for 30 minutes in fan oven at 180 C or 350 F. To test if they are cooked, poke a skewer into the centre and if it comes out with a few crumbs and the centre looks a little ”wobbly”, it is done. Let it rest on the counter, covered with a towel until it comes to room temperature.
